Flashed my gtx570 bios to lower minimum fan speed->why was this limit there to begin with???

post #1 of 3
Thread Starter 
I used the guide and software found here:
http://forums.guru3d.com/showthread.php?t=336117
to lower the minimum fan speed for my GTX570 GV-N570OC-13I from the standard %40 to 0%. The reference bios for the gtx570 limits the fan speed to %40 minimum. Why? Before the card was too loud for my tastes while idling at %8 fan speed and now it's much quieter and is still only 33C. I don't get why it was locked to begin with, but oh well glad I found the fix...

What are your temps like? The limit is there to stop you from cooking your card.

I didn't hard code the fan speed, just allowed the bios to allow program controlling it to let it go as low as needs to maintain temperatures. If I game the fans ramp up so no matter what temperatures are fine, but it idles at ~33C with %8 fan and is very quiet.
