[Solved] Laptop temperature peaking at 100°C ?

[CuriousMeow]

Is that normal for a laptop to peak at 100°C (for a few seconds) and for the fans to start spinning like crazy only 1 second after it peaks ?

CPU is i5-1155G7, brand new laptop. Background is that I wanted to test and see the difference between Blender 2.79 and 3.0, I rendered pictures of a very basic scene (just a cube, 2 planes and light), 1080p, low samples. Rendering using the CPU, obviously. The laptop peaked at 100°C with both versions of Blender. On top of that, I feel like there's a high pitched noise for a few seconds too, which defo doesn't come from the fans.

Is this normal ? Is there some setting I missed ??? I don't know much about hardware and stuff, but I feel it's unusual, since my old laptop (which was Intel specs too) didn't behave this way, even when rendering HD pictures or even animation. It didn't peak that hot.

I don't think it's normal, but at least you can make yourself a nice cup of warm tea on it.

Hi,

If your laptop is brand new and seems to have hardware problems (noise, temperature), bring it back to your seller for a warranty repair or replacement.

Regards,

MN

Well, it's brand new from November. As far as I noticed, the issue only occurs when rendering pictures. That's also the only time I heard this high pitch noise.
The temperature will also raise to 85°C when using the video editing mode, when adding a new footage in. But no issue when rendering the final video, though.

I also have a proper computer that was build for rendering, I was already worried when it peaked at 95°C, so the vendor added an additional fan (even if he said 95°C was normal), so that it peaks at under 90°C.


For the sake of adding details (might be useful ???), the laptop had an issue when it was on kernel 5.13, would overheat a bit (around 60°C), when doing simple tasks like installing new software from the software manager. It never happened again after I upgraded to kernel 5.14.


There was also an overheating issue on the W10 part that started after some update, seems to not happen anymore since I updated to the newest version of W10. I do not use W10 often, though. Not willing to try Blender on it. I played Civ6 on it, fans were spinning like crazy, but I get it's normal ? I don't know what temperature though, since the game is full screen, so the temperature thingy is hidden. No issue when playing Civ4 though.

I'll ask the vendor in case of, but I don't think it's defective hardware issue.

I guess that for now I'm just going to not render stuff on it, then.

[CuriousMeow]

I think I found the issue. The threads (for rendering) were "automatically detected" and were set on 8, well that's too much for my laptop. 4 still seems to be too much , the rendering will be at 80°C, peaking at 95°C (but just 15 seconds longer than when set to 8 ). It seems I should go with 2 for the render to be done at 50+ degrees (peaking at 65). 2 It was set on 4 on my old laptop from 2015 (with 4GB of RAM) and I had no such overheating issue. I don't remember the size of the tiles I used to use, though.

Basically, the issue was with the settings. I'm surprised by the value that needs to be lower than with my old laptop, though. I'm not sure if it's adaptive ? Since I really don't know about hardware, I don't know if there's another reason to it ?

Anyway, problem solved.

Your CPU has 4 cores and 8 threads. Threads are not nearly as fast for many types if work as two threads run in parallel in only part of one core. There are other parts of the core where both threads have to wait their turn. 8 processes would generate a lot of heat without gaining much speed when they are nearly identical.

If the threads were 8 different applications, you could get a better result or they might flood the cache and slow everything down.

My old notebook did the high pitch scream for a picture rotate on large images. My new notebook has giant heatpipes that absorb the occasion peak from rotate which means the fans just speed up a little. Your high pitch scream might be a hidden fan or a loose plastic edge somewhere in the airflow. CRTs used to get screams in their high voltage transformers.

Further back, there was the scream of paper tape through a high speed reader. Are you using paper tape?

I'm going to start by stating the obvious : I am literally clueless about all the technical stuff. Also English is not my first language. I'm not sure I fully comprehend what you're saying here.

From the Blender manual : https://docs.blender.org/manual/en/late ... mance.html


I know it's not comparable, but on my computer that is designed for rendering, with Ryzen 5 (don't remember the exact model) as CPU, the auto detected number of threads is 12, with the additional fan, it stays in acceptable heat.
For such a basic scene (just a cube that has a very simple material and 2 planes with no material + light), it will take a few seconds to render and not exceed 55°C.

I really feel that there's something off here (with the laptop). If Blender detects "8" threads, it should be accurate, or at least it should be able to work comfortably with "6" ? Here 8 is obviously hitting hardware limitation. But "4" is also getting too hot, and it took 51 seconds to render.

