Adjust MasterLiquid 120 pump speed

Recommended Posts

Is it possible and safe to adjust the pump speed of the MasterLiquid 120, 120 Lite and 120 Pro AIOs?


I've read conflicting reports that you can:

1) Set a custom PWM "fan curve" to reduce the speed of the pump, and therefore the noise.

2) Reduce the voltage of the pump in the BIOS to reduce speed and noise

3) Should only run AIO pumps at a full 12V, and that giving it any less could damage the pump.


Is it possible to safely down the pump a little bit on the MasterLiquid series of AIOs?

Hi Casey888.


It's not recommended to do this since the pump has been designed to run at 100% all the time ;)


Please Note: Lowering the pump RPM can decrease the performance of the cooler along with increasing CPU temperatures.
