Why not approach your local university and get the engineering students to design heat sinks and then do comparisons/testing. Winning student gets a computer for their studies. Promo for Linus, Uni and sponsor company, wins all round.
That's actually a really good idea. +1.
because thats not fun. if you want something good, you go to the store and buy it. That's not the purpose of the video
too clever for them.
Oh gosh, I would love to do something like that. I am currently in my mechanical engineering masters!
Also on a side note, their project on the water cooling Room and PC's could have been so much better and cheaper, with a little advice by a real engineer. But I guess that would have killed some of the fun in watching the video, for some at least.
bene20080 and the consultation fee by the engineer?
Alex: "they cost like 80 bucks"
Linus: "and you were just ruining them??"
Also Linus: "you have a blank check"
@Bernardo Hagen At the end of the day this has nothing to do with him being wrong by saying check
Why are we talking about how Cheque/check is pronounced?
@Bernardo Hagen and it's your ignorance for trying to correct a word with multiple spellings.
Darth Nihilus they are filming in Canada as Canadians. It is cheque.
@@hunter1586 Holy shit shut the fuck up about, "Um, It's actually cheque 🤓." whenever someone replys to you about whether it's cheque or check. It means the same fucking thing, just spelt differently. If you're really gonna be a grammar cop, then you need to apply this bull to every word. Instead of using shit, poop, or whatever variations of caca is, you have to use the original. This is what I thought at the top of my head was so don't target this shit like your life depends on it.
I like how Alex is always smiling and laughing in every video like he knows a dirty little secret that nobody else does.
Ashish Jois
Well, He laughed at a dick joke.
Whoops, I meant sex joke, the actual joke is when you ejaculate in a woman lmao
6:27
Alex, Dennis and techlinked man are my favs
He is...
"You're paying me to do this."
I think we all know that little "secret"... I mean, come on. Come on.
“You can’t just slap a block of aluminum on the CPU, though.”
Pretty sure that was LITERALLY the end result of episode 2. It didn’t even have a fan except for a Corsair 120mm vaguely blowing next to it.

#aluminumSheetLivesMatter #heatpipeLivesMatter
Your comment is sketchy
Not as sketchy as that heatsink.
yeet
Welcome to the comments section. Where common sense goes to die
Note about soldering heatpipes: You can solder them, you just need to use a different type of solder. Personally, I use this stuff called ChipQuik, it's a different alloy that melts well below the explosion temperature of heatpipes. I recommend either a VERY powerful soldering iron or a pencil torch, heatpipes are hard to warm up by design.
That thermal epoxy is probably one of the biggest performance losses.
Also, heatpipe bending is easy, just a couple rules: 3x pipe diameter is minimum bend radius, this is to protect the inner capillary lining that allows the heatpipe to function. I recommend using bending springs and a template, that worked very well for me.
And an important note about heatpipe selection: Not all heatpipes are created equal. There are different capillary linings that are more or less effective and which operate in different positions. Sintered heatpipes are best f you're going to be in a variety of orientations, ridged heatpipes are horizontal only, but can carry way more energy because the fluid can flow faster.
Nice. I don't know what any of those are, but it's interesting.
@ 15:40 you cannot read the thermals from reflective metals, the emissivity affects the read temperature... stick some black tape over it and try again!
that actually kinda makes sense...
That heat camera is reading IR light (or heat waves) emitted from a surface, it can accurately read the temperature of a see through pane of glass.
98ahni - thermal cameras cannot read the temperature of reflective surfaces, the kind of surface effects the readings taken. Reflective metals are particularly prone to false readings, which is why they are normally painted or taped when readings need to be taken.
98ahni
Thermal cameras can't see trough regular glass only sapphire.
And shiny metals is like a mirror for it so you can't read the temperature on it, read the manual for any thermal cam.
Lol, that's exactly what my thermodynamics professor told me. I had never used one and didn't read the manual let alone think about how it worked. Seeing that I now know that it's based on blackbody radiation it's pretty obvious.
best video ever.
