Laptop Heating issue

[alessioAlexxio]

Hello,

my laptop with the following CPU: 

 Intel® Core™ i7-1355U 12 MB L3 cache, 10 cores, 12 threads (with iRis Xe graphics).

has temperature problems.

When I'm doing 3D work or having multiple programs opened, the PC doesn't show any visible lag but it starts to heat up very rapidly, like from 50 ° to 85  and gets very hot in the back°.  I Ran the HP diagnosis test and the results showed no problems. I worry that with time passing my CPU will degrade and lose power or even break.

 I tried to do Stress tests and it reaches a temperature of 90 ° and sometimes peaks at 100 ° and I think this is not very optimal. my question is why is the mainboard, not entering safe mode for the processor is that normal?

I have attached an image for reference.

I appreciate your help.

Hi,

It is quite normal for the CPU to reach and stay at 80 degrees under heavy loads and will not harm the CPU.

The Tjunction (max temp) for the CPU is 100 degrees and before reaching this temp the CPU will throttle. There are mechanisms to protect against overheating.

Hope it helps,

Hi!

alessioAlexxio, as mentioned by iomare EXPERT Level 15 there is no risk where the CPU is concerned, since it has its own "internal" safeguard mechanisms. The picture you posted, if I understand correctly is from a stress test, shows normal peak temps for a burn-in test. Temperatures between 50-85 Celsius for CPU/GPU intensive work is totally fine......... Processors don't really degrade when working within their specs, this is an issue mostly when it comes to overclocking. The motherboard and the rest of the nearby components however are not getting any longevity points.

Other than repasting your CPU with a better quality thermal compound, there are also many ways to slightly limit your CPU's performance. You can do this from BIOS setup, WIndows or even use third party tools. However, since you're doing demanding work on this laptop, you will certainly notice the throttling. Unfortunately, running a modern multi-core processor at its full capacity and having a cool system at the same time is next to impossible......
