Ok I have my Sonata 120mm Case fan at 5volts, its pretty quiet, but could be quiter still. It moves a ton of air as is at 5volts so I can drop some off for less noise.

I already have it at 5volts with a Zalman controller.

I have an unused FanMate from my Zalman 7000alcu
If I were to insert a fan mate between the controller and the Fan, and set it to mid point, would this increase my voltage range downwards?
Safe?

Well I went head and tried it and it works a treat!!!

I set the Zalman fan controller to minimum, 5 volts, then plugged in the Fanmate in beteween the fan and the controller. Set it to minimum, the fan stalled. Then nudged it up a bit until the fan started, and then wound a tiny bit more on.

This puts the 120mm fan at around 700-800rpm. Damn it's so quiet but way lower in airflow. The voltage must be around 3 volts? Well the fan runs fine, with no stuttering. Its not the factory 120mm case fan though, but a 120mm Evercool aluminum medium speed fan.

I set it at 900Rpm, and now my system is damn near silent from where I sit :)

Temps seem about the same for now at idle
Wonder if the factory 120mm case fan can start at voltages this low?
