- There is a lot of thought put into Heat Sink design. They are fascinating pieces of metal. If you have any questions leave them in the comments below and I will do my best to answer them.

My mind is blown away how much science can make simple things work so complexly.

I had no idea the pipes on the heat sink were so...engineered. I thought they were just copper tubes! Thanks for the informative video.
They are known as heat pipes and will often contain a liquid coolant which will change phase between liquid and gas
Love your voice for instructional videos keeps my caveman brain at ease when i struggle to understand things lol
Thanks
I am a very curious fellow and I thank you for such an in-depth explanation of how a heat sink works. I truly appreciate my NH-U12A as my temps were around 75-80c under load and now they are well below 60 with the cooler.
Thank you! Finally understood how heatsinks, pipe works.
definitely subscribed… your channel needs care I really appreciate your work and content and I hope your channel blows up
Great job
doodelay Thanks
Very comprehensive explanation, thank you.
stg I could've counted those f**kn fins if you didn't move and cover it so much bro. Thank you so much for explaining this though honestly. very helpful.
Who's here after the PS5 teardown and to understand a little bit more about heatsinks 😂🤔?
me, lmao
Pachinko it didn't help me alot tho 🤯😂🤷🏼♂️
Bro me, I saw the big ass heat sink and I was like I wonder how that works 🤔lol😂
Yep.
would be cool to see this in action with a IR camera
To dumb it down for people quickly, the heat from the processor conducts to the fins of the heatsink, and the fan blows through the fins cooling it. If I missed something or got it wrong, please correct me! I've only had a few years of science classes.
Excellent. Well done. Thank you.
Great explanation
So, long story short..
The heat from CPU goes to the base metal plate (made from coper in this case) wich then spreads to the radiator looking thing.. wich also has a medium size fan atached to it wich then blows wind to the radiator to faster blow away the disipated heat from the radiator.
Great video - thanks for posting!
Thank you so much I loved this vid
I disagree on conduction being superior to convection. It depends on the specific implementation of the cooling system. If you mean conduction is better than hardly any convection at all, like in your frying-pan example, then you're right. However, if you force the convection just a tiny bit, you get much better results. Convection is the reason water coolers are superior to air coolers, as it makes it possible for the heat to be transported away from the CPU more quickly. Yeah, in theory you could make a three-metre tall passive cooler with ultra-thick, solid-diamond pipes and diamond fins. That would beat the water cooler, but at what cost? But then someone would come up with a new liquid-cooler design that would move ambient-temperature water next to the CPU at a flow rate of 10 litres per second and would beat your diamond cooler at a fraction of the cost. Also, it's the steam inside the cheap air-cooler pipes that moves the heat away from the CPU by convection, and it's convection forced by the fan that pushes the heat away from the fins. So most of the heat transfer that occurs in air coolers is done by convection.
You don't even need that much overkill to outperform water cooling, big heatsinks with big fans that fit inside a computer case trade blows with water cooling and beat it in cost/reliability. The only thing water cooling has going for it is the huge amount of mass you can have inside the recipient and distribution blocks in a custom loop, that will delay thermal equilibrium and beat air cooled temps for longer. But leave your computer rendering and 30 min to an hour the temps will equal an air cooler.
Great video man
Very informative. Thanks❤️
So much respect dude🖤☹️
Awesome video
Really interesting intro for a beautiful piece of engineering. Tell me - can I use this heat sink device on board my small boat with 12v system for the dual purpose of 1) excess power dump for a wind turbine (in combination with a DC converter / charge regulator), and 2) as a means of heating the cabin (ie. background heat to take the edge off cold winter days)?
You would just need to size a resistor for a load dump, however any power generated by wind turbine would be quite low and probably not enough to heat the cabin meaningfully. The resistor would also need to be properly sized for the load maybe PTC would be better as it is self regulating . Either way not a good use case for these types of heat sinks
I have some stupid questions if you guys dont mind :) What if I have a small wooden box, 100x85x25 inches. Would I lower the temperature inside the box if I just put a 100x85 inches aluminum heatsinks for LEDs under and on top of the box and cool them with a fan? Also, can you lower the temperature inside a closed kitchen cabinet or drawer using heatsinks and fans and no air flow to the outside? I need like 5-10° celsius for both cases. Should I buy and experiment or its just not enough ?Thanks
AL DEL I dont know how to answer this. However, if you cant find an answer online I’d check out different PC threads on Reddit. Normally they’re very helpful.
Awesome Vid
Hi. Does the fan blow air into the heat sink? Or does it blow air away from the heat sink?
You want the fan to blow air into the heat sink. some heat sinks can have two fans which then you want a push pull configuration where one blows air into the heat sink and the other blows out
did you Buy Heat sinks just to make this one video or there left over?

@@TheNuclearPinball Well, Now I know.
What is the best between Copper and Alumunium base? (Sorry my english is bad, so i can only understand half)
Copper maybe slightly better, however the gain is probably lost in the noise.
@@TheNuclearPinball thanks for your answer.
Hi. Can a heat sink work in a vacuum?
I know your comment is 3 years old, but yes a heat sink can work in a vacuum (which is why the ISS has heat sinks) However, because there is no air for convection, it can only transfer heat through radiation which is far less efficient than convection dissipation. So you’d want a coolant to act as a medium in place of air.
@@jakesheldon7637 wouldn't the coolant just keep heating up because there is no air for the heat to transfer into?
Great!
Good.
Super
ok where is this soonngggg?????
Do all heatsink pipes have water in them?
There has to be a working fluid, water is the most common.
@@TheNuclearPinball cheers man, most insightful! Very interested in the workings of heatsinks, especially on how it's implemented on cooling gaming consoles.. found your explanation to be concise and easy to understand :)
Mcnasty 😳
so basically its just a mini version of a car cooling system
Nope, think of heat pipes as just a heat highway. It is just a way to move heat very quickly over a distance. A car AC must add some work to compress the gas to turn it back into a liquid. Then it must cool it and evaporate it to get the cooling effect in your car.

whos here because of PS5?
What I don't understand is based of the way you explained it, it should work optimally! But off this detailed review, its mediocre. Why is that? You seem to have a deep understanding of how it fundamentally works, why would someone say its basically... "whatever". is there any room for improvement? www.overclockers.com/arctic-freezer-13-pro-co/
wrathoffufuke I would take these reviews with a grain of salt. Most tower heatsinks have the same design but the quality of material can also be a factor. The world of computer cooling is full of Marketing misguidance mostly because it can be difficult to measure the actual performance or if the extra performance is required. There is always room for improvement but that always comes with a cost. Hopefully this helps
You need to try your best to speak louder. Why are you whispering?
Sounds pretty good to me.
