I bet you are still depressed that my Zalman Fan Controller is better than that Rheobus..................................I am a jerk aren't I.

You mentioned the buzzing produced by the vantec Nexus, this is not due to low quality parts as you said. The Nexus uses PWM instead of voltage reduction to slow the fans. PWM can cause buzzing of the fans because the voltage is turning on and off quickly (which is how PWM works). The way to correct that is to filter the pulsing via some capacitors before getting to the fans. What Vantec should do is add the filtering.
The sunbeam uses a different method to control
fans in that it uses variable voltage regulators (the parts on the heat sinks), these don't pulse
the voltage so no buzzing happens.

He wasn't referring to the fans buzzing. The actual unit itself was buzzing.
