Watercooling temp not right

Hey guys,

 

In iCue, the temperature of my H100i Platinum RGB shows the temp of 32 degrees celcius but on coretemp it varies from 49-67 degrees celsius at idol really not doing anything.

 

Should I be worried?

 

Why is the temp different in iCue?

Your idle CPU temp is likely higher than expected because the voltage is up and not relaxed. This seems to be a feature of the Ryzen 3000 series CPUs and there was a lot of flap at launch.

 

As for the coolant, it’s a transport system for heat conducted off the CPU. It’s not a piece of silicon in a water bath. The cpu will always be the warm thing. The coolant temp is a measure of how much heat you have added into cooler vs how much it can dissipate through the radiator. The relationship is +1C coolant temp = +1C CPU temp. Coolant temp changes are relatively small in comparison the range of cpu temperatures. That is a result of the voltage coming from underneath the cpu and there is little you can do about that aside from lowering it.
