Looking a a scythe katana 2, case shoudl have good airflow, anyone see a problem with this one? I tkae it its HUGE? Its says its three pin fan, i though CPU fans were all 4 pin? Would i need a convertor?

You can get 4 pin molex and 4 pin PWM fans.
The 4 pin PWM fans like the default Intel stock cooler basicaly have the same connector as the 3 pin fans except obviously an extra pin, this plugs into the normaly labeled CPU fan header on the motherboard which is 4 pin but also can take a 3 pin if required.

The 3 pin will connect straight onto your motherboards fan header or to your power supply through an adapter.

Hope the above makes sense

I think so.. So i could plug the 3 pin into the CPU fan header on the mobo and it would work, but the Mobo would not adjust speed, so it would alwyas run 100%? Or i can use a wire from the PSU to run the fan directly... If nothing is plugged into the cpu fan header it wont cause problems im guessing..

It will control but not by the PWM method, when you boot into thr BIOS there is an option usualy to say how you want to control.
