Corsair H75 single rad fan, but both connected to CPU header?

[storyr]

Just did a new build with a Corsair 380t and an H75 for CPU cooling. I have the radiator mounted to the side with just one fan and another next to it (see image here), the temps have been absolutely fine with a single fan on the rad, but I just bought new rad/case fans and am wondering if it's a big deal when installing the fans to have the second side fan connected to the CPU fan header via the included Y cable with the H75.

Once I replace the fans, the setup will be two 120mm in the front as intake, two 120mm on the side as intake (one connected to the H75 rad) and one in the rear as exhaust. Does it really matter how I have that second non-radiator side fan connected? Something tells me it's completely moot but I figured I'd ask.

Maybe not absolutely ideal, but I'm sure there is no problem. The only issue I see is that your way puts that non-radiator fan under a control system based on the CPU temperature rather than on the mobo temperature. Since you plan to have four other fans ventilating the case and I assume they will be connected to mobo SYS_FAN ports for their control, I'm sure this will all work just fine.

Thanks paperdoc. Actually the waterblock from the H75 is supposed to be plugged into the SYS_FAN ports. The 380t has a built on fan controller so the two front and single rear fans would all be connected to that. If it's not ideal for the fourth case fan then I have no problem connecting the second one directly to my PSU.

I see no need to change. Leave that side intake fan as you have it.
