| 668418 | 2008-05-12 02:12:00 | I have bought a new case fan - it's cooler BUT it sounds like a vacuum cleaner :groan: (seriously) Runs at 2500RPM - too fast and too loud! I have successfully slowed it down using SpeedFan (to 40%) but I have to launch speedFan and slow it down again after a reboot . Is there a way I can slow it down on boot? Specs below . EDIT: Being powered by a 3-pin connector on mobo . |

| 668420 | 2008-05-12 03:44:00 | some fans come with a small inline resistor that can be added to drop the speed, I don't know if you can buy them seperately though. The fan will have either a current or wattage rating so if you felt adventurous you could work out the resistance and buy a resistor to suit and insert it in the +12V wire. A 0.8A fan for example works out to about 15 ohms to half the voltage. A cheap fan controller is simply a variable restor with a nice front panel. Some more expensive ones could possibly use pulse width speed control. Or just buy a slower fan. |

| 668421 | 2008-05-12 03:45:00 | p.s. some ASUS motherboards, and possible others, have an option in the Bios to control the fan speed based on temperature. ASUS call it Q-fan. Some only control the cpu fan, but mine (P5K) also slows down the case fan | dugimodo (138) | ||
