From 4 years in the future, this version of Jayz looks too young. 3/5 would not time travel again.
Fox same
Yeah, seriously. Current Jay radiates dangerous amounts of DILF energy, but here he's at this awkward point between looking young and more middle-aged. It's uncomfortable.
@@wynderlacunae268 Fully agree.
Don’t worry he has currently hit his mid life crisis dad look
Front radiator mount is inefficient. You are bringing heat back into the case
There actually is a difference between pushing and pulling through a resistance. But it is probably negligible in this context.
We did some testing on this in college for designing a wind tunnel. Basically, if you are pushing air through a radiator, the air is turbulent as it goes through. This means the turbulent air has to straighten out and loses more energy in the process.
However, when you are pulling air THROUGH a radiator, the air is starting from rest, so can be pulled in any direction it needs to, and the flow would be laminar.
This is also another good reason to pull air through filters, rather than push. Besides protecting the fan from dust, it is easier to pull through a filter than to push through it. At least in close range.
So in theory would a pull configuration be slightly quieter since the air isn't as turbulent going through the radiator fins?
Hadn't thought about that. But yeah, that would make sense. Would need some empirical evidence for it to be sure.
LinusTechTips did a test on push/pull vs push vs pull. No difference (outside margin of error) at all when dealing with the scale that you see in PCs.
ah good! I scroll down and find a bit of scientific experimentation on the matter, thanks :)
Good point, but turbulent air is better at removing heat from a surface. It's why good intercoolers on cars have turbulators inside the tubes.
Nice job explaining the various configurations. I've been saying I'll water cool my next machine for about 10 years but end up air cooling each time. I found everything you said here to make perfect sense and it should be easy to understand for anyone looking to get into water cooling (like I STILL am). Thanks Jay.
i would be building my first liquid cooled pc and i am watching a 5 year old video. nice
I have a question, is it possible to make a water cooler intake while the radiator is on the top? And not on the sides?
@@duiwithc4corvette403 im no expert but I'm going to say no because that would be causing a lack of exhaust in your system. You want to keep airflow neutral meaning even intake and outtake.
ha! you too? How'd your build go? I have my stuff showing up in the next week or so.
@@duiwithc4corvette403 I assume you're talking about air intake (related to the video). Sure it can! In some cases where the top is too blocked off it can even cause better cooling performance compared to using them for exhaust (because it wouldn't be recirculating hot air from the case). But if you have too many intake fans and not enough exhaust fans or just holes in your case the air pressure differential could (theoretically in extreme cases) become too high. This could generate noise from air escaping through small holes in the case and could make airflow optimised intake fans run very inefficient. Though for radiators pressure optimised fans are the go to choice. Slightly positive pressure would have the advantage of dust only building up on the intake fans which you could use a filter for.
But I don't really expect it to be an issue since most cases of the last few years have more restrictive intake problems while the back of the PC is very well ventilated so it should be fine to use the top fans as intakes with the radiator on top (in a pull config) but the exhaust side of a fan is usually not as pleasing to look at as the intake side.
considering the info is wrong, good luck with that
i coulda swore that was a headphone ad.
Agreed haha
Me too
i thought it was a microphone lmao
got "thumb up" for the add :)
It's modular
I'm just about to build my very first high end pc and i love the fact that everything that I have a doubt about there's a video fom Jayz covering it. Thank u very much
This was one of the most useful video's I've found for water cooling, I have decided for my Case labs Mercury S8 case to do a 280 mm push pull on the front but really quiet fans, this is my overall goal. Thanks again for the great video Jay
Nice video. Note that the temperature of the air pulled through the radiator matters, so the one mounted on the front provides maximum cooing on the radiator but can heat up the ambient temperature inside the case. For balance cooling, mounting it on top where the hottest air are expelled is what I prefer.
First denied! again...
***** NOPE beat you by 6 seconds
saph the sergal Did he delete your comment?
***** Nice work on the video, keep up the good work. #PlsNoticeMeSenpai
***** So,... forgive my noobiness here. Isn't PULLING air from the front radiator,.. well... pulling hot air INTO the case? I get the astetic reasons, but wondering how this affects temps in the case.
Isn't it possible to push air trough the front while mounting the fans at the same spot, just reverse them?
***** wow man you are looking good! keep up the hard work. I'm happy to see you succeed in your weight loss.
i LOVE the intro... i like it much better than the old one. it feels retro and just. good like
Yogert PC that's the intro of Tek Syndicate
it are good. very well upgraded
....
