I would have recommended the Scythe Kaze master 2 KM05 fan controller that I use. But recently the 4th fan header has been giving me issues. After trouble shooting I found out the fan header solder joints broke from the circuit board from being poorly soldered on. Thus explaining why my fan4 wasn't working. =(.
But the main downside is the bad customer service. They have been giving me the ring around for a week, and now have stopped replying via email to me. Just bought it 3 months ago too.
So I'll be looking for a different brand to go with in the future. Let us know what you end up going with.
