Hi there, I'm kind of speaking on behalf of a lot of people here so any help that I could pass on would be much appreciated! Juding by Blizzard's forums, many people who play World Of Warcraft are experiencing major problems with ATI cards - total system reboots, locks and/or crashes to the desktop seem to be commonplace. I've heard that similar things also happen with ATI cards when running Doom 3 and Call Of Duty 2, amongst other games. I am running a Radeon 9800 Pro and have tried everything to correct my crashes - sometimes I can play for hours with no problems, other times the game will cause total system reboots every minute of play. I have introduced more cooling into my case, checked my RAM and power supplies, even tried running the game in OpenGL and with hugely reduced detail levels etc etc, all with no change. A lot of ATI users are in the same boat as me, so I decided to try ATITool in an attempt to rectify my problems - someone suggested that resetting my card's fans to dynamic control might do the job, because apparently all ATi Drivers since Catalyst Control Center was introduced explicitly turn down the video card fan speed due to customer noise complaint. I have also downloaded an alternative interface for tweaking from http://www.omegadrivers.net/ as I was told that disabling VPU Recovery might help (it hasn't). Was just wondering if anyone can tell me how to change the fan speed for my card using the tool? or if anyone has any other suggestions? Many thanks in advance for any help!
