Hi,

I have a couple of 120mm case fans in my computer that connect with a molex to the PSU. I would like to have it so that they are still monitored by the motherboard, but then you need to convert them to 3 pin.

I don't think that would be best because they might draw too much power from the board. Is there a way to have them powered by the molex and have a 3 pin going off that to the motherboard that just sends the monitor signal to the bios? So its possible to use something like motherboard monitor?

Any helps appreciated,
Cheers,
Mark

Why would it draw too much power from your motherboard when it is designed for that feature?

I just read on a few forums that some fans use molexs for a reason because the motherboard can't supply enough power to bigger fans? Maybe this isn't true then and I should just get a molex to 3 pin adapter?
