Cooling SLI graphics cards for ~$10

post #1 of 3
Thread Starter 
Hey guys, i wanted to drop some knowledge.

I saw a pci slot cooler on ebay a few days ago for ~$10 and thought I would buy one to put between my SLI GTX 260s to see if it could drop the temps on my top card, and if it didn't i would only be out of pocket a few dollars.

As anybody with SLI cards knows, the top card always heats up by ~10-15°C above the lower card because it absorbs the heat from the other card (heat rises), so i figured this thing might help by pulling out some of that hot air between the cards so that the top card only has to deal with it's own heat.

The cooling fan I bought is a Thermaltake Cyclo slot fan, i found them on amazon for $13, but i only paid $9. It's a pretty basic design, an intake that can be mounted on the top or bottom pulls hot air in and pushes it out the back of the case.

For my experiment I ran MSI Kombustor 2.2 (Dx 10, AA 8x, xtreme burn in) for just over 5 mins with each configuration, starting the top GPU at 45°C each time with a constant room temp of 23.9°C to test the difference in the temperature of the top card with: No cooler, Cooler intake facing up, and cooler intake facing down.

Here are my results:

No cooler
700

Cooler facing up
700

Cooler facing down
700

As you can see the most significant drop comes when the cooler intake is facing upwards, which lowered the temps in the top card by 6°C, for only $10 I think that's a pretty impressive result, after a bit of cable management on the power cable of the cooler i managed to drop it by another degree.

Conclusion:
The Thermaltake Cyclo slot fan is a cost effective way to reduce the temperature of the top card in an SLI setup by ~6-7°C, with the fan facing upwards, and for only $10 I reccomend it to anybody having heat issues with the top card in their rig.

Good stuff- i have been eyeing one of these for a while, but wasnt sure if the cooler would fit between my lightning xtremes, since their blades protrude out slightly from the pcb and arent completely flush with the card

It's about 15mm wide, so if you have this space then it should fit. But the cards i have don't have intake fans where the cooler sits, only at the back of the cards, so it might not be as effective if it's starving the cooler fan for air.
