What OS you installed on your 424 pro? what is the fan speed at this time? I know you set the auto mode, but what is the speed?

Try to set the fan to high speed. Please also check with your eyes if the fan is working properly.

At full speed the temps gets better, between 81-89 degrees. 1555 RPM according to widget.
The fan sounds and looks like it's working fine.

Normally, the CPU temperature should not be so high. We speculate that one possible reason is that the heat sink of the CPU is not fixed properly, or the thermal paste between the CPU and the heat sink does not work effectively. Would you like to try replacing the thermal paste of the CPU or reinstalling the heat sink of the CPU?

HAs anyone considered the impact of Nvme drives running on the system? These have been known to run hot and might generate a general high internal temp that would inhibit cpu cooling. Noone has mentioned whether nvme are in use, but I suppose at least 1 user is, since stated no HDD inserted. Just a thought.

Since there are vents for ventilation and heat dissipation on the sides of the chassis of this model, according to our test and verification, even without the installation of heat sinks, the m.2 SSD itself would not be prone to high temperature overheating, even under full load. The likelihood of your inference is not high.

I've remove the heat sink. Thermal paste and heat sink installed as they should be. Pressure was good and even, thermal paste covers the CPU crystal by a good margin, nothing abnormal.
I've changed default thermal interface and put some mx4 found at home. So, I don't see any big changes with the same type of loads (Win10 download some stuff in VirtualBox) on CPU.
It is noticeable that the auto mode of the fan does not change speed depending on the temperature, so it kinda broken in TOS6.
I also noticed that my F4-424 Pro has an N305 CPU instead of the N300 mentioned in some reviews, according to Intel datasheet N305 has higher TDP.

I have 2 nvme installed (evo 970 & evo 980) and 2 hdd's (Exos X22)

The newly released TOS 6 version in the future will add the linkage function between fan speed and CPU temperature.

I hope it will be released soon.
But what with temp of my unit, is it normal or i should ask for replacement?
