Question Why does my CPU have unusually high temperature

[imChill]

Out of the blue my CPU is now reaching just over 100c on idle! - no apps playing in the background. Other times it is on 70c, again with no apps. My PC then, I am guessing because of the high temps, shuts off abruptly. My whole PC is only 10 months old too which makes me a little more worried too. My specs as below. Any ideas/suggestions?

Cooler is the Deepcool LS720.

You should touch both tubes for the AIO and see if one is cold while the other is hot to the touch. If so, then it's possible the pump has failed or there's cavitation/an airlock in the AIO. Speaking of airlocks, how is the AIO mounted in your case? Did you install the AIO and make sure the mount is flush with the CPU's (Integrated Heat Spreader)IHS? Make and model of your case?

What BIOS version are you on for your motherboard?

pump speed?
radiator fan speed?

1- I touched both tubes (temps at 70c currently) and neither are hot. Just mildly cold.
2- I did not install the AIO, it was installed by an engineer. They were quite knowledgeable - I would hope they mounted it properly... Below is a pic of what I can show (not much)
3- Fractal Focus 2 - pic below
4- Pic below of BIOS

Just now, having checked again, temp is now at 40-45c.....?????

radiator fan speed?

Sorry... how would I go about checking this??

As I wrote my 2 last replies my PC shut off again, not sure what the temp was exactly when it shut off, but about 40 seconds before it shut off, it was at 40c!!!!!

Most likely, the aio has failed.
Perhaps debris has clogged the pump or air has intruded into the system through the tubes.

Will this require a whole new AIO??

Yes, if the aio has failed.
But, it usually takes 5 years or so so I would check out other possibilities first.
Perhaps the cooler has come loose.
Perhaps the pump fan is not working.

Have the system checked by the one who installed the aio.

Try looking in bios for fan speed, or use HWInfo.

Your pump speed should be 3100 RPM±10%

Thanks. Ireally don't want to touch anything I don't understand!! I have pasted a pic below, does this help???

Wow, bios shows all fans 16448 RPM, this is strange, something is going to be wrong here. Open the case, see if any cable to the pump or fan is damaged. Check if any connector has fallen out. Let me know if the pump connector is connected to MB "PUMP 1" and the radiator fan connector to "CPU 1".

Edit: and all temps 64°C...
