True fact: Water cooling attracts the ladies. Before they were like "Oh...you have a stock air cooler, I have to go"...
+ArcadeGames
+ArcadeGames Buh... but I have so many FANS... okay I'll go now.
It doesn't work so well when you piss on there leg though. I guess well never understand women??
Women run from men who don't understand "there, their, they're".
Grammer burn, So many bitches getting wet just reading your comment...
I loved the information, I have to admit I felt uncomfortable with the Wheel not having the same ratio as in the game x(
That's the first thing I noticed haha
OMG Do a "retro-watercooling" build would love to see a watercooled pc using a heater core bonus points if the actual pc is old as well :D
if my loop leaks one day ill have to say "my water broke"
lol
T-wolfkick u made my day dude thanks.
BAHAHAH
Yeah...I save a lot of money on heating bills when I get my gaming on in the winter. I never need to have it on.
Lol
I had an episoide that was two weeks long last year that my heating went out on me. I turned on all three of my computers and was nice and warm in my computer room until I got the heating fixed. :D
***** you must be feeling cold most of the time 10 degree Celsius thats cold
bla alaa Imagine if it was fahrenheit instead of celsius.
ThaRamoHD you gotta be kidding that would be cold ps he has written c there so it is celcius
You say that getting higher flow will not help cooling, and as a thermohydraulics engineer I have to disagree. The heat transfer laws state that the velocity of the fluid (hence the flow in a fixed diameter tubing) has an effect on the heat transfer, and indeed it has. And THAT has been proven many times, like in nuclear powerplants where the water flow in the cooling system has an effect on the nucelar core temperature (see the wikipedia heat transfer page for basics).
In my opinion, you do not see a difference in your system because your heat-dissipation bloc (or fan) does not have the capacity to evacuate more heat than it actually does, so THAT is limiting your system and not the fluid flow in your watercooling loop.
The point has to been made, as it was really hurting my engineer self hearing you destroying the laws of physics ^^
Except that, good video as always, keep up the good work.
antigen5 Agreed.
antigen5 What about the order your pipes go? If it flows through the gpu, then the cpu, the water would be warmer from the gpu, so the cpu shouldn't get as cool as it would if the pipe went to the cpu first, right?
weterman4320 I think the reason it doesn't make a significant difference which order the loops runs in is because of water high specific heat capacity. Water can take in a large amount of energy before raising temperature. Also, the rate at which water can transfer heat is relatively slow compared to copper. So I believe the water moves through the loop too quickly to saturate it's ability to absorb heat, and thus it should only make a few degree difference throughout the components being cooled.
antigen5 I was looking for a comment like this. I'm also an engineer and I think that the key word here is "significant". As in " it doesn't make a significant difference". In theory the speed and flow matter and the order also matter but in real life you won't see a major (significant) difference because the radiator is the main bottleneck of the system. Get a better radiator and the performance will improve much more than if you change the pump, pump speed or order of components.
I'm mystified by the claim that flow rate has no effect on cooling because with relatively simple tests on my system it's quite easy to see. With a d5 on setting 1 vs 5 there is an instant 3C temp change on the GPU and CPU. I also have an aquaero and water temp sensors and as flow rate changes from just over 1lpm at low speed to 4.6lpm at full speed there is a water temp drop of a few tenths of a degree.
There is plenty of detailed testing that shows core temps directly affected by flow rate through blocks and rad efficiency increasing with flow rate.
These effects are relatively minor and offset somewhat by the increased heat dump of pumps as flow increases but to say it does not exist is just not correct.
Jayz you should download logitech profiler for you g27 so that the swing radious is the same in game as when you turn your wheel, so that turning is much more realistic
Very informative, very hilarious listening to your frustrations while racing.
Rebuttal on water pump. YES, it does technically make a difference. The fan/radiator removes the heat from the water. You are right up to a point, that fan can only cool so fast. But if the water is moving very slowly, you might as well not have a water pump as the water is the median which the heat is transferred through, and the pump is what makes the system more efficient. I know the theory behind cooling, but I don't have any idea of what the flow rate is, though I imagine it would be wisest to choose the average speed. Obviously Jayz would know far more about that than I.
Yep, this is correct.
I work with digital cinema projectors where the DMD chips are water cooled and if the coolant flow rate is to low for whatever reason things get very hot, very quickly and the thing shuts down to prevent damage. The flow rate in these systems is very high and has to be to move the heat away quickly enough.
It may well be irrelevant in the case if PC cooling though as there's a lot less heat involved.
Your 100% incorrect. The flow rate makes no significant difference to the cooling process. The only thing that would make a difference is if the water is stagnant.
Why?
