Thread Starter 
Guys is it safe to use a fan controller for the CPU fan? or should I just let the motherboard do the job?

Some fan controllers provide extensions for the fan anhd have a tach lead so the MB thinks there is a fan connected to it and can monitor the RPM.
The Sunbeam Rheostat fan controllers supply jumpers.
I've used them and they work fine.

When its NOT safe to connect a fan to the MB.
When the fan is a high speed high draw unit... the MB can't handle the load and burns out the circuit!

With a stock CPU HSF, connect to the MB and be done with it.
