Is there a way to control the fan speed? I bought a replacement fan with the same specs 5v 0.2a but is rated at a higher speed so therefore much louder than the original fan. Can I control the fan speed through the software or do I need to control it through hardware? Thanks.
Im still wondering this myself. Does anybody know?
Stock Fans are dumb and are regulated via voltage. @ 5v they reach about 10k RPM. If your replacement fan has a third yellow wire, you can control it via PWM signal, but that would require and external PWM fan controller.
