Thanks for your awesome thread!
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%, and found this thread.
I downloaded the two tools, NiBiTor, and nvflash.
NiBiTor v6.03 was complaining about "Cant connect to to service manager", it has two "to" in the message. Anyway, all I used was nvflash 184.108.40.206
in admin command prompt
in Windows 7 x64.I hope this serves as an updated instruction for others.To backup rom:nvflash --save backup.romThen load it in Ultraedit
, and for the correct address, I had to search "47 04 01 21 00 06 26 C4 09 20 00 00 22"
. It 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
I have a Lian Li Q11 mini-itx case with good air flow throughout the tiny cramped space. Here's my parts: Corsair builder series 430W 80PLUS power (added a resistor on the cooling fan), Core i3-2120, intel DH67CF, 8GB RAM, SSD, HDD, DVDRW.