As a heatsink engineer with some workshop experience this is painful, but still very entertaining
i dont know what the right tools are, but i know that the ones they used were not it.
the pain.
Haha I was thinking the same thing
Where can i place an order for a custom heatsink?
If it works... job done... will people pay for it, eh.
Justin Clonts what was your first hint, the angle grinder? 😂
As a mechanic, my eyes are bleeding while watching you guys doing all rhis stuff xD but soo funny 😀
I’m not a mechanic but my eyes still bleed 😆
Bro im mechanic too!!!
@RexTech thanks bro i earn a lot of money i need to find a Big booty gymshark girlfriend now
@RexTech im mechanic on amazon mechanical turk
I'm pretty sure that bench vise is not supposed to go on a drill press 🤔
It's awesome to see how far Alex has come. He was incredibly shy when he first started. He's come out of his shell in this video and as of 2021 he's a great host filled with confidence. Really nice to see a smart guy like him doing so great :)
Alex shifted his menace vectorand instead of being a menace to himself, became a menace to his cohosts.
Swear to god, there's either a Frankenstein or Ivo Robotnik inside his head.
"you had a blank cheque to get the tools you needed" some time later... (Their mega workshop vid)
That's what happens when you tell somebody, on camera, that they had a blank check. They say "Ok, Then let's DO THIS!" That's what I would, do anyway.
The execution of this reminds me of Top Gear making a convertible people carrier.
I loved that episode
What about hammerhead eagle I thrust ?
@ ooh yeah, I remember that one.
Linus Tech Tips: Ambitious but rubbish
Man now I really remember why I miss old top gear. If it isn’t Jeremy Richard and James then it ain’t top gear.
Woah woah throw away those grinding discs you used to grind on the aluminum right away. You never use regular grinding discs on soft metal such as aluminum. The metal can get embedded into the disc throwing it off balance and spinning at 10k-15k rpm will cause it to shatter throwing shrapnel everywhere. Also becareful placing the grinder down on the disc. The same issue can happen if you smack the grinding disc into a hard surface. Had one guy at work split his guts open because the grinding disc exploded.
Woah that's serious
Don't forget that balanced operating range is way different than unbalanced one, vibrations are a bitch and destroy everything you can imagine
Those were aluminum cutting discs, we're not a fan of potential disc explosions either.
I saw the consequences of an exploding disc too when i was at a hospital. When I asked to the people who brought them they said he was working on some construction thing and the disc exploded on him, the poor guy had his abdomen open side to side and his intestines were practically hanging out of him. Angle grinders are a really powerful tool that needs a lot of respect when being used.
Alex is a very practical man with a nice name. I like him
Agreed.
I love the name Alex too. It's my husband's name. But I also agree that smile and also he is just a big cute softy...
As a professional machinist I can appreciate just how sketchy this is.
I'm surprised they didn't break a drill
Right think we all have bodged something in the shop just to get it done. I still have a ball pein hammer I made from scrap cause someone stole mine out of my box.
does one get customers first in order to afford tools? and how do you get a place? because a place is so expensive.
@@snorttroll4379 It is a catch 22, usually you make money working for someone else, and if brave enough you use those savings ( plus a loan often ) to start a business.
This guy is to Linus what Linus is to literally everyone else when he's doing his own thing.
You mean worse than Linus? Okay. And Linus is certainly a worse hobby machinist than many of us here.
I absolutely love coming back to these videos of Alex, especially comparing them to his more recent works
Exactly why I'm here atm
This is the video that you watch in shop class for examples of what not to do
BRNKoINSANITY All that yummy aluminum dust
Yeah lmao
Oh hey BRNK!
As a fabricator, this is painful to watch.
I laughed when they said they can't solder it. Because i often solder heat pipes in laptops with a torch. Though soldering aluminum with torch is really tricky.
