Cooling the back of a video card?

[GasX]

Any suggestions?

I suppose you could put on a heat sink, but how do you attach it without short circuiting the board?

any particular reason why you would want to do that? :frown:

 

[lotust]

the reason is beacuase it gets dam HOT.


Mwilding,

you can use ceramic material. it will work to glue a heatsink on the back. I was gonna try thin on my Gforce 256. But I cant find the material anywhere. + im too cheap to buy it

120mm side blowhole works wonders! Or how about this: spray the back side with several coats of clearcoat for electrical insulation, put a big blob of Radio Shack heatsink compound on, and set the heatsink on it. Maybe attach the heatsink with a ziptie. Or if you don't mind spending some money, pick up some non-electrically-conductive thermal epoxy and use that. Brush on a thin coat and let it cure, to serve as an insulation layer, then attach the heatsink with more epoxy.

Keep in mind that video cards run hot these days. I seem to recall ELSA having a special utility for their GeForce 1 cards that would underclock the GPU to cool it if it exceeded 100 degrees Celcius. That is 212F! Obviously the chips are able to take a lot of heat without suffering damage.

My card gets as hot hell, too. But I havent had one problem with it. I say if you arent having problems then leave it as it is, unless you are really set on cooling it.
