Solved Arctic Accelero Xtreme III on 2 GTX 580's SC overheating Tags: Cooling Graphics Last response: November 22, 2013 7:30 PM in Graphics & Displays Share puya136 November 21, 2013 1:04:44 PM First post. 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: http://i627.photobucket.com/albums/tt359/puya_ro/connec... Note that I have 2 of these connectors. One for each cooler.

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. m 0 l Can't find your answer ? Ask !