Liquid moving in a loop has an equal heat distribution per molecule through out that loop for as long as each molecule is traveling at the same speed within that loop. If the loop consists of 1L of liquid the pump pressure only needs to pump that amount of liquid at a pressure that ensures all of the liquid in that loop is moving consistently at the same speed. Once that benchmark is reached and every molecule is traveling at the same speed it's cooling time in the radiator will be equal regardless of the speed at which the liquid is flowing.
Why?
If the liquid is traveling at a rate of 1L per minute through a radiator at a constant speed the temp of that entire L of water will have an equal temp provided the entire L is traveling at the same speed.
But why wont it cool faster if I pump it through twice as fast? I mean logic says twice as fast means twice the cooling right? Wrong.
A single radiator cools liquid based on two factors. The surface area of that radiator and the time the liquid takes to cover that area.
But that proves that twice as fast means more passes over the radiator meaning cooler right? Wrong.
If liquid passes over the radiators entire surface at 1L per minute and the entire L is cooled by 1 degree per minute with a single pass, increasing the flow rate to 2L per minute would mean that it now has to pass through the radiator twice to adopt the identical drop in temp.
This concludes that if 1L of water passes through once per minute and drops by a single degree pumping it threw twice per minute in an identical time frame would render the result identical.
Why?
Liquid is not a single solid state substance, the molecules move freely between one another creating no time laps between the heating of moving liquid. If a solid state object like metal is heated the energy has to travel from one molecule to another in a set manner limited by the laws of physics hot moves to cold and cold to hot. Liquid how ever has free moving molecules that travel and bump into random molecules billions of times in a single loop ensuring the heat is distributed equally and is not limited to a set patch or direction of flow.
Increasing pressure due to added components only need to reach the minimum pressure required to eliminate any sections in the system circulating the liquid within it's self stopping the equal flow. Pressure is required to the point minimum pressure required for the entire body of liquid to move at an equal speed.
Trip Sinclair
You're getting confused here. Insufficient flow rate means the volume of coolant moving across the components does not have the heat carrying capacity to effectively remove the heat quickly enough, so it builds up and the temp goes up.
It happens - I have observed it in a real life situation as described above. The greater the flow rate, the more of the cooling loop is available to dissipate the heat. There is obviously a ceiling where by increasing flow rate will make no difference, but claiming 1l/m
flow rate will perform as well as 1000l/m is just not true.
These are non-pressurised systems in my case.
You missed the obvious that the digits described in my comment was purely fictional due to eg purposes. The flow rate matters only to the point that all the liquid is moving at a constant rate. If your system requires a billion L/m then you need that, as long as the pressure is enough to create a consistent flow the temp will remain equal throughout the loop. This all depends on the surface area of your radiator. the flow rate needs to pass over it at the required volume the radiator is designed to cool the liguid P/M.
Trip Sinclair
So I was right all along ?
The flow rate needs to not be the bottle neck in the system, do you agree ?
Dang you nailed it, one thing you should have mentioned is that increasing radiator size increases heat capacity not lower temps as many many many people think, awesome video man keep up the good work
Jay your wheel in real life vs the game aren't in sync. If you want to fix this go to the logitech controller software and set your wheel to 900 degrees then apply.
He does that on purpose for maximum turning capability since that Logitech wheel doesn't turn very far.
And don't forget to also run the controller wizard in the game options afterward.
Would be cool to see some Project CARS 4K benchmarks in the coming months.
Deadrablade where did you get that information bro?
KrisH4vitab Tweeting @ jay
If you catch this comment Jay, I've also got a G27 setup and run Assetto Corsa. If you go into the logitech controller settings you can set the wheel up to register the full 900 degree rotation, then when you open AC go into settings and choose the "G27 + H-shifter 900" (or something like that) preset. It'll really help with making the controls way more realistic.
Also, props for the road racing community. I run track days with an old Toyota Supra that me and my dad set up for the track.
Hey Jay, I had no idea that you were a big Racing fan and had many modified cars. I share the same passion. What were some of those cars that you had, and what type of mods did you make for the Road Racing? Love all your videos, I hope to get a response from you. Rock on Brotha!
Hey there, i had a 1992 Z28 fully build suspension, Adjustable panhard bar, upper and lower steering braces, adjustable strut rates (no coil overs) custom rate springs, squared steel control arms, subframe connectors, massive sway bars, 295 wide rear Potenza tires on 18x10 wheels in rear, 255 tires on 18x9 front wheels. Go fast mods to the car were mostly bolt ons and AC/Smog equipment removed. Car pulled 1.1g on skid-pad and was pure Road car.
