I installed 2 120 mm fans to the case i want to know is there any program that lets me control the fan speed of the 2 fans so when im not needing them as much and want it quite i can slow them down is there ant special program for that.
"Speedfan" is a program that works on some systems: http://www.almico.com/speedfan.php
I could be wrong, but I believe that it works best with fans which have 4 wires and the fans are plugged into the MB. You should also check your BIOS as most MB's these days have temperature controls built into the BIOS.
2) Download and install the Fan Control software for your EXACT motherboard (see motherboard support site). Change from 100% to 50% and listen to see if fan speed changes (noise). A good ramp is 40degC at 50% to 70degC at 100% (will vary).
3) My motherboard can control 3-pin (Voltage) and 4-pin (PWM) fans for Case Fans. Older motherboards may support 3-pin only.
4) Fan must be attached to the proper motherboard FAN connectors just like the CPU fan is.