And they can't even cut aluminium by hand.
Agreed
Thinking the same
I honestly can't understand why they pay him to do this shit... Is it... is it supposed to be entertaining? The way he fucks up every single thing he touches?
Every DIY project Alex does is fascinating. These videos are the perfect blend of thoughtful engineering and fly-by-the-seat-of-their-pants chaos
This video is a great illustration of why machine shops exist lol
They used the hell out of that drill press though
It's like watching a modern version of the Red Green Show. Remember Alex, if the ladies don't find ya handsome, they should at least find ya handy.
LOL!
So early, it's still 360p
same
2 Minutes later and it is still 360P
In The Mind of Kibara same
Same :/
In The Mind of Kibara Still 360p, fuckin nasty
Linus: "I approve everything you want to buy!" Also linus: "You spent money on GOOD QUALITY HEAT PIPES??"
You need to contract AvE to do this !
AvE and This Old Tony, these guys at your back you might have a product.
Also Alex French Guy Cooking to knock up some Brain food.
that would be fun
yea uncle bumblefuck needs to be on the case
Then they'd have to call it 'skookum heatsinks' as opposed to "sketchy heatsinks"
I was just going to say they need AvE!!
As a kid with no machining skills at all. This is painful to watch.
Not a kid and not exactly no machining skills, but very minimal, and yeah i think i could do a better job on the machining par.
@Advocatus Diaboli lmao no

@@Ferotiq argeed
As an active machinist this is completely painful to watch. However I do have to give them some credit on the fact that they did a lot better than I expected.
You know you're dealing with professionals when the angle grinder has a label "angle grinder" on it.
That's how you make sure it's the workshop angle grinder.
You shouldn't use bedroom angle grinder in workshop
@@nandulalkrishna923 Exactly! Sometimes I find my roommate using the kitchen angle grinder in the workshop. Thats gotta stay sanitary, dumbass!
@@thekingoffailure9967 I die a little inside whenever my housemate uses my fabric angle grinder on paper
There are people who work at LMG who don't know or don't have any experience with an angle grinder, so that label is there for them. So in situations where someone asks another person to fetch one they don't waste a whole butt-ton of time looking for one.
i would have bashed Linus if he did the video entirely, but watching Alex getting proud over nothing and his shenanigans is enjoyable even though the heatsink sucks
"Heat pipes will explode when you... Heat them".
That voiceover tho... Crispy documentary mode
Yea that needs to go
This needs an update, what with their new CNC and better experience at working with heat pipes...
Just cut a potato in half and set it on it. It probably has some thermal capacity.
DesolatorMagic and you could eat it after the PC shut down
Make a V shaped cradle for the potato out of heat pipes, wrap the potato in foil, and when you hit thermal throttling, hot swap the potato for a new one wrapped in foil.
Or set up a mini spit roast and cook some rats...
Now that you've gotten all of the correct equipment, are you going to do another?
I'm really looking forward on this
*Step 1:* see someone complain about not having something they need/want for their job
*Step 2:* see them get a "wtf mate?!" look from their boss as they say they always approve their order requests
*Step 3:* dream about working for a boss like that
When I say "hey we need to replace this hard drive, we only have 1 safe failure left" i get told we don't need to get another one then and that I need to 'make sure the other one doesn't fail' -.-
Frosty. Your boss sounds special
True story, tell me about it...
Boses always say that... On camera.. Off camera it is another story, which is why the stuff is never there :D
I miss scrapyard wars. It would be interesting to include Gamers Nexus.
It's coming soon.. This weekend on floatplane I think?
Aniket Bhat oh boy if thats true you just made my week
cough cough its on floatplane cough cough
Pretty interesting to see the progression of Alex. Nowadays he creates professional mechanical engineer level drawings in Solidworks, does amazing CNC work, and designs everything with a great level of forethought (even if on-the-fly). Nice to see that advancement
You guys should really buy a small CNC mill. You could make all kinds of things. The right way! haha I can only imagine how many machinists are screaming at the screen right now. But I guess that's good Tube.