I had a "GO FAST" car for drags. 1995 Mitsu Eclipse GSX. DSMlink tuning, Garret GT35R Turbo, 2.3 bottom end, heavy duty axles (they still broke often) 17x8 235mm wheels/tires, Greddy BOV, Custom made Boost controller. With Boost lag (even with 2step, the GT35R was massive for a 2.3ltr) it still pulled a 1.7sec 60ft, and 11.2avg @ 125 in the qtr.
*****
Thats so sick man, thats great numbers to get out of such a fricking boat of a car. I had a 99 gsx and with the AWD the thing weighed more than a damn mini-van lol. I moved on from DSM's and now wrenching on a 93 civic hatch. Enjoy it a hell of a lot more, you can pull the engine out yourself and it weighs about 1900 pounds gutted. My 250hp is the same as 500 in an gsx, running a D series SOHC vtec 1.6 all stock internals boosted at 10psi.
***** That is so sick man, I was always a fan of DSM, (when they actually held together) lol. I know the older ones took a lot to stay together when running a shit load of power. I really appreciate the response man. Glad to see how much you interact with your fans and followers. -Cheers from Maryland brother. Rock On
Good video. You should have added that two water pumps or running your pump on high will create more heat as the pump itself produces heat. It might....might be beneficial if the two pumps run cooler if not ran as hard but a test would have to be done on a side by side with each system.
i love watercooling, You don't need a room heater during winter :D just play some games for a bit or watch a movie. Cozy as shit.
and then too hot in the summer if you already have a warm room.
***** that's why you don't play games in summer
+OnePercent
Your room will be exactly as hot with a watercooler as it will be on air. The heat doesn't magically disappear, it's still in your room. Actually, if anything, watercooling makes your room hotter than air.
Fus Ro Dah that's why i like it coz watercooling heats the room more efficiently
You are right there about pumps, i bought a cheapo £5 aquarium pump from amazon uk, ran it at a silent 5v and it did the same job as a £65 xspc bayres pump combo.
The absolute best coolant you can use is distilled water and Valvoline Zerex race coolant at a 90/10 ratio. If you absolutely feel you must run a dye in your tubing because you're not a fan of the pink tint the Zerex gives your coolant, stick with coolant leak detection dye used in AC units as it will never gum up and has less of an impact on heat transfer.
I have been running this coolant through a Lang D5 pump with a copper block/aluminum rad for 10 years with only 1 coolant drain, the coolant that came out after the first 5 years had no buildup and the pump has head pressure as high at 10 years old than it did when it was brand new.
+K31TH3R I was specifically wondering about using auto coolant. Neat!
+David Hoffnung Yeah I literally just walk down to the shed and get some car coolant.
+Devin Williams Of course de-ionized water and a kill coil are the absolute best for temperatures, but many people use EK blocks with nickel plating and EK themselves recommend not using silver coils. Copper, silver, and nickel are all close enough on the galvanic scale that it's OK with de-ionized water, but most radiators are brass and aluminum and that means you will end up with corrosion, maybe not for years, but it will happen, and the less anodic metals you mix, the sooner it will happen.
Also the difference in my loop from Zerex mixture, and de-ionized water was 3c at the same ambient, and IMO, well worth the sacrifice to add a yet unknown number of years without corrosion.
+K31TH3R you dont even have any signs of corrosion? , and for the first 5 years you didn't even add more , coolant/water?
Great video. Will add though that if you use distilled water, should really get a kill coil as well.
What about using a antifreeze mix as a corosion inhibitor? I have a aluminum radiator and copper blocks. Is it ok to use the antifreeze?
Jesse Trimble Antifreeze is a bit heavier weight. Ive not tried it, but those who have had said it add wear to the pump. Not sure how true that is.
***** It's 100% true. The pump in a car is built for that liquid not that little mini me pump in the water cooler. I put pure green antifreeze in my cooler and the pump burned out. Same as with tap water it also burned the pump out. So did it when I put a cap of pool acid in the water and it cranked out trying to use oil to. :) Guy has to experiment, how else do you learn?
i only intended to put 20% antifreeze not 100%.
as for the heat issue im using a peltere water chiller so it does not matter. i can drop the temp as much as i like
Although with the tap water it's the high level of lime in our pathetic country that blocked up the motor. I will try and use a chiller from my old marine fish tank soon as I can get all the salt out of it to try and use anti freez again but with a fish tank pump not the water coolers internal res pump. just struggling to slow the pump, once you reduce voltage it spins in stages not consistently slower. That can get the liquid down to about 3 degrees. I want to know what the limit of this AMD CPU is.
please make a video about your modified cars
Hey Jay! I have a question, why wasn't the whole racing thing and modified car thing in your "Draw my Life" video?
my mother, who i havent seen in 2 years, had my brother bring me up her 5.1 surround system that she wanted me to have for my birthday.
it's the same as Jayz!
