Putting CPU heatsink on the back of GPU (With fan).

[Destructotron]

My GPU is a Radeon HD 7770 if that matters, i would like to put a CPU heatsink with a nine bladed case fan (http://www.ebay.com/itm/290793195933) on top of it (Blowing down onto the card) maybe using thermal paste to put the heatsink on, on the area with the screws coming out (on the back of the GPU). Will this work?, will my GPU get damaged? Also, what would be best to keep the heatsink on the screw area?

I already posted this in a different section, but should have posted this in the cooling section.

Why would you want to put a heatsink on the PCB?

This must be an April fools....

No, this is a genuine question, and hopefully i can get genuine answers.

But still, why would you want to put a heatsink, and TIM, on a printed circuit board?

For cooling. Is there any other way to cool the GPU better from the back?, you aren't really answering my question. Is there a way to suspend the fan above the back of the PCB instead?, any answer is appreciated, thanks.

Putting a heatsink on the back of a graphics card will most likley short something out, and thats bad

If you want to cool the back of the card then a fan blowing air across it will offer some cooling but I wouldn't expect it to be a major benefit TBH.

But this is the sort of thing you could use as it doesn't have to be mounted on the card.
It can be mounted anywhere.

I have one in my case to help with cooling the slightly toasty northbridge.

But can i do anything with the fan i mentioned? (http://www.ebay.com/itm/290793195933). I have some ideas in mind though now.

You could fit it in your case.

Thanks, i have an idea in mind to get it to blow air over the card, i already have a side case fan though (Blowing out hot air out of the case) and also one in the front (Blowing air in to the case) and one in the back (Blowing air out of the case), i am afraid it might disrupt the air flow, will it?
