How many fans can I connect in series via PWM PST?

The number of fans controllable via PWM sharing technology on a fan connector depends on the output of the motherboard and the current of the respective fans. Motherboard fan connectors typically have an output of 1 to 2 amps. The current rating of our fans can be found on the back of the motor hub and under the technical details.

Example: If a fan has a current strength of 0.2 Ampere and the motherboard fan connector has 1 Ampere, up to 5 fans can be operated in series via PWM Sharing Technology.


Four fans without PST technology can be connected in series via the PST Cable Rev. 2. Their speed is synchronised.

Parallel control of up to ten fans is possible via the Case Fan Hub.
