Fan header question

post #1 of 8
Thread Starter 
hey guys, i have purchased an asrock p67 extreme4 mobo and a silverstone ft02 case. from the diagram and information in the booklet, the mobo has 3 chassis fan headers. however, my silverstone has 4 fans. i think i need to plug the 4th directly into the power supply, is this correct? is there any special equipment i need to do that?

also, there are other fan headers too, such as 2x cpu fan headers and a power fan header. i know ill need 1 cpu fan header for my cpu cooler, but is it possible to plug the 4th fan into the 2nd one, or the power fan header? I dont know what the power fan header is for.

for reference, my power supply is an xfx 850w black edition.

thanks guys

there should be 3 fan headers and/or additional/optional fan headers.

if you have many fans, it will worthwhile investing in a fan controller.

You can use any of the fan headers, you can also get a Y-cable and connect 2 fans to each header. You just have to be careful if using high speed fans that pull more amps than the headers are rated for. Shouldn't be a problem with ordinary case fans. Typically the CPU headers will be rated for more amps than the chassis and power headers. The CPU fan header on my P6X58D is rated for 2A(24W)

to plug the forth fan into the psu u need a connector, search on newegg, molex to 4pin or if it is 3 pin then search for that. this connector/adapter conencts the fan plug to the other of the psu.

so plugging them into the power fan/spare cpu fan slot are okay? the fan is the 120mm exhaust fan on the top of the unit

is this method better than plugging them into a spare cpu/power fan slot, or it doesnt really matter?

It might be better.

You can use a Y connector with no problem if your fans pull about 1 Amp combined (~ 0.5 Amp per fan). This info should be on the fan, if they have a label on the center hub.
