One - noisy fan running most of the time

Avatar
Ian

Hello. I've been super happy with my Slimbook One for a few years now (Ryzen 7 4800H). My only issue is the fan noise. Currently, I have a dual boot with Windows 11 and Ubuntu 22.04. The fan is noticeably louder and more frequently on when in Windows, but still pretty noisy on linux. I don't want to start messing around with the fan control settings in BIOS without some guidance.

Running Windows with a web browser for this forum, File Explorer, KeepassXC password manager and the settings app open, the fan is running quite a bit, and running faster/louder than I would have thought necessary for such light CPU load (CoreTemp shows average of around 5%) . The core temp is fluctuating between 33 and 49, particularly when I start typing, when it remains in the 40's. I'm in the UK so pretty low ambient temperature. 

I guess my first question is, are these temperatures normal for this light usage? And second, does the fan need to kick in for this temperature range? Therefore, can I safely adjust the temperature at which the fan starts running? 

Thanks for any time and help.

Ian

Dear Ian,

thank you for reaching out,

did you change the thermal paste or did any maintenance to the computer?

If not , please find below an article with several videos on how to open it:

https://slimbook.com/en/blog/guides-2/post/one-amd-videotutorials-331

Please check if the cooler any dust that is blocking the finstack on the heatshink and remove it with and air duster,

when you turn on the computer don't put the lid back wait and check if the fan is spinning correctly , if you see something weird like bearing not being properly in place put it back in place by applying a bit pressure.

When you use Windows 11 you may now that with all the bloatware that comes with copilot and telemetry services there is a lot of background services consuming ressources even doing minimal tasks.

Please let us know if there are any improvements.

My best regards.

Just in case, please also do check that the screws on the motherboard in case there is  some rattling noises:

Hi Ousama.

Thanks for your advice. I've opened it up, got rid of the dust, and cleaned and put new thermal paste between the CPU and the heatsink. I've also put a very small folded tissue directly under each rubber foot (outside) to lift it a little higher but mainly to absorb any vibrations - I did notice the fan was quieter when I had the pc in my hands compared to when it was down on the desk. I'm not too sure if the new paste has made a difference, but it looked like it needed doing, and especially the dust.

I'm not able to get temperature readings of the CPU cores on Linux. When I run sesnsors-detect, lm-sensors gives me this output:

Driver `to-be-written':
  * ISA bus, address 0xa30
    Chip `ITE IT8613E Super IO Sensors' (confidence: 9)
Note: there is no driver for ITE IT8613E Super IO Sensors yet.
Check https://hwmon.wiki.kernel.org/device_support_status for updates.
From what I read it seems the relevant driver is not in the kernel, which surprised me, so maybe I've got that wrong.

I know it depends on usage, but could you say an approximate cpu temperature range that I should be seeing for 'light' usage.

Thanks again.

Ian

PS: Thanks for the Windows tip. I had already run a debloater, but have done it again using winutil (Chris Titus Tech).

There is no in-kernel driver for the ITE IT8613E yet.

That’s why sensors can’t show actual temperatures.

Try running:

sensors | grep -i 'core\|temp'

Each of those returns temps in millidegrees Celsius. If they’re around 40000 to 50000, that means ~40–50°C, which is normal.
