Review on 💦 Enhanced NZXT Kraken X63 280mm - RL-KRX63-01 - AIO RGB CPU Liquid Cooler - Innovative Rotating Infinity Mirror Design - Upgraded Pump - Powered by CAM V4 - RGB Connector - AER P 140mm Radiator Fans (2 Included) by Scott Larson

So I contacted NZXT and told them my pump is making very excessive noise when the pump speed is over 50% (louder than the fans) and also when it is spinning gets on pump. Going down it gets quieter, but when the CPU is busy you either have to deal with too low a pump speed, which raises the coolant temperature significantly, or increase the pump speed and run with a noisy pump (due to lack of coolant). Also a known issue and my concerns were ignored by NZXT so it's coming back. Never buy NZXT for water cooling or cooling in general, they are dead to me.