I’m glad I watched this video before putting my pc to the test. I had my fans pulling air from the radiator, instead of pushing air through the radiator. You sir saved my PCs life.
Jay, your videos are SOOOOOOO appreciated. I have no problem at all following along with your logic. Don't ever stop making videos dude. Seriously.
I do like pull generally simply because over the years I have noticed that dust accumulates much less at the radiator than in push configurations every time I've done it. Anyways, Great Video! Much agreed on the Cooling Differences! :)
This ad at the beginning was awesome :D
Awesome video! I now know all the basics of push, pull and push/pull air flow. Slowly I'll become a master like you Jay! Cheers
Great video. It helped me a lot! Thank you.
I have just finished my Corsair C70 Military build! So i went for 2 Noctua F12's on the front pulling air into the PC through the storage compartment (super quiet fans running at 1500rpm - it sucks in my 420 smoke!). 2 AF 140's on the top pushing air out of the case, running @ around 1000RPM each (again, very quiet fans and move a lot of air). On the rear I have my MSI Dragon 120mm Radiator with a Corsair SP120 pushing air through the rad and out the back of the case. It's worth mentioning my MSI Dragon Liquid Cooler is 18 months old (from a prev build) and still going strong. Obviously it's a good one, it's made by Asetek!! The pump is running at top speed (silent 1590RPM) and the SP120 @ around 2000RPM (super quiet). FX-8350 (stock speed 4.0Ghz) i am getting Idle temps of 18c-23c depending on weather and I haven't seen it go above 44c under full load (I play GTA V at 2k 60fps for hours on end!). So thanks again for making a great video, and hope my comment can help some folks out.
Dang Jay, you are looking hella good! Keep up the good work man!
scintillating awesomeness Thanks buddy.
***** Anytime :)
scintillating awesomeness how was the 3 years later?
@@noway9184 oof
>can't hear what your saying with headphones directly on your ears
>CAN hear the doorbell ring perfectly, no problem
wat
You always have the best water cooling vids my man - each component with it's own recommendations and basic guide
Thanks, great information. I built a custom loop a few years ago, and I just started a new build with Corsair's H115i AiO because I wanted to keep it simpler. Essentially, I'm hearing you say that there is marginal difference between push configs vs pull configs when it comes to temp. I always thought pull was more effective than push using fans with high static pressure. Do you think I'd benefit from push-pull on their rad if I've got the room? Would it be overkill? Thanks for the vid.
Edit: Should mention that I picked up two Noctua NF-A14 3000RPM to replace Corsair's fans. I was going to use all four unless I don't have the space or it isn't necessary for the rad's fin density.
"Something appears to have changed."
I run pull on my front mounted AIO in my A10-7870k SFF build for maintenance and appearance.
I can easily reach the fans from the inside if I need to take them down for any reason at all, and I can reach the rad from the outside for cleaning.
Plus you can't see the branding on the side of the rad, but you can see the fans, from the view window. If I take the front cover off, the rad's right there, giving the system a neat industrial look.
My build can run in partial passive mode, using only my single case fan to keep it cool (35c) at desktop and light loads, but peeking into the side of the case lets me see if the fans are running or if one has stopped for some reason. (I had to take one offline for repairs.)
....
Guys, why are you staring at me like that?
That fan commercial cracks me up every time I see it
That fan commercial cracks me up every time I see it
I lolled when i saw the ad at the start...great job!! This way advertising is the best way to do it
Love your videos! just wanted to say, your weight loss has been nothing short of incredible and I'm really happy for you =)
Jay's confused/worried face made me laugh out LOUD in my room late at night! XD
1:28 Wow! Not bad! 0.o'
In the beginning, the way he talks and his hairs make him look like the younger version of the giant from Twin Peaks :D
Another interesting perspective would be to look at an automotive application in which fans typically will be mounted behind the radiator in a pull configuration. I imagine manufacturers do this because many times you have an AC condenser in front of your rad and when stopped the most effective volume to which you can exhaust your heat would be behind the rad and in front of the engine. Of course in that scenario you're also dealing with much more powerful fans that will draw usually a minimum of 30 amps on their own.
You did a perfect job of explaining the concepts. I was really confused about push and pull configuration.
awesome ad Jay!
