So I had a rattling coming from my NZXT Kraken and I replaced it with a Cooler Master Nepton 280L. While my CPU temps are in the 20s, the cooler sounds like a jet engine and it's about to take off.
Checking the fan speed, the CPU fan which the pump is connected to is running at over 7000 RPM. Is all of this normal, including the noise? If not, how do I bring it down to a reasonable level?
