Default Question about mob sys fan header
I have 4 Cooler Master R4 120mm green LED fans on the way. Does anyone know if your typical sys fan header can handle that many? Looks like each fan is 1.6 amps.

I would doubt it.

Just to be safe, run them directly off of a 4 pin molex.

A single header handling 4 fans at 1.6amps each? I highly doubt it.

Actually I am going to run them off of a terminal block. But I am looking for an alternative to a bay fan controller.

They're rated at 0.35A ea. Running 2 would probably be OK, but not 4.
