OS: Windows XP sp2 Video card: Evga 8800 GTS 640mb Video Driver: nvidia driver 169.21 When using Riva 2.09 and setting up fixed fan profile everything works fine, but when using Auto the T min does not stay at what I set it. I currently have my G15 lcd display ( ) several things about Riva and one of them is my Fan speed %. Power user setting RivaTuner \ NVIDIA \ Fan - AllowBinaryFanSpeedControl: 3 Low Level fan control settings for auto: Duty cycle min: 60 Duty cycle max: 100 T min: 45 T range: 20 T operatin: 110 T low limit: 110 T high limit: 110 But these settings only stay for a few moments then the T min starts to creep up, for example if I hit cancel and go right back in.. the T min says 46, then hit cancel go back in.. it's 47.. but the rest of the settings stay the same. I tried using the excel sheet from http://www.vaguesoft.com/index.php?pageid=rt207#g15 to make sure I wasn't putting in invalid settings.. eventually after some delay the T min reverts itself back to what the default nvidia? setting is thus the video card runs way too hot for my taste and eventually causes issues cause the duty cycle min doesnt keep up. I've tried toggling the 'Restore fan settings after suspend mode' and 'apply fan settings at windows startup' but no changes. After writing this post I just checked my T min and now it shows it at 49.
