Hi, I am suffering from system crashes after installing an 8800gt and playing 3d games, I originally thought it was a power issue but I have installed a power supply which is more than enough to meet the cards demands. I have an 8800gt which likes to keep its fan at 30% no matter what. So I am trying to use riva tuner so that it runs 30% in 2d, and all the way to 90% in 3d.. even at 90% the core is 77c under stress test. However, I can only adjust the 3d performance in direct driver fan control.. and this makes the fan run at 90% in 2d as well! This is the same for fixed duty. When I try auto fan control the max temp setting is set at 85c... so the fan only auto runs up to 50-60% leaving the core at 85C.. Is there a way to change the automatic fan profile so that under 3d it will run the fan at 90% and in 2d at 30% automatically?Unless 85c is a safe temperature for hours at load? its a PNY xcerlate card. Thanks.