Having a masters degree in engineering, and also working daily with the thermal design of heat exchangers (industrial size), I have to disagree with Jay. The velocity of the fluids in the exchanger matter. The higher the speeds, the better the heat convection. What limits the speed is the size and pressure loss of the system. Now, in a computer, with flows and heatloads being as small as they are, with the delta T not really being that great, the difference in the fluid velocity might be miniscule. But if what Jay is saying would be true, we would not need a pump at all, we could just use stagnant water. The fluid speeds matter, on a categorical level. For practical purposes in a pc-loop, maybe not so much.
+niklas holmstedt Indeed... I also was confused as to why pumping 60 degree fluid into your CPU block would result in the same temperature drop (on the CPU) as pumping 25 degree fluid into your CPU block.
Exactly
Matthew Evans short answer: it wouldnt.
exactly. You hit diminishing returns, and its totaly possible that in most PC loops you hit them on the lowest pump setting (I havent tested), but there is a minimum flow rate you have to hit before that.
Also, loop order does matter to some extent. If your flow rate is quite high then the heat saturation of the water does even it out, but comp flow rates are pretty low. It may within the standard of deviation, but order certainly affects temps, especialy with ultra high heat dump systems.
I, too, have an MS in engineering (my thesis was on heat transfer), and you are forgetting that this is a closed-loop system. So while in an open-loop system, higher fluid velocity == better heat transfer, in a closed loop system that must be balanced against the lower rate of heat transfer on the radiator end.
Best tech channel on youtube for my money, great videos. thanks
11:00
sorry mate, but your simply wrong... if that were the case then there'd be no point in fans at all, anywhere in your system (after all, air is just another 'fluid' as far as thermals are concerned, and the more air/water flows over your heat sinks/radiators, the cooler your system is). You refute your point yourself when you say 'overcoming restrictions in your coolant lines' - if flowrate didn't matter then multiple restrictions in your lines (ie things that slow flow rate) wouldn't need a larger/more powerful pump to 'overcome' them. The larger the delta T between the inlet and outlet of your cooler (or really any 2 points in the coolant loop) the more there is to be gained by higher flow rates. Now for sure, there's a point of diminishing returns, and that point may be quite low as far as the typical flow rates achieved by coolant pumps, but the statement that it makes no difference simply is not true, otherwise pumps wouldn't even be necessary.
After about 1-1.5 GMP your pumps speeds do not matter because the pumps will generate more heat than they dissipate. Since he is racing we can use a simple analogy.
Think about a race car on a track. If the track is one mile (5280 ft) long and the car is driving at 60mph, the car will spend about one second in a 100 ft stretch. Think of the 100 ft stretch as the radiator.
If the speed is doubled, the car only spends ½ a second in the 100 ft section, but it passes through that same section twice a minute, so it spends a total of one second in the 100 ft section per minute.
In liquid cooling unless you are using refrigerated rads or a phase change system you cannot get cooler than the ambient temp of the room.Say the room is 20 °C and your system is 20 °C using 1 rad and pump at 1GPM, its doesn't matter if you put a pond pump pushing 10 GPM you cannot get cooler than 20 °C in fact you might make your system hotter by increasing your pump speed because the pump is going to start producing a crap load of heat into the system which you put into the air making the ambient temp higher.
TL;DR the only time you need to increase the pump speed is if you add more components into the line like a new rad or blocks for the GPU.
watercooling is a closed system, air cooling is an open system, increasing fan speed increases the rate at which fresh new air is passing over your heatsinks.
likewise, increasing water flow rate, since it's a closed system, would only hamper your water from gaining heat from the hot parts and losing heat from the cold parts.
OnePercent sorry mate but no... larger delta T means higher quantity of heat is transferred per unit time. so if your water is stationary, it may well get hotter than if it was moving, but there's no doubt that that'd result in less heat being transferred _away_ from the hot body. keeping water moving means that that delta T stays as large as possible, continuing to remove as much heat as possible. And secondly its not a closed system, since the heat is eventually transferred to atmosphere via the radiator just like any other heat sink.
Ask yourself why heat-pipes work so much better than solid (ie stationary) copper? because they physically _move_ the fluid inside them away from the heat source, and bring fresh, colder fluid in to replace it.
Increasing fluid velocity reduces the amount of time a fluid can lose its heat because it is exposed less to the cold part where it can lose its heat.
OnePercent yes, but its also going to have a lower delta T on the cold side, just like the hot side. if it moves slowly and cools down more, then its rate of heat loss falls too - reducing its effectiveness, because although the water cools down more between the start and end of the radiator, the system as a whole is moving far less _heat_ from the hot end.
