Fans should be under cooling, not under general hardware. Well done me.
In order for this to make some sense I'll describe the fan layout in my case, the akasa omega. The computer is going through rma hell so I'm spending rather a lot of time organising a largely empty case.
Two fans, push pull intake, across a 120mm radiator front bottom of case
One fan, exhaust through radiator, rear of case beside the cpu socker
Two fans, exhaust through radiator, top of case in blowhole fashion
PSU top, back of case.
My board does a charming thing where it provides 3 fan headers, but wires them all together so you have to change all at once through software. This is separate to the cpu fan header, so one of the tidier ways of controlling fan speed is to connect a couple of fans to the cpu header, perhaps with this.
I've been running two scythe fans from the cpu fan header for ages with no ill effects, but since this product exists I feel it might be unwise to run three (or more) from it. I was planning cpu header - y splitter, one end connected directly to the single case exhaust fan, other end via a 30cm extension to a second y splitter which drives the two intake fans in push-pull. This is a fair load to put on the header, scythe 1600rpm fans. It would be bad to burn out the cpu header.
If the above is safe, I'd run the remaining two fans from the motherboard headers, and turn them off in software when the computer is idling. If the above is not safe, I'll connect the front two fans to the cpu header and turn off all the others in software, which will do interesting things to the airflow through the case and may end up with me buying the splitter listed above.
I suppose that's a very long winded way of asking if running three or four fans off my cpu header can kill that part of the board. I'm hoping to avoid using a fan controller.
As an afterthought, how does running fans in series work out? Wiring them so each gets 6V instead of 12