Even an old vertical mill with a digital readout is better than what they having right now.
BurninatorTheTrogdor **SCREAM IN TEARS**
I died on the inside watching this
Naw, then you have to learn how to talk machine. It's a pain in the ass. Any old milling machine (with what will said, a DRO)would have provided a much, much better alternative to what they were doing.
why is this not called Alex Tech Tips?
Tacolord because Linus is the one that started the channel 4+ years ago, where Alex had only been here for a year or 2
you must be fun at parties
Also because the credit always belongs to the person who had the idea and not the one who executes it.
Why is this not called Heatstinks?
Alex Porn Tips
4:42 Even the police got pissed off for hammering the bolts in...

Wait that was a screw? Why were they hammering it
Titan Blade Nazi resolved.
AnonyGuy that's... You've watched LinusTechTips before, right?
Sketchy PC modder police
I think we should all admire at how far Alex has come over the years. He went from this... thing to designing water cooling blocks at industrial level quality.
Alex, just buy a milling machine. The hacksaw and the angle grinder are far from the ideal tools for that job.
I'm sure Linus will pay for it.
Any old milling machine from the 80s and some of the 90s that is sized for small projects would be cheaper than their red cameras. The biggest issue would be the 3 phase electric bill and carbide or hardened tool steel bits for them. Also the amount of knowledge needed to operate one without destroying their bits every 30 seconds because they have rpms cranked to high or low.
hgrinc.com/productDetail/Machine-Tools/Used-Bridgeport-CNC-Vertical-Mill/06181090010/
Or just a bandsaw, this is pretty basic stuff.
Aaaaand that's for the next episode. The finale would be getting all the proper tools for the job... BUT IS HE GONNA?
They don't necessarily need three-phase and old iron, they could get a Sherline or a similar hobbyist machine. Though yeah, they'd probably want an actual machinist to come by and explain to them how to use it without getting shrapnel in the aorta.
Linus: you had a blank check to work on this! you had no excuse!!!
also: I would approve anything you would need for this, as long as you order it!!!
alex tho: if only we had (tool/this material/ whatever they needed atm)
linus: *lolwhut?
maybe he got used to complaining and not getting the stuff he needed back in engineering school...
0:09 Linus: it was over time over budget.
1:12 Linus to alex: you had a blank check.
Blank check but over budget.
Linus = liar
As a machinist in my past life, this was painful to watch lol.
This series definitely needs a revisit once the LTT Lab is up and running
Why use the flir to measure aluminium temps? You're measuring reflections. I have the same Flir and measuring shiny parts just doesn't work that way.
Pro tip for LTT. If you want to measure the temperature of something FIR reflective, like a block of aluminum, put a piece of electrical tape on it.
I miss those sketchy old project 😂
I dont think Alex get enough credit for what he does, give him so more time to perfect it and bigger budget for parts... I think if he sticks with this design and work on it he can make it better then evo...
Александар Кнежевић he literally has a blank check
To buy what ever tools he want, he had to be on the budget for materials since that is what they compared at the end... What they didnt count in is R & D that those companies spend to produce those product witch he didnt have...
Imagine how you feel when you are working, and your boss is always watching beside you!!!! That's how things get messy...
This makes me feel so much better about my current project.
Why not just use pop cans? It's already THIN and made out of aluminum right?
Oh god, that would add to the sketchy look for sure! I say it's a good idea.... Like 100 layers of can side all wobbly and wavy on the heat pipes. Would look way more ghetto, and may work better if the layers were close enough and air still flowed.
the inside of the can has a coating to prevent the drink from leeching metal and tasting bad. probably not great for conductivity
steel wool would be perfect..
error 102 I hope you're kidding, the reason we use thermal paste is because air is a horrible conductor of heat, and I wonder what is in all the crevices and gaps of steel wool....