Like i said - think about the extreme case, a fluid moving so slowly that its almost stationary. its able to loose all its heat by the time it reaches the end of the radiator, but because its not moving, its not transporting any heat at all. its just holding it there.
compare that to a very high flow rate. yes, each bit of liquid near the hot end is absorbing less heat each time it passes the hot end, but by continually moving, its taking whatever heat it does absorb away as quickly as possible, so that it can then be replaced by more cool liquid.
If what you were saying was true, then there'd be absolutely no need for fans, anywhere.
www.engineeringtoolbox.com/water-flow-rates-heating-systems-d_659.html
specifically, equation (4)
explains it pretty clearly. basically, doubling flow rate doubles the heat flow rate. there's practical limits that arn't being accounted for, but the fact remains that higher flow rate means better heat dissipation.
I have a three way pex home manifold in my system and have killer temps.
I have 23C going into my three way and 27-30C out. Duel vid cards, north bridge and CPU I do not get adding of heat between steps as when you run it in series. The max temp I get in summer is 49C non a/c'ed room.
Great video and thanks.
only complaint is, that you play with only 200 degrees on the wheel, while the game can handle 900 degrees. other than that, good video.
That timing at the end where you stop narrating and speak after the race was really cool. Nice editing trick.
just get a premade water cooling loop and be done with it. fuck it.
Liking your setup jay. While you were yelling at the other drivers all i could think is how funny a "road rage with Arnold" video would be
Electricity generates 3.413 Btu's of heat per watt of power consumed. If you use 1000 watts of power through the computer, you are generating 3,413 Btu's of heat. It doesn't matter if the heat is transferred from the computer by air or water, it is in the room. The water cooling system is more efficient, so it will raise the room temperature faster since it is absorbing the heat at a higher rate. In return, the system operates cooler. However, as the room gets warmer, both the air and water cooling become less efficient. The liquid moving through the system will have a differential [cooler after it goes through the radiator]. If not, the radiator is not removing heat and the system will overheat.
If you are gaming in an enclosed room that has central heating / cooling, check to see if there is a return air duct in the room [where air is pulled from the room back to the central system]. If not, you can put a transfer grill in so the heat building up in the room can escape. Letting that air escape will help the room cool down and help keep the computer from overheating. You can easily check this by closing the door and turning the central system on. If the feel air escaping from under the door, then there is no return duct in the room or it is undersized. If this is the case, the heat will be trapped in the room since the heat is rising and the cool air is being sucked out of the room under the door.
Your statement is mathematically impossible. "Electricity generates 3.413 Btu's of heat per watt of power consumed. If you use 1000 watts of power through the computer, you are generating 3,413 Btu's of heat."
By your numbers, it would be 3,413,000 Btu's of heat
Read closely James.... 3.413 Btu's/w is correct. That would be 3,413 But's total per 1,000 watts.
Dwayne Akers
so, you mean 3,413 Btu's per kilowatt, not watt?
Dwayne Akers
oh wait, i'm sitting pretty far back. I saw the "." and thought it was a "," herpderp
Had to look twice myself!
Thanks Jay love your videos. I watch them anytime I want to try something new with my computers.
heh, you know what's actually funny here? It doesn't matter (at all) what cooling solution are one using in the PC, the dissipated heat in the room is the same. Simply put, the same amount of computing power will generate the same amount of heat. The cooling solutions only differ by HOW FAST (dynamically) can they take that heat from the processing units to - guess where? - the freakin' room :). Probably, watercooling will cool the PU better, meaning - dynamically faster, and this means the room will heat faster, but in the end, after 2 hours of gameplay, the room temperature will be exactly the same regardless of the cooling solution. It's just physics ;)
NO cause the water cooling will make you sweat more cause you will be thinking you need to play extra hardcore cause your a pro cause of the cooling
dat was so funny Jo :))
Actually the resistance of a semiconductor gets lower at higher temps.
So a hotter cpu at, lets say, 80 °C uses (a little bit) less power than a cpu at 40 °C under the same load.
Considering this, a well cooled rig needs slightly more power to run and therefore dissipates more heat than a badly cooled System. Furthermore the cooling solution itself also generates a bit of heat which gets dumped into the room as well. The more sophisticated your cooling solution is (pumps, multiple fans...) the more power it requires.
It all depends of coures on how far you take it. Under normal or "non-extrem" conditions the power differences are most likely negilible and the room temp should be more or less the same.
