All bios programming software has min/ max fan speed. If u want cool set a high min but it will be loud and it only goes to 100% at 105 Celsius so you have to use EVGA Precision X for the fan on anything made after the GTX 200 series. Kinda sucks I loved the fanspeed ic on the gtx 200 series cards. If you want I can mod your bios to get huge performance gains out of the gtx 465 chip. We can push to 835-851mhz core clock territory. I can't wait to setup my 896 cuda cored 851mhz gtx 470's in sli for cuda encoding only.
