I have a "EVGA 01G-P3-1372-TR GeForce GTX 460 (Fermi) Superclocked 1GB 256-bit GDDR5" and was wondering why the fan never goes below 30%.
This is an instruction on how to lower the lowest fan speed settings.
Download nvflash 5.100.0.1, and open admin command prompt in Windows 7 x64.
To backup rom:
nvflash --save backup.rom
Load this in Ultraedit, and for the correct address, I search "47 04 01 21 00 06 26 C4 09 20 00 00 22". The exact hex number you want to change is the hex address right after these. For mine, the exact address was 66d8h. Modify it to desired value, then save it. Ultraedit will automatically create a backup of the original as "backup.rom.bak".
Note: I tried hex number 14 (=20%), then also tried 00 (=0%). When I left it idle in Windows, using hwmonitor, the fan won't go lower than 15%. At 15%, the fan stays around 930 RPM. At 30% it was 1140 RPM. My room temperature is around 26C, and it's probably not going to go much lower than this since I can't stand cold rooms. So I set it at 15% for minimum value, which is hex number 0F.
To flash rom (2 steps):
nvflash --protectoff
nvflash backup.rom