Keyvan Khadem Ravandi your fractal design ads are truly epic, that's how all ads should be! :D
can you do a video on overclocking for beginners ?
Yes please! Specifically on what aspects do what and which ones affect what in order to get the results you're looking for. Like how exactly does upping the voltage help, and what does the CPU multiplier do. How far to go, how far is too far. And honestly I have no idea where to even start with gpu overclocking. Do I need a custom bios, or is there an ability to OC from the driver software? I haven't really seen any video that cover these things, and I respect your ability on these topics Jay. Thanks for all the awesome videos!
Travis Mohan He has two overclocking guides, one for AMD and one for Intel.
***** That's fucking insane, thew cpu will melt with the first stress tests. Linus's overclocking guides are pretty bad.
Luis Ortiz amd fx 8320 at 5ghz 1.552 volts lol
chris simmons Damn!
I feel like a peasant with my 5820k running at 4.4ghz 1.22v.
Best video on youtube of this topic.
Forget Forums, Google image searches, articles. Just watch this
Thanks to Jayz!
im glad i have finally found a guy what could explain this properly. Im a novice in liquid cooling because i always used standard air cooling. I have bought the Kraken X62 for my new rig but need help how to install it. Thanks Jay
ok i LOVED that intro
Jay, turn on V-Sync for your intro.
I must have watched about 20 videos before finding yours. And this one was the most informative and understandable.
I'd love to see the air pressures with smoke!
Wouldn't having a pull on the front just pump the warm air from the front radiator back onto the components?
Doesn't matter too much since the components are reasonably isolated within the loop.
Well if you have an intake fan you will be blowing that warm air on an exhaust fan
thanx jay i was gonna change my fans trying to drop temps but now i know it doesnt matter and i have good flow keep up these kinds of vids
Old video I know but I wanna throw something into the equation for people who are lazy, like me for example. Pulling fans tend to collect less dust because they pull it out through the radiator and putting it straight outta the case instead of pushing it against the radiator and making it stick there.
Also thank you Jay for making a video that I can copy and paste over and over again when I´m getting asked these kind of questions.
I would do pull for exhaust fans rather than push, the different in air pressure is negligible but by putting it in pull any dust build up will be on the exposed side of the radiator rather than between the fans and radiator.. and therefore easier to clean
I think pull is better in any senario for the dust factor alone
Your looking really well ***** those bike ride's must be doing the trick ;-)
I like how you integrate your ads, making a fun skit out of them.
Ran out of rad videos to watch where I’m from, traveled in time for this rad masterpiece. Thanks Jay!
how about a video on how to sleeve psu cables?
***** link?
Jayz without a beard, interesting.
Yes and he looks way younger here and it's only a few years ago.
@JayzTwoCents FYI there are fan splitter cables that allow the PWM line to go to up to 5 fans while the power for said fans can be handled separately by a MOLEX connector from the PSU. This is helpful if you are running many fans or extremely high powered fans and don't want to burn put the fan headers on your motherboard. (Most motherboards can only handle 1 amp of power _total_ as you said in your video.)
Well, that advertising in the beginning was great! xD
I'm a big "fan" of these videos :D
I've only watched your videos for about a year, you always talk about how cringe you guys are sometimes but I never seen any trace of it. Today, that has changed. I have seen Jayztwocringe lol
Hey i'm planning on getting a Corsair Obsidian 750D and use a Corsair H110i for CPU cooling. What configuration do you suggest? I was planning on using it as a push - exhaust fan (2x140)
Making my first build and this was so helpful! Thanks!
One thing Jay failed to mention or at least I didn't hear him say it, correct me if I'm wrong, is that when you use a push configuration dust is much more prone to get trapped on the rad between the fan and the rad. This is why I choose to use pull 99% of the time. Unless like in your case you go for aesthetics, in which case you'd rather put in work so it looks better.
Dylesxic I'm lazy, so I do the same. less maintenance.
Just clean dust with water
My radiator still ends up being dusty even with 3 exhaust and 2 intakes 😂😂😂 I reallly don’t think it matters
@@civilian3541 this was referring specifically to where on the radiator(s) the fans were mounted as apposed to how your entire case's airflow is configured. I've used both configurations and with all other things the same, pull won't hold as much dust as a push set up will.
I'm a FAN of that new ad... No?
Alright I'll go cry in the corner of shame ;-;
I like it too,
You aren't alone :)
BrokenWillo It blew me away.
