for some time now, my kraken aio x53 has been acting up. the liquid temperature sometimes rises to over 200 degrees and clocks my fans at 100%. the problem here is that the liquid temperature is definitely not that high, as the hose doesn't feel that warm. i don't know what else to do apart from reinstalling the instant software and reattaching the pump.
Hey!
I had the exact same issue as you. What worked for me was turning off the PC, turning off the power supply switch (if it has one), then unplugging the power supply cable for 10 seconds. Don't know why, but it worked for me.
