Fan Splitter Question

AltFn · May 1, 2015

If I hook up two fans to a fan splitter like this one:

Will I be able to control the fans speed through a program like speed fan or from BIOS?

Yes, fan speed is based on voltage. Splitting will not reduce voltage, it will however reduce amps a bit. I believe so anyways.

PWM Fans do not use voltage level to control fan speed. The width of the DC pulse is what controls their speed.

With that splitter only one of the fans' speed is being monitored but the same DC pulse is being supplied to both fans.