It's just Physics, but there is a little more to it than one might think at first;-)
Actually you're less than half right. A semiconductor indeed gets lower resistance, but the overall wasted heat is roughly the same, just faster transfer to the cooling surface/slot (the sc gives up heat faster). In your theory, a hotter CPU should run better than a cooler CPU due to better use of energy and this is false. The only energy loss of any electronic component is always heat. That whole heat goes in the room, unless the PU is using that heat as processing power and cool itself (silly joke). Just physics :)
***** The complete power P=(V^2)/R gets converted into heat eventually. R gets lower with higher temperature, voltage stays the same, means power consumption grows?
R doesn't actually change nearly enough to cause any measurable difference though.
Thank you for posting this video.... You just answered my biggest question i had about water cooling....
I spent too much time watching you play then actually listening :( sowry
VolubleWhistle more; than
palonazo :(
Rik Dusk :(
Hey Jay, thanks for your videos. I've been geeking out over your water cooling builds. I'm amped up ready to build a new rig and try my hand at hard piping. Like you I'm a car guy though and I'm building a car up. Trying to budget both isn't going so well. Lol thanks again for all of the vids.
8:05 Oh Shit XD
Love your channel, you are an absolute pro in my opinion. I have a fully watercooled system (cpu, two graphic cards and the mainboard watercooled and use an external Aqaduct 720XT Mark III with a cooling capacity of up to 1400 watts. Normally the six fans are just running at 20-25% speed. Water flow is around 32-40 litres per hour, depending on the temps. All components are cool (50-60 degress C max) and the system is very silent (most important for me). In the end, the external cooling tower is 1,5 metres away from the PC, which brings the heat far away from it. Sadly I do have the red fluid in the system, so I will have to check for problems in the future.
I'm a little frightened to ask this, because I know someone out there is going to be an asshole about it. But is there some kind of component that is a radiator and attaches to the video card? Without the whole water cooling pump, and liquid or whatever. If this even makes sense. I guess what I'm asking is that, is there a way that I can cool my graphic card without a water loop? I'm an idiot when it comes to water cooling or cooling in general. So please, don't reply with something mean.
Yes there are fan cooled ones
Fan Cooling, what most videocards come with. you can get closed loop water cooling solutions that are sort of a plug and play thing for people who don't want to custom roll their own like the closed loop CPU water coolers.
The problem with the ones for videocards is that they are somewhat more videocard specific.
So you mean something like the NZXT Kraken G10?
Yup.
With the NZXT Kraken G10 you can use a closed watercolling loop such as the NZXT Kraken and use that to cool your GPU its verry efficient and qiute
Well i had to watch this twice. Came for the commentary, stayed for the driving gameplay. Inspiring Jay.
just a note about the wheel, set it up so you get the full 900 degrees of rotation, so the game is 1:1 to what actions you are making.
jay i think the greatest point you got across in this video is that the logitech g27 is an awesome steering wheel. i am sold!
Your steering sensitivity is very high. I may not know much about water cooling (hence me watching this video) but I do know about sim racing. If you want or need tips on wheel settings I'd be happy to give you some good rules of thumb.

hey jay what cars have you own ? show us some day what you drive or use to drive
if you have problems with the force feedback, try to reduce the sensibility of your wheel, so that you turn the wheel the same amount as in the game ;) makes it way easier :D
regarding the order of the components, do you also mean that the reservoir before the pump is just for the bleeding purpose, then once fully filled, no impact anymore?
Thanks for the info. It'll help when I get my system built later this year.
what causes the dye "gumming up", isn't the dye itself. it's the plasticizer building up in blocks, which ends up looking like dyed sludge. but it isn't the dye at all, it's the tubing breaking down over time in your blocks. now, certain dye's can cause tubing to break down at a faster rate, allowing your blocks and radiators to become clogged up more frequently. Primochill Advanced LRT has been from my experience the least likely to break down quickly (I've used XSPC, Danger Den, MasterKleer and Primo Advanced LRT)
Great video, was nice watching from (actual) over shoulder perspective!
You should either make a video or an article about your time when you were racing. I would like to know how you got started and what you were racing and other car nerdy stuff. It would be cool
Thanks for awesome video, race, and advice. I want to water cool now! I always thought that distilled water would be better than the super chemicals out there. I watched some other video that said the same thing. That video also mentioned what you said about the speed of the pumps and order of components being cooled.
As a engine builder when your trying to even out cyl temps in a race engine. I find cyls 2,4,6,8 for ex. are at different temps cyl 2 runs cooler then cyl 8 with some mods to the block and cyl heads you can get them close but they're never right on one to the other, wouldn't it be similar with a computer running your coolent through the hottest part first would raise the temps of the cooler one unless that heat is dissipated quickly?