I think he means steel wool to brush the coating off, not to use as the heatsink
Linus Tech Tips Slogan: “Good enough”
8:56 wow ,amazing continuity .nice haircut .
you know, the video was funny and all, but honestly you learned a TON about fabricating aluminum by doing it with weird and sketchy methods. I mean everybody first tries that stuff, but then next time you say to yourself "hmmm that was real rough last time. there has to be a better way! let's try doing something different..." So now you understand many of the processes at play. One word of caution, be very careful with large gardening-style gloves, don't get too wound up in your work.
Alex is such a majestic being
Hey guys, some tips for your safety and to make life much much easier. When cutting aluminium with a friction type disc, get a block of bees wax or bees wax candle and apply it to the disc. This lubricates the disc as alum gets quite soft when hot and grabs the disc which risks it exploding in your face. Second when drilling materials a simple rule of thumb, hard material=slow speed lotsa feed and the inverse of course soft materials =high speed soft feed and if your drill squeals its rubbing not cutting. And 3rd when you are cutting profiles in materials like the cpu mating plate, a jigsaw with the appropriate blade will be a godsend. Happy fabricating lads
You can't read temps off shiny surfaces with FLIR, put some masking/electrical tape on it first and read the temp of the tape surface
Jessica Taylor tape can be kinda reflective
@@daeyvidd Masking tape is not reflective, you moron.
@@ChristAcolyte to be fair he did not specify which type of tape could be reflective didn't really need to call him a moron
@@AstroKitty16 is this a blanket statement or is it relevant to my comment? I don't
understand.
Advocatus Diaboli normal yellow masking tape is thin enough that it doesn’t skew the reading, whatever time it takes the cooler to reach a stable temperature will be more than enough for the tape surface to have the correct temperature to measure it.
Heres a Better heatsink : Use old intel stock heatsink center core wich was pure copper shaped like a tall puck. Drill 4 holes vertically on each corner and incert the heat pipes With the same bend you guys used but pointed away from eachother. For the cooling fins you need slightly thinner aluminum.

Any one else love how at 6:46 thet've labelled the saw?
That's so when they ask someone to get the saw, there's no confusion as to what it is they're meant to come back with. .. ....
I have the impression that the angle Grinder is your preffered Tool of engeneering ^^
I like that
"You had a blank check to buy the tools you needed"
*Alex buys Noctua*
Unlimited budget... goes for cutting down 4x4 instead of the needed 3x3 (or getting the shape you actually needed laser/waterjet cut) because its cheaper... SMH
I mean, and this is by no means hate at all I love you guys, you have to admit that the end result is pretty impressive after watching how you use the tools etc 😂
Good lord LTT, please buy a Dremil. It'll give you the precision of a hand saw and the speed of an angle grinder.
Samuel Bianchini until Linus dropped it and didn't catch it on time
A Dremel wouldn't go through that thick aluminium block unless you have the patience to cut for hours on which makes it as fast as handsawing that block. It would work fine for the thin sheets though
A Dremel doesn't come with an operator who has a clue.
In These Comments: Self-important 'machinists' not understanding the premise of this video series.
TeddtheTiger while that’s somewhat true, even being a non machinist, but avid DIY'er, some of the things they do makes me cringe... For instance wearing gloves near a drill-press is a good way to loose a finger...
Sure it’s entertaining to see them fumble with things to a point, but with the material they had, and a little more though beforehand, like planning the layout of the heat pipes out before they went for it, or actually drilling with some measure of accuracy, the end result could actually have been a fair bit better with little or no more cost, and actually less time, if they had some experience with using tools, or had someone help them just a little...
@@RandomName100 u have a point mate
If I did something professionally, and I watched two kids do the same thing very poorly; I'd also chime in with my 2 cents.
@@RandomName100 Nope this is grammar Nazis all over againe
But is it better than an AMD stock cooler?
Zecrid no.
