Case fans connected to Mobo, or PSU? Tags: Power Supplies Cooler Master Cases Components Last response: May 15, 2010 3:20 PM in Components Share BlackSushi222 May 15, 2010 3:01:26 PM Hi, just a quick question. My case (Cooler Master Sileo 500) included 2 case fans. I connected the back fan to the mobo, and the front to a 4 pin molex from the PSU. The question is, does it matter where you connect them? Will it affect performance of the mobo or fan speed? Thx!

Depending on the case fan, it may make the fan adjust speeds up or down through the MOBO sensors, again nothing to be worried about. BlackSushi222 May 15, 2010 3:20:20 PM Thx a bunch!
