Arctic Accelero Xtreme III on 2 GTX 580's SC overheating
Nov 21, 2013, 1:04 PM
I got 2 EVGA GTX580 SuperClocked running in SLI for which I got 2 Accelero Xtreme III coolers.
Ambient temp is 20-21C.
Using EVGA's precision tool to turn the fan speed of the card on top to 100%, I still get >95C in some games. The bottom card never reaches 75C which is OK.
The very reason I got these coolers is to have temp lower than 90-95.
I disconnected the fan cables from the cards themselves and connected them straight to the 850W power supply with the help of 4-pin Fan power adapter supplied with the coolers.
Now, both cards idle around 35-45C, but when I launch a game, the top one spikes to 90+ in a matter of seconds.
My question is:
How can I control these fans without a hardware fan controller ?
The pins from the coolers do not fit any fan slot on the motherboard.
Here's a picture of the power adapter:
Note that I have 2 of these connectors. One for each cooler.

I would remove the cooler and reapply thermal-paste. it seems like you're not achieving efficient thermal transfer to the cooler

Thanks for the reply.
I took out the cards and noticed that the cooler was not firmly tightened on the card.
After tightening it, the card on top never reaches 80C.
