Hi,
I have a noctua 9B CPU cooler, which comes with two fans and a splitter to connect to one CPU header. But reading up, I keep hearing over and over that you should only connect one fan per header, concern about overloading the motherboard etc. I'm new to this building lark, so I'm wary to go against such repeated advice.
But.
First, Noctua (who seem to be a recommended manufacturer) give you a splitter. Why would they do that if it wasn't meant to be used?
Second, the CPU header on my ASUS P8P67 is rated for 12W/1A. The Noctua fans on the CPU cooler are rated at 1.32W each. So a total of 2.64W/0.22A. Even if thats normal power, and they need double on startup, thats only 5.28W/0.44A - still less than half the rated power of the CPU fan header.
I don't see where the concern is, but as I'm new to this I'm wary of going against advice.
