Currently I have a Corsair H100i installed at the top of the case. The radiator is on top and the fans under that, blowing air towards the top in a push configuration. I'm quite happy about this, except for the noise that the fans are making. It's not incredibly loud, but it's still loud enough to distract. This is why I'm currently looking replace them with Corsair's SP120 Quiet Edition, which has a maximum RPM of 1450, and has rubber around the fans that is missing on the stock fans (SP120L).
Question 1: I know the RPM on the stock fans are higher, and therefore the cooling is probably better since the fans themselves are identical. Still though, I'm currently not overclocking (I'm planning on tinkering in the future though) and undervolted my i5-4670k to a stable 1.010 volts on stock speed, which makes it run 15 degrees cooler in a 'High' stress test with IntelBurnTest than with stock voltage. So I could let this compensate for potential degrees to be added by switching the fans. Will the SP120 Quiet Edition be a good choice?
Question 2: Performance Edition has - I believe - a cap of 2350 rounds per minute but is aside from that completely identical to the Quiet Edition. If I can limit these to 1450 (and thus make them exactly the same as the QE) or lower via the bios while the fans are connected in the fan headers on the motherboard, I would go for those. However, does that still mean It would go to like 600 RPM when the computer is in idle or is the 1500 fixed on that moment? Currently the stock fans are connected to the H100i water-block, not the fan headers. What will be the best way to connect the fans; water-block or fan headers?
