You will most often see the H115i Temp and your motherboard temp sensor hang together and this is a decent approximation of the case temperature. The heat still has to pass through the CPU from pin side where it is created to exit through the lid, TIM, and then cold plate on the pump.Īt idle with minimal voltage, your coolant temp cannot be lower than the general case temperature. That does not mean the system is not working and on any modern CPU, the limitation in performance will be voltage. It's temperature will rise with continued CPU activity, but it is slow to change in a healthy system and you are unlikely to see a change of more than +6C or so. The coolant serves as the waste dump and transport for heat coming off the CPU. I'd suspect all numbers you've seen so far. 43C on the other hand is bit too high idle temp unless ambient is really high (25C or more in the room where the computer is). It is not a value most other monitoring tools can pick up and it is certainly not the same as CPU temp or any of the core temps you see in Speecy or HWMonitor. 25C is too little and unrealistic unless the ambient temp is really low. That is the standard control variable for your fans. However, the only temperature shown in your iCUE screen shot is the coolant temperature to the right of the pump image (Temp 1 which is normally referred to as H115i PRO TEMP). Still not 100% sure which values you are referring to.
