Powdercoating Heatsinks? --Yes/No?

post #1 of 12
Thread Starter 
Well, the new TRUEBlack and all the comments on the powdercoating affecting the thermal propeties got me thinking!

Any thoughts on taking a regular cpu heatsink and getting it powder coated?
Or, even taking the extensive NB/SB "Cu" heatsink off of a Maximus/Rampage and powdercoating that black!
I really like the look of the Black setup on the new Maximus II Formula P45. but, would rather stick with an X board.
Thughts?
Anyone?
CD, Your input?
I think it would make for a truly unique Mod. "Black on Black"
Cheers

On the same thought process, you could also anodized aluminum heatsinks for a more metallic look.

I would assume that the powder would insulate the heatsink. How much, I don't know. I think it would be fine for NB etc., but I would think twice about doing it to my CPU.

Sorry a little off topic but been meaning to make a post about this, would painting my Tuniq Gloss black with Engine paint make my temps worse? or no effect???

Isn't powder coating quite thick, maybe spray paint would be a better thermal alternative because it's thinner? I don't know, seems like a cool idea to have it all black though

Engine paint is made to withstand heat, not to conduct it. I think it will effect temps, but not by a whole lot.

yeah Engine parts/design and made for withstand high heat, cant compare....

my guess is powdercoat or any kind of paint will reduce the performance, just a matter of how much?

The engine on my motorcycle is powder coated and it gives off heat fine.

Seriously I have wondered this myself since I wanted to do some powder coating to a few parts going in my current mod. I do know it is pretty thin though. Maybe thinner than a couple of coats of paint, but not by much. I can ask one of my friends that does powder coating to see if he knows...

Yeah, but it was also designed to run that way. (assuming it is factory) Is it liguid cooled? Is the rad/oil cooler powder coated? Also, your m/c engine is deigned to run at a certain temp and not simply as cold as possible like a CPU.

I dont know for sure but I think painting a cpu hsf with engine block paint will have a large negative effect on the heat dissipating out of the fins. Since that paint resists heat, you are probably in effect creating a heat resistant "shell" on the hsf. the heat can still flow in through the base and up the heat pipes, but now cant as easily flow out to the exterior surfaces of the fins.

just a theory how ever