Zecrid of course not XD
Yes, before ryzen came out
Is that sarcasm? I mean amd stock cooler are way cooler than Intel's stock cooler.
Cooler.
my old amd phenom 2 with a stock cooler and a case fan in the side, back, and front would overheat and shut down my pc playing some games; my significantly faster i5 3570 with its stock cooler and 0 functional case fans in the same case both ran cooler and did not overheat... that's how bad the amd stock cooler was
That was super painful but I’m happy to announce that I finally got through 19 minutes and 5 seconds torture successfully
I'd love to see a comparison between the real Hyper 212 or similar, compared to the clear rip off versions on eBay
We need another episode like this in 2021!
Do they not have shop classes in Canada? This was painful to watch....
not everyone gets to learn to use tools (unfortunately)... Kind of suprised he doesn't seem very experienced with the saw and disc grinder, considering he apparently has some experience in diy buggies.
I've come to this late. Induction shrink fitting is a better solution than thermal epoxy if you can machine to reasonable tolerances and do the calculations re thermal expansion. Rather than bending heat pipes, you could possibly use LOTS of vertical straight ones. Spacers made of low thermal expansion materials between aluminum fins would help too whilst the thing cools down.
An all copper solution should be possible.
Use of high copper amalgam is possibility instead of thermal epoxy, but local laws can be very strict about use of mercury.
I so wish I could work for for you guys just to stop you from doing shit like this. Get a mini mill!!! They're not that expensive and you'll get tone of use out of one.
Adrian Gonzalez They know we love to watch them fail. Why mess with that?
EHEH RON another thing for them to ruin xF
Them. On a mill. simply deadly
would be cool with a revisit to this now that you have the CNC mill
I know this tool is surely long gone but that laser is user adjustable so you line it up once you set your bit in the first time. After that it’s good to go until eventually it gets knocked out of wack again
I would love to see a sketchy heat sink made of pennies.
Benjamin Boone I once had a laptop with an extremely anemic heatsink. They used a thin aluminum/copper shim to transport heat from an ivy 3317U to an anemic fan 3-4 inches away that doesn't have fins (Asus x202e). Odd how the Pentium models have heatpipes and fins though. Anyhow, I taped pennies on the heatsink so it can absorb more heat and soldered some diy fins in the fan by using those bendy metal things in paper folders. From thermal throttling at 10 seconds it went to 1-2 minutes and you can actually feel heat leaving the fan.
Has been done ages ago to fry an egg on an Athlon XP - kind of. Not pennies but actual copper coins and no word on CPU temperature.

I just got a add where linus is the add LOL
EnArDee you idiot, it’s ad not add.
think the heatpipes you used are like half the length as they normally are going all way from top of heatsink and curve around the block and back up the other side with the whole bottom of the pipe as part of the block mating face. thats why a 6 heat pipe cooler looks like it has 12, they are a big U shape
Me watching this video "hmm hyper 212 sounds pretty familiar". Looks over to CPU cooler in box "heeeey". It was the first part to my new PC to come in, everything should be here by next Friday! Can't wait to see PC gaming in person!
All y'all machinists better look away.
Content contains abuse to tools.
*flagged for violent or repulsive content*
Take 1mm copper sheet and 1mm aluminum sheet.
Cut a number of fins, mixing tall aluminum fins and short copper "spacer" fins.
The cuts, probably best done via a stack up and Wire EDM cut for consistency, need to include a couple of holes, into which copper or aluminum bolts can be ran through to tie it all together and create a sandwich.
If the fins are designed correctly, it might be easy to include a way to mount the heat sink to the motherboard and attach a fan to that as well.
As a physics student, I see so much room for improvement and so much bad guesses about the thermal conductivity.
Alex the type of person that lies on his resume at the job interview
You should make a heatsink that is just made of thermal paste. Take one of those old coolers that had a copper slug, remove the copper and fill the void with thermal paste.