Also, I'm talking about Blender 2.79, which I'm used to use. I had expected 3.0 to be slightly more resource demanding, but in the end, it took the exact same time to render on both and the laptop behaved the same with both. The real time viewer is more demanding, though ?

Again, I don't understand all the technical stuff, so I'm just comparing with my old laptop (the one with Intel specs too), and basing my judgement on how it usually works on other computers/laptops. It was ok with 4 threads for rendering on my old laptop, and keep in mind I'm talking about normal scenes or even heavy stuff (like fluffy characters, I don't think I could have exceeded 2 in the same scene on my old laptop though, 3 were always taking so long on my old desktop).

The fact that using 4 threads for the lightest scene ever is already too much for the laptop and getting too hot, it just feels very unusual here.

Further back, there was the scream of paper tape through a high speed reader. Are you using paper tape?

I don't think it's a hidden fan, I feel like it was the type of high pitch from electronics, but I can't be 100% sure, though.

All I know (and forgot to add), is that when rendering on a setting of 8 threads and 4 threads as well, the CPU monitoring thingy was at something like 4.50 (maybe even 4.80 ?) GHz. When rendering with 2 threads, it remains at 1.5 or maybe a bit higher. I don't really know what it means, I've read stuff about it, which seemed to mean it's not good ? I don't know.

Anyway, it's not what I got this laptop for, obviously. But it still feels a bit unusual though.

I reckon that to even consider taking the computer back to the vender, unfortunately you would have to test the laptop in Windows and if your temps were unreasonably high whilst rendering simple objects, you might then be able to take the computer back to the vender. I say 'might', as depending on where you are, the vender would have to make various attempts to 'fix' the problem before you would get a refund. The 'fix' might be just to waste time until your year guarantee is up.

If you take it back with the non-default operating system on the computer then the vender will most likely say it simply wasn't designed for that and won't accept it.

Can you try booting into Live Mint and see if you get the same result - it would be an earlier kernel but would be interesting to see if there is a problem with your settings. Also try other different Live distros not Ubuntu based just to compare amongst Live distros.
Also - assume you have already done this - but check in the BIOS to see if there are any settings that may help.
The whine might be from the psu which you sometimes get with desktops/cheap psu.

One other way to test computer / laptop cooling issues, is to run the stress command. It's not installed by default on Linux mint, but easily installed by

Code: Select all

apt install stress

Using this command you can fully load your cpu, e.g for my Ryzen 7 3700x system, 8 cores, 16 threads, I use

Code: Select all

stress -c 16

, and I can watch the system resource meter go up to 100% on all 16 threads, 81C full load, with system fans at ~75 % full speed (set in bios).

Code: Select all

stress -c 16

shows 50% load, and a max temp of ~75C

Another thing you could possibly look at, is your laptop bios may have options for automatic system fan speed control. Perhaps they are set to a "quiet" profile (with lower max fan speeds) rather than for maximum cooling?

You don't say. Even the 7 day no question asked refund/return thingy was void the minute I had them remove W11 to install W10 instead ! From a consumer point of view, it is quite not right...
Apparently, W10 was reinstallable any time or whatever, W11 installs are unique and need to be activated before being deleted ? I know the vendor was unable to just wipe W11 without activating it, there was a Bitlocker warning.

Anyway, I'm not planning on testing much with this laptop, I'll just use it for whatever it's supposed to do, which it does just fine.

As far as I've noticed, everything else seems to be normal.

At worst, if needed, I'll render with 2 threads, which is sure unusual, but whatever.

I'll probably try again with 21 (and kernel 5.15 ?) in the future, see if it behaves differently.

Thank you to everybody who answered.

I genuinely got very angry recently just when installing Win10 on a VM. Win11 had problems as no matter how many resources I gave it on a high spec 2 year old computer, it said it wasn't enough to install Win11. Could have been a problem with VM but was not too much of a problem as was just looking to see how annoying it was anyway - and it was annoying before it even got to the annoying stage.

Good luck with the new computer.

Just a quick FYI kind of thing (even as the thread is 'solved'). But if you have a laptop that feels too hot (under Linux, Windows or MacOS etc) in general use and you are not able/willing to have it exchanged or hardware checked; you can get one of those laptop pad things with fans that blow extra air up into the case of the laptop.

Those can sometimes make a few degrees C difference for high running temps.
