DIY heatsink for your video card

I haven't tried this yet but I'm sure it'll work for anyone on a budget.

If you have a large video card like a 9800GTX, all you have to do is take off the stock encloser and place a fan over the heatsink. The heatsink is made of copper so the only thing keeping it hot is all that heat trapped inside the plastic casing.

Eh, that will help some, as long as the VRMs are still getting air. It is still quite a bit more effective to use a much larger heat sink like the S1 rev. 2.

Of course, now all that heat being generate by the card is now circulating inside the case, instead of being exhausted directly out the back.

That's going heat up your system quickly unless you speed up your other fans to compensate.

Placing your own fan over the cooler won't really cool it very efficiÃ«ntly. The fan used normally moves the air perpendicular along its axle, while a normal fan does not. The heatsink is built in such a way that only air that flows towards the backplate of the card gets optimal heat exchange.

Next to that, stock heatsinks perform lousy, because they cannot remove the heat from the core effectively enough. Only heatpipes can do this nowadays. The fin surface area is quite low on stock coolers, and they aren't built on passive/low airflow operation.

For someone on a budget: just get the accelero rev. 2. Thing costs 10 euro's or something, and cools a lot better than a fan mounted over the heatsink...
