Hey everyone, I've done an experiment that I think will be of interest to a few of you

One of thing with graphics cards is that they usually use more power than CPUs (often TWICE as much), but their heatsinks are not very efficient at all. The air is just recycled, rather than blown out of the case. There are some coolers that do vent air directly out, but they're usually noisy.
Add the fact that the space available on the side of a GPU limits fan sizes to about 90mm, things can get a bit hot and noisy...
soooo, I did this:
CPU cooler on GPU - YouTubeMy idea is that I can make a little compartment for the GPU (in a custom case of course) and have a fans at both ends making a little wind tunnel. The GPU can then be cooled SILENTLY. :brrr:
The max TDP of the graphics card I was usuing was roughly 170w, so this should easily work for higher wattage cards like the GTX 680 etc.