Jay, you should try increasing the degrees of rotation on the wheel. Assertion corsa is made for 900 degrees.
one of the most awesome channel out there! thanks bro for the vids
Question: Motorcycle water cooling will become more efficient as engine RPM rises and fluid is forced faster past components(think wind chill). So coming from a deep physics and chemistry background, I do believe that a faster pump speed would, in fact increase the cooling capacity of your system.(Assuming your radiator fans can support and ramp up to get rid of the heat faster) Watts are J/s so therefore pushing more coolant through a radiator at constant temperature faster gives more wattage displaced into there air....? Thoughts?
Hi Jayz love your video but it would have been better if you explained WHY a higher pump speed doesnt make a difference to temps.
Its seemed counter intuitive as more water flowing over the heatsource which shoudl techincally have a bigger Delta-T right even if very minor.
Sso i did some research and tested it on my loop. For anyone wondering why this is, basically the pump is producing more heat at a higher speed as it uses more power, typically pumps dump the heat into the loop wich counters the higher flow rate.
So my question is to you Jayz, would attaching a heatsink to a pump effect temps enough to justify a heatsink on for instance a D5? At max pump setting a D5 has to displace 24W, how many degrees could this add to the loop? Especially if your rad is maxing out how much heat is can displace.
Thank you bro! Always answering my questions with your videos!
Hi Jay loved the video, those things needed to be said and by professional good work.
There is one thing that you may want to address if you do another water cooling vid is that the speed of the pump not mattering is only half the story. Some people may need to know why that is the limitation if they’re making a custom cooling kit rather than a stock one.
The farce of the water moves the more energy picks up that will be good if you could dissipated the head as quick as the water picks it up. If you had large surface area radiator with higher CVM fans on that radiator. The speed the water flows would increase cooling. If that heat is not dissipated by the radiator, water speed does not matter.
Heaton distillation is one of my things
Nice vid!
Also a common "advise" is that you NEED 2 pumps if you want to cool both CPU and GPU or add extra radiators which is completely untrue. With almost all blocks and radiators being extremely High Flow nowadays its total overkill and an extra pump will also create extra heatdump. I HAVE 2 pumps with only 1 of them running and the other acts as a failsafe should the first one go to the eternal watercooling fields :-)
I rarely, if ever, subscribe to people. But you sir are worthy of me being subscribed to you. Keep up the good work and dont fuck this up.
Wow, I bet he is so fortunate for "sugarpuffextreme" to subscribe to him. Whaaaat an honour. I suuuure how he lives up to yooooour standards.
***** Kiiiinda.
The more I watch your videos, the more I realize how much inspiration that Barnacules Nerdgasm has taken and put into building his own channel
Take this with a grain of salt, but the pump speed will have near-zero bearing on the temperature of the loop, as the ability to heat and cool the water will be fairly proportional,. the surface area of the radiator will be far more effective in determining the the loops ability to transfer heat.
Cool video about water cooling! Thanks!!
Jayz! Tip for your force feedback problems. Yes, force feedback is not perfect, but on this video, you been driving with the wrong steering setup. You had to use very very minimal steering angles, so probably your G27 is at its default 270 degrees in its driver but assetto corsa expects 900 from a G27. Check your profiler settings.
I like your reviews. Good work fella!
Your actually a really good youtube, I'm a new sub, but yeah your one or not that much I enjoy watching!
Would it be possible to make or put in a distilation system for a fluid? Just a question.
You need to change your settings in game. Set your wheel to 720 degrees in game. That will make it so thew turning is 1:1. Also you should try a driving game called live for speed! There is many online servers for f1, drifting, and rally. You also can completely customize your car. The game is amazing but it just lacks graphics...
got watercooling for years now, (8 years to be exact) i've gotten my few share of leaks (wich all were my fault and the fault of bad research and not being carefull) and i have 0 failures to date. My last computer had a big leak, and it stopped working a week after the leak, after research i found that the watercooling residu had dried up in the pci slot, wich caused the connection to be faulty, cleaned it out, and it works fine now.. so is it dangerous to run watercooling? i think the risks arent as high as everyone thinks.
personally i think overclocking your system, is as dangerous as watercooling itself.
What kind of car did you used to race Jay? That's awesome by the way!
Any real difference in vertical and horizontal radiator mounting? It seems to me that vertical radiator mounting tends to store sedimentation of pigments or whatever at the bottom and also make it harder for the fluid itself to circulate within, stressing the water pump a little more. Does this make any sense to you?
Yes, the so cold nonconductive fluids will eventually gain conductivity but so will distilled water. I still don't fully understand the advantage of using distilled water if cost and colour is not an issue. I mean, I am sure there are coolants/fluids that are dyed(not red) yet don't deposit in the radiators.
9:22 jay why didn't you mention putting your radiators in another room? that's pretty practical right?
