what paint to use? or no paint?

hi guys,

i'm currently considering putting some vram heatsinks on my asus 580 dc2 card. i haven't heard from anyone who has suffered vram problems with my card, but just looking at a naked vram somewhat worries me a little...

the story is i bought some aluminium vram heatsinks from arctic cooling, they're made of aluminium with no finishing paint.

now, my gpu pcb is black, so i kinda want to paint the heatsinks black as well, but i have no experience or knowledge in this whatsoever, so i would like to ask for your advice.

basically, what i want to know specifically is do i need some heat resistant paint or just normal paint will do? reason for asking is that i know the vram gets pretty toasty underload...

or, should i just leave the aluminium heatsinks as they are and forget about the colour?

thanks in advance!

thanks for the quick reply rheicel

do you think those will cut it? i know those are for graffiti primarily, they say it's for any surface, but didn't mention anything about high heat environment, any thoughts? or do i have to get paint designed specifically for metal?

Good luck with your project.

And like rheicel said "One coat should do just fine"
thanks for the speedy reply

so heat resistant paint, fair enough, it makes more sense but i just don't know where to get them, that's the problem with moving to a new country, LOL

hmmm...you reckon painting the heatsinks (if i can get a thin coat) would be at least a bit better than just leaving the vrams 'naked'?

OP, let me see the picture of that heatsink

yeah, not being a local doesn't help finding things...


sorry, a bit lazy to take an actual photo as my dslr takes stupidly high res pics then i'll have to resize it and upload...you get the idea

here's a pic i found on the internet, i'm only using the 12 small vram sinks top right of the pic



any thoughts?

http://www.thefintels.com/aer/homealuminumanodizing.htm check this out, but I wouldn't recommend it. Still looks like a cool project

lol, looks like a fun project, but doubt i'd be able to do it though!

thanks for the link nonetheless

I've had cheap paint chip already.

oops...

thanks, advice taken!
