Motherboard and CPU Temperature

Furquim · November 4, 2019

Hey, since a few days ago I started monitoring my hardware's temperatures since I got a new GPU and was testing it to know if I could overclock it or not.

The GPU temperature is more than stable, but to my surprise both my CPU and Motherboard are heating up pretty quickly. It's usually quite hot where I live, so I'm used to getting high temperatures on some of my PC components (mostly CPU and GPU), but this time is different.

While Idle, both my CPU and Motherboard are at around 45~54ºC, with the motherboard almost always having the higher temperature, which never happened before, usually my motherboard was about 35~40ºC max, no matter how hot the CPU was.

Whenever I open a program (and it doesn't matter what I open, from Photoshop to Notepad, the result is usually the same) the motherboard temperature jumps from 45~54ºC to at least 65~70ºC and the CPU follows suit. Depending on the program I opened the temperature goes back to normal after some time, decreases slightly, stays about the same or gets even higher.

The max temperature I got until now on my motherboard was about 92ºC, as for my CPU, it's not far behind at about 90ºC, and it mostly gets this high when I boot Windows or use an Android Emulator, which I guess is to be expected. But this makes me afraid of playing heavier games and end up frying my CPU and/or motherboard again.

I thought that maybe there was something wrong with my sensors, so I touched the motherboard while it was supposedly at 70ºC, and it wasn't hot, however as I got closer to the CPU socket, I noticed it was getting pretty hot, so I checked the motherboard temperature using another software (HWiNFO), and while the "System" temperature was at about 40ºC (which was the norm before), the "CPU (PECI)" temperature was the same as the other software (Speccy) indicated as the motherboard temperature.

So, I'm kind of confused and concerned.

I got to the conclusion that my CPU is whats causing the motherboard to heat up, but at the same time I find it weird that the motherboard temperature is always higher than the CPU.

I don't know if I should worry about those temperatures, I searched multiple times for safe temperatures for my motherboard and CPU but found varying answers.

I want to get a new cooler because I'm worried that this CPU won't survive the summer (it's still spring and we're getting temperatures up to 36ºC here), but I've read that Skylake processors can get bent if you use a cooler other than the stock one, so I'm afraid to do so.

So many parts of my PC broke those past few years that some even call me "Hardware Destroyer" for the bad luck I have with this, and honestly, I can't have anything breaking right now as I wouldn't be able to afford a replacement, so if I seem overly worried, it's because I am.

Anyways, thanks in advance.

bad thermal paste? Also watch the case airflow

I don't think so, I bought this thermal past less than a year ago. And the case airflow is correct, I didn't make change the position of any fan (I have two at the top, one at the back and one at the front).