***** ummmmmm... ads* lol thats a bad typo xD. I hope it was a typo lol...
***** theres autocorrect on windows ten?!
***** lol okay
As usual, very well presented. Yes, we would like more!
Jay you are the man. The smoke and stuff to see how the fans work would be awesome.
Damn that Z looked nice.
Jay350zTwoCents
Now we know what the z is for.
Starman Dx or is it a 370z they look the same
!# TheMiningWaffle
We may never know.
!# TheMiningWaffle No they don't look the same. It's a 350, not 370.
!# TheMiningWaffle both look dope*
!# TheMiningWaffle the overall shape yes, but there are subtle differences e.g. tail lights
Perfect explanation, the best I have seen so far. Thanks!
Thank you sooo much. It made it so much easier to understand the process. I tried other videos but this one really helped me understand the process. Thank you.
The theme music made me feel like I was watching Tek syndicate
Did Linus not do a video a while back saying to only do pull because push can trap dust in the radiator?
erazorCTF Your still going to trap dust in a pull setup.. Much like any window A/C.
Grant Kidd Just get some Silverstone dust filters on all your areas with fans mounted and you're golden. They're magnetic so you don't even have to screw them in if you have an aluminum case (granted I did anyways) just wipe the fan periodically and enjoy fantastic dust free air pressure year round.
friedzombie4 Magnets won't stick to aluminum case and besides, I have one of those Silverstone dust filters - they restrict airflow so much that there wasn't almost any airflow in my case, so I removed that filter.
Tomas Sabalas oh wow, magnets how do they work? jk I am using a Fractal R4 so that's a steel case which explains why the magnets work well for me. Are you using the old filter design or the new one? I'm using this amzn.to/1DPosWH and haven't had a single issue with airflow.
friedzombie4 I have this one amzn.to/1JSkq1P and I guess it's the old one. I'm using Lian-Li case, so no magnets for me and I don't have any dust filters in my case, just a grill at the top - all I need to do is blow dust out of the case with air compressor once a year and that's it.
I've always found push configs on the front rad to perform significantly better but only for constricted front panels.
going between a vid a year earlier and this and compared to now, your looking great awesome job with the weightloss jay :) still a useful video jay :)
yea jay, do the smoke for skunkworks pleeez
4:25 Fan configuration in case
really like your simple and easy to get explanations. helps beginners like myself a lot. thank you.
Hell yeah I'd love to see some testing with smoke or vapor to see what happens under different pressure situations (pos or neg) Keep up the good work Jay!!
your buddy is great in every video I have seen him in
dave h love u Dave
Thanks buddy ;)
HOLY CHIZZLE-SWIZ YOU LOOKING SKINNY JAY! NICE WORK!
Amazing, very clear now. i was having difficulty understanding the difference of a configuration between of only fans airflow and a water cooled and fans. now it's clear.
I just ordered a Corsair icue H150i Elite Capellix with the Lian Li Lancool II Mesh Rgb. I think i will be a very good combination.
Thanks Jay!
thank you for all the explanations on case flow and fan designs.
I liked the video because of 350Z, uh i mean because of the stuff you talked about in the video... yeeeaah
IMO always install in pull if possible. Easier to clean.
Is a pull Radiator in Front okay? So:
------Case-Front-----
///////Radiator/////
Its in Front Not on top ;)
Yes, that's how my setup is. Temps are good, easy to clean.
Haxor inator okay thanks :) just thought there Is Not enough pressure for The radiator
There is a reason that cars do it this way. The fan pulls through the radiator and then blows it all over the engine that is making the heat in the first place.
Forget about pressure differences and think in terms of air movement, and that the three components here are part of one overall system.
uh should you get airflow fans or static pressure fans for a pull config?
5 years later. This intro is still gold.
I've had all my Radiators in a pull method for a couple reasons. 1st would be due to clearance size from a specific and having the fans to close to cabling or motherboard. 2nd Since I live in Cali and it's a dust bowl these days, I've noticed the fans do not clog up with dirt/dust as if they were underneath the Radiator. but it's all about preference and fan case fan configurations.
Great Vid!
Hahahahaahhahaha this fucking intro hahahahahahahaha oh my god haaha so so so so good jay your freaking awesome!!!
I did wanna go sleeping, but you have to upload a video, why jay? Wy u do dis?
Megaspasstpräsentiert HE is evil.
