Home made cooling solution

[Whiptaka]

So my fan on my graphics card is all stuffed up and I need to do some image editing ASAP.

As a temporary fix, I read on a few sites that a standard case fan could be attached to the GPU's heatsink, to provide the necessary cooling. This may sound bizarre but it did yield some impressive results according to the okes who tried it.

My question is this: How will I attach the case fan to the heatsink, and how much heat can the plastic cover surrounding the fan withstand? Can I literally just let the plastic sit on the copper?

when transistor is fixed to a heatsink, you get a white grease that conducts heat between the 2.

Aluminum will conduct heat also well if place on your heatsink and heat will transfer to it.

You can begin by try and place a fan to blow over your heat source, if not good enough place a piece of aluminum stiff to heatsink and cool this whit your fan

I won't be concerned about plastic deformation of case fans with temperatures of 100'C or below.

A friend of mine simply used a glue gun to stick an 80mm case fan to his 6800LE which I bought from him a few years ago.
It was a mission to remove that glue, but it really worked well.
You can probably just cable tie the fan to the graphics card, but that could make a rattling sound if you don't use some form of rubber/silicone to damp cushion the case fan.

I won't recommend that you use superglue, because it doesn't like big temperature differences at all.
If you can screw the fan to the heatsink fins, that would probably be the best, but if the spacing between the heatsink fins aren't correct you'll have to resort to something else.

Just ensure that the case fan is blowing air over the heatsink and not sucking air away from the heatsink.

And check out the performance of the 80x80 fan on a regular basis - some doesn't like dust and tend to slow down over time.

Instead of putting the fan directly on the heatsink, you can position one or two to blow cool air at the heatsink.

If the noise bother you, try a 120x120 fan with an inline resistor to slow it down a bit. It'll move the same amount of air, but at lower revs, thereby less noise.

Thanks for the responses

I ended up gluing an 80mm case fan to the heatsink and temperatures are excellent . I just hope it lasts though.