Might be a stupid question, but what if you didn't use a radiator at all, just have a loop with your res, cpu, gpu, and pump. Would you just expect the temperature of the liquid to gradually heat up?
Yeah, it would heat up alot!! Because nothing is cooling it down
Angel Luis Trinidad That's what I figured, was just wondering how long that will take, especially if you have a large res
I was wondering, how often will I need to refill a loop that has may hams orange pastel coolant? I want to also now how would I clean out the gunk from the rads and blocks? I want to know because I am building my first water cooled pc and these details are very important to me.
Looks like the wheel is set up with too high sensitivity, you are having trouble catching the slide. Also i think you are spending too much time on the shifter, should go back to 10-2 as quickly as possible.
Do you ever make videos from your iRacing? What series do you take part in?
But thanks for the insight on watercooling! I am thinking of going from high end aircooling to custom water cooling so its really useful.
Hey Jay, if increasing your pump speed doesn't affect cooling capacity, why are EK's pumps PWM controlled?
If my computer radiator leaks I will have to say "my water broke!!!"😂😂😂😂😂
you should have more rotation on the G27, to match up the ingame wheel.
It will make it behave more like the real thing for sure ;)
Lovely video, I love to learn stuff about watercooling(and I also love sim driving) :D
Keep up the good work ;)
I'll admit, I'm only 50 seconds into the video while typing this, and that this video is from 2014, but your comment of old style water cooling (the aquarium pumps and such). Do you think in the future you might be willing to a build like that again for the sake of a video? Kinda show the progression of water cooling.
man! great setup! thinking about getting one of those G27s.
I need a third screen and a g27.. It looks stunning.
have the same system just wondering why your front speakers are so close to each other. sounds better further apart
So hard to find truly solid and conclusive evidence of water vs air cooling.. IM just gonna buy two, test them and return the one that performs the least
If you could have the radiators outside, with well insulated connecting tubing (unlike linus tech's attempt) then you would reduce the heat in the room. Otherwise water cooling would be dumping more heat into the room due to energy displaced by the pumps.
I just placed my first order with Lutro0 Customs. Thanks for doing that video about them.
Quick question for anyone that can answer. I've read this somewhere a while back, and I'd just like to know if it's true or not. In watercooling, is your build only as cool as your room temperature, or is this not at all true? Also, what are your thoughts on the Corsair H80i?
Kevin Canterbury Heat only transfers from higher to lower temperature so room temperature is the lowest one in your system. Room
You should enable independent rendering if playing sims like rFactor 2, Game Stock Car, Assetto Corsa, IRacing,. Unlike mainstream games, these games actually do proper independent rendering for triple screens users in order to have no stretching and distortion on the outer monitors.
Do more of these "gameplay" videos jay, it was fun to watch.
The fact that increasing pump speed not having a positive effect is interesting, as nzxt has made the kraken x41 and x61 have selectable pump speeds.
Would liked you to have mention subzero cooling, good old nitrogen with its pros and cons and compare it to water cooling :).
The order of the loops does matter in at least one case: If you run a system with 2 radiators at the same exaust vent, you want the air to go through the hottest radiator first, then the cool one. The reason for this, is because of the way heat transfer works, it is not a linear development, and the same thing applies to the components: Hottest components first. The reason for this is that the heat transferspeed is not directly proportional with the Delta-temperature. Thus the transferspeed is higher when the heat difference between the components and the water is higher, and likewise when the speed is lower then the temperature difference must also be lower.
When that is said, I would then recommend not using the same loop for more than one component, unless you're having space issues, especially when thinking about the space you need for radiators. The point is that every component should have room temp water flowing into them, this also means that a bigger resevoir is better so, the water can cool down completely before going back into the system. Alternately you can increase the number of radiators, to cool the liquid(s) down as much as possible, before having it reenter the loop.

On the topic of whether or not a water cooled system would heat your room faster than an air cooled one: I think that if you have two identical systems - same CPU, same GPU, same voltages and frequencies and so on, one cooled by water and the other by air, they would produce exactly the same amount of heat, it's just that the water cooled one would probably dissipate that heat faster.
Jay you need to set your wheel to 900 degrees on the Logitech profiler and use the default settings in game for the G27. Will make a big difference to you.
Yeeah, Assetto Corsa!
I really like your Vids, learning much of them. Just curious about your Wheel-holding-style :D
keep on doing what you're doing. Cheers
red dye... not just terrible in cooling, but also in sport jugs. 5 gallons of red powerade/gatorade will stain. i feel you jay
Jay, I want to see you build a "ghetto water cooler" :)
This was really fun to watch actually.
How are you liking the G27 Jay ? I just got one myself a couple days ago and I love it.
