Question Motherboard showing 110°C temperature in BIOS and Hwmonitor

Recently I built a pc with
Asrock a320 hdv r 4 motherboard and
ryzen 3 3200g.

The pc is working flawlessly but whenever I check the bios the temperature of my motherboard is 110°C in idle condition.

Tried restarting the pc after 12 hours even then the temperature is 110°C in BIOS.

Also the result is same in every temperature measuring software including Hwmonitor.

It would be great help if anyone could tell me what can I do to solve this problem.

Try clearing CMOS? In HWiNFO, temps can be monitored from the motherboard sensor and the APU. If the APU shows a reasonable temperature, your motherboard's sensor probe may be damaged, in that case, you should get it RMA'd. Also make sure you are on the latest BIOS which supports the 3200G.

Impossible, Ryzen 3 3200g has a Tmax of 95C and would shut down.
Try running CoreTemp.
I assume that you used the stock Wraith Stealth cooler and the thermal paste that came with it?
I installed CoreTemp as suggested by you.
The reading of cpu#0 is 36°C but there is no reading of motherboard temperature there

Could you please tell me how to clear CMOS?
The APU temp in HWiNFO is 34°C

You'll need to open your case, and remove the CMOS battery for a minute or so. Alternatively, you can try disconnecting your PC from the power and holding the power button for a good minute.
So, the 34°C you saw is representative of what idle temps a CPU should be.
I say your motherboard temperature probe is at fault.

Oh so it's not a problem right?
Will this motherboard temperature sensor fault do any harm to my rest of the components?

It may, if the motherboard has some sort of boost feature, it won't detect the temperature correctly, and may even fry your CPU. OR, it will ask you CPU to throttle if it reads 110C. Either way, not good.

Not likely. Both CPU and iGPU boosting is handled completely by the CPU itself and it uses internal temperature sensors that are scattered all over the CPU die to determine when it's safe to boost and when it needs to throttle back if temperature gets too high.

Motherboard CPU sensors for AM4 are notoriously bad and uninformative for the above reason. Most don't even include them anymore. so something like HWInfo that reports Tdie or Ryzenmaster is best for reading temperature.