I'm glad I live in Brazil, it's 20:18 here :D
awesome video learned a lot today thanks .Especially since i am going to dipping my toes into water cooling my next build AIO mind you but still water cooling none the less and now i know how to place fans and Radiators now thank you Jay !!
A note, the PWM standard allow the control of LOTS of fans per header, so if you use a cable or breakout box that draws power from something like a Molex or SATA, but passes through a PWM signal you could run as many fans as you like off a single header (and indeed this can be a neat looking way to do things for cable management). The tachometer line is optional, and in theory shouldn't matter since all fans that comply with the standard will not over RPM even at 100% duty cycle (indeed this is the effective running state when the PWM line is not connected), although I have found some cheap fans may "tick" or otherwise adversely behave at the lower duty cycles despite the standard calling for all fans to work at the minimum, so if different fans are used I'd recommend connecting it to the slowest. The downside of doing this is you have less zones in which you can control speed independently, but using 1 header per watercooling loop is generally fine, as its cooling the same fluid, although 2 may be useful if minium RPM is a binding constraint (thus turn half the fans off at low load).
Use identical fans and connect the tachometer signal just to one of them. since all fans are build the same, they should behave identical and run the same rpm.
Lost a lot of weight Jay! :)
The pull method is easier to clean the radiator often.
So true. Compared to the push/pull I have now. Gotta take both fans and radiator off the case to take the fans off either side of the radiator to be able to really give it a good clean, sure duster through all 3 blows some dust out not near as much as I'd like :p
I do a push pull to my front mounted radiator, with 2 exhaust fans on top of case, and the 1 exhaust to the rear. Great vid
Looking back at some of your older vids. That was an excellent Arnold you did.
From 6 years in the future, this version of Jayz looks way too young. 2/5 would not time travel again.
Dat commercial at the beginning doe.
What character is that?
Lovin' the new intro. Nice and minimalist!
You answered my question about push & pull air into my radiator, whats good and what happens when I put it in front or put it w/the fan 😂. Thank! Continue more analyzing staffs.
I cool my watercooler with another watercooler!
Really like your videos Jay, but the commercials at the beginning are getting worse and worse...
Anthony B That makes you the minority! Have a nice day.
***** but that burn tho
Hello Mr Anthony, I will like to suggest to you adblock. Just search adblock on Google and install it. It will work withgoogle chrome as far as I know. Once you've installed it, anytime you watch jayz2cents, you have the option to enable or disable ads. In other words you can choose to not see them. I hope I have helped you today, as I didn't like jayz response to you. So you can get back at him by not giving him a fraction of some money.
Schmidt McGready thats not how adboock works
Schmidt McGready and it obviously doesnt block the in-video ad
Great intro and one of the best commercials i have ever seen. also great how to.
It was a lot of information, but very well out and explained so I was able to understand it easily. A lot of what I've seen before this was always biased one way or the other. I liked how you had a preference, but offered ALL the possibilities and explained how they differ.
dat arm flab
living the 370z life damn....:D
It's not a 370...
+UrNextOnMyList__ its a 350z lol
You could have like, told him what it was instead of replying like that lol.

he was tryna be cryptic
Haha for sure
Jay, before I can continue watching your video I have to say I'm so jealous of your car.
Nice videos, been on your channel a lot recently. I'm planning my first build, and I'm doing all my homework prior to submitting my orders. I was wondering, on a front mounted radiator would it be beneficial to push air out with the top fan and pull air in with the bottom fan? I'm basing this off the idea that hot air rises and the coolest air intake would be at the lowest point. I'm using the Fractal design nano s case, so the front is vented with a dust filter in between, and I plan on leaving the top side of case vented with a dust filter.
You copied their music.
Now convert to linux.
Or else.
Jake Whitton Or else he has to give free watercooling to all of his subscribers PCs :D
NeedMoreMushrooms Yes my laptop needs watercooling
Jake Whitton Linux is shit.
HowAmI yep
4:07 NO. Push/pull is when you have fans on *_both_* sides, not either side. Either means "one or the other" and that's not push/pull.
Its open to interpretation, people say one on either side, to indicate both sides. Makes perfect sense
Woww i haven't seen one of these kinda jay vids in 3 some odd years this is insane to see really i remember watching these ha 😂 great RUclipsr
Thanks for this video but how you control speed of fan with program or controller??
plz don't speek like a russian i have bad memories from dota 2 XD
