Filtered or un-filtered? what frequency?

The unit we used for testing was working on an unfiltered circuit. The frequency actually varied depending on the demand required to cool the CPU to the target temp.

The controller did not rely on the motherboard to set or take target temperature the test unit is equipped with it own sensor. The motherboard sensor was only used to plot temperature vs CPU load.
