Pin Fans
why do some computer fans have 3,4 pins.?
Why do some computer fans have 3,4 pins and some only have 2. What is the function of the third and/or 4 wires? I am trying to hook up my fan controller to 2 pin fans but the fan controller requires three pins. Thnx
The extra pins are for speed management. Later motherboards and fans have tech such as "cool n quiet" built in where the fan speed is regulated according to the heat of the CPU.
Fans are cheap - you can fit a new fan to the same heatsink. (if screw holes don't align, glue it on!
