Stock CPU overheating to 90 in 4 minutes

Please describe your CPU cooler in more detail than, "... the CPU cooler and the radiator...".

The CPU temperature, or CPUTIN, is coming from the CPU itself, not the mother board. If the CPU temperature sensor is faulty, then that is a CPU defect.

The Package temperature shown might be the CPU socket temperature sensor.

HWMonitor is showing the CPUTIN temperature as a minimum of 72C, and a maximum of 80C.

The Package temperature shows a minimum of 73C, and a maximum of 85C. Given these are different sensors, they are quite close and in agreement. That tends to indicate no defect in either sensor.

We can see core usage maximums in the high 80% - low 90%. Have you heard of the Windows 10 issue of 100% CPU loads for no apparent reason, that affects some system? I thought that might be an Intel only thing, but perhaps not.

Your VCore values are all under 1.0V, the minimum to maximum being 0.888V - 0.904V. Very little difference between the two, and a low VCore for 80C+ CPU temperatures.

Your core clock speeds of a maximum of 1419MHz, is either throttled or the CPU power saving options enabled core speed. No where near the 3.5GHz base clock or 4.1GHz Turbo clock speed. It looks like a throttled speed IMO.

So I would say something wrong with the CPU coolers mounting, or its function, or both.

CPU temperature can increase from 30C to 100C in a few seconds given a stress test load, high VCore, or poor CPU cooler function. Notice I said or poor CPU cooler function, which means the CPU temperature can climb to 90C - 100C in a few seconds with good CPU cooler function and a stress test load. Four minutes is not needed for the CPU temperature to reach 80C - 100C, that would indicate fantastic CPU cooling ability.

Not being able to feel any heat in the CPU cooler system could indicate incorrect mounting, or the pump not working, since you mentioned a pump.

What I notice right away concerning overheating is that the RPM of your CPUFAN stays constant.

If that's the MINIMUM RPM of the fan, then I'd say there's your problem.

It's not raising RPMs during boot as expected. Whether that steady RPM reading is due to a fan setting in BIOS, a fan setting in F-Stream, a defective fan, or maybe too a defective fan header on the motherboard, I can't say from here.

If it's a 3-pin fan move it to the other CPUFAN header and report back how it responds. But it shouldn't be staying steady as it shows.

A small correction: The CPUTIN temperature is listed under the motherboard, so it is based on data provided by a sensor on the motherboard. In other words, it is the temperature given by the sensor in the socket. The package temperature is from the CPU.

Hi Everyone,

Sorry for not responding earlier. At this point my guess is as good as yours. Have you tried connecting regular fans to those same fan connectors to see whether they also stop spinning?
