Hey guys, so my friend has a pre-built (yes yes I know, but he didn't know how to build one and I wasn't around to help him, and he was on the clock so he had to), he recently had his motherboard changed out, now with his new motherboard, that thing overheats to around 120c all the time while all the other components are normal. He has case fans, he should have thermal paste n stuff, so could someone give me some reasons it could be overheating like that? His other components aren't like 3090s or anything, just some low tier stuff like 1050s and older AMD CPUs, but I did look at the voltages, they were a bit high 1.3 volts for the CPU, could that be it?

What are the system specs?

We can't help if we have NO info about the system in trouble...

 

CPU?

Motherboard make + model?

PSU make and model?

Graphics card make and model?

etc?

 

It could be a faulty temperature sensor on the motherboard...because 120*C would mean the computer is ON FIRE, or the motherboard is LITERALLY melting.

That for the VRM / power phases are too weak to sustain power for CPU, and its running too hot.

Don't know if this actually translates into computer hardware specifically, but overheating is a common cause of trying to draw to much power.
So, easy thing, even if its not the cause, is to make sure everything has every power plug connected.

Some devices like the motherboard may have multiple power connectors.

My last motherboard had a sensor stuck on 120 degrees. Wether it just started or had been under heavy load. Everting was cool to the touch.

It would help if you told us which prebuilt and the specs of the PC.

I just did in the edit

I don't think it's a faulty sensor, the PC keeps on restarting randomly whenever you so much as close a few tabs too fast, let alone try and launch something.

So why did he change motherboards and why can't he just put the original motherboard back in there,  seems like an easy fix?

 

Or the sensor is faulty...

No clue what happened, he couldn't diagnose it himself so he sent it over to some guy to repair it, said the motherboard was the issue, got it replaced. (I don't think the sensor is faulty, it keeps restarting randomly, I think it's from the real heat)

Seems like the 'repair guy' messed something up then. (definitely didn't test it properly)

Yeah I know he's kinda bad repair guy for sure, took him 2 weeks to find a problem. I think he might have put in a bad motherboard in, shady fellow my friend said.

hold up, if the sensor is the problem, and the PC is fine, could it be restarting just because the sensor "thinks" it should restart
