Im cooling my CPU with the NZXT Kraken X53 and running between 48-60 degrees Celsius. It's performing similar and in some cases worse than the stock Wraith cooler. The liquid in the loop stays anywhere between 28-31 degrees Celsius. I have the pump sitting at around 1300rpm, any higher and it makes a bad whining noise. The CPU isn't overclocked and regularly sits at 4.16-4.2gHz and 1.4V. Any suggestions to improve my temps?
