So i have a Scythe kaze fan controller, However the mosfets on the back reach temps of above 100c !!? Is this normal/Within range?

i am not sure if its normal for fan controllers to be hot or just a faulty unit?
 
They should not reach that temperature, even when the controller is under heavy load (i.e lots of fans spinning at max rev/min)

Is your fan controller near any other hardware which dissipates mass amounts of heat? I'm assuming your case has good cooling, thus the need for a fan controller.

How did you find this temperature?
If your positive this is the correct temperature I would RMA the fan controller, probably a faulty circuit.

Ok thanks, Ironically i found this temperature by putting one of the fan controllers temp probes on it :p, however it maxes out at 100c
 
They do run hot and are designed to do so. If you are worried you could add a heatsink to each mosfet and then you should see things improve greatly as heat can be transferred to the surrounding air with more efficiency. I wouldn't worry too much though, unless you go over the max current allowed per channel.

The mosfets work by dissipating all unwanted energy as heat plus they aren't particularly efficient so even a fan running at near 12v still creates warmth. So running a high current fan slowly would create the most heat, or at least they would if I understand how voltage regulator mosfets work.
