So i want to get a PWM case fan, so i dont have to get a fan that will be constantly at like 2000RPM and be screaming loud, but i dont know if my mobo will support it and control the speed depending on load or temperature, etc. I have an MSI FM2-A75MA-E35 board and i want to get a BitFenix Spectre Pro BFF-SPRO-P12025KK-RP 120mm PWM Case Fan. Will the PWM work with my mobo and will the RPM be controlled automatically?
PWM functionality is usually plug-and-play, although sometimes you'll have to make sure that your BIOS is set up properly. (Usually it's called either Smart Fan or Q-Fan. I can't remember if any other brands call their fan-speed-controlling software anything different.) Alternatively, you can download Speedfan; it has the ability to control fan speeds - both 3-pin and 4-pin varieties.
