How to set the cpu fan lower temperature?

English Hardware
1

Hi, I’m new in opensuse and wanted to know how to set a low temperature for fan to turn on. I used sensors-detect and sensors to see what’s my cpu temperature, and the cpu is set with a high temperature and crit temperature parameter, but not a low one. I’ve observed that the fan seems not to turn on unless the teperature is high. Is there a way to set a low temperature parameter (like 50º) so the fan will turn on? P.s: sorry for my bad english

Use BIOS settings.

My BIOS doesn’t show any option for that. How then?

Please provide exact info about your hardware.

Are you certain?

  • Your Laptop is quite new – usually the fan speeds can be adjusted from within an “Expert” or “Advanced” section in the UEFI/BIOS …

That’s the problem. My BIOS doesn’t show any option to go expert or advanced mode.

  1. Ask for help from notebook’s producer (MSI?).
  2. Ask for help from notebook’s ODM producer (Foxconn, Compal, Wistron, …).
  3. Dissemble UEFI firmware and investigate it.
  4. Dissemble Windows utilities for this notebook and investigate it.
  5. Investigate MSRs if available.
  6. Use external fan controller. You will need 5V - capable fan controller to use with 5V fans ordinary used in notebooks.

Hi
If no BIOS control, try running pwmconfig as root user to see if fan control possible. Else new hardware, kernel/driver support missing, boot from a live USB Tumbleweed release and see if it works better. Last option, a bug report openSUSE:Submitting bug reports - openSUSE

I found a way to turn on advancedd options in BIOS. It has a hidden key combination (that isn’t shown in the BIOS itself) and I was able to change some things, like thermal configuration (that i switched to auto) and my laptop seems to work better (now it doesn’t overheat and the fans look like they are working) Thanks anyway you all.

What’s your exact laptop model? For Lenovos, I set up thinkfan. I am writing a small module to to control two fans for my Alienware 15. I haven’t really found a “General” fan control software.

12

Yes, Lenovo is a little bit special – for the case of a ASUS PRIME Mainboard with AMD Ryzen 5 GPU, I’m waiting for the next BIOS update … :frowning:

13

Do you know if someone already has made something that can communicate with the fans? I mean lm-sensors can communicate with temperatures and fan speeds, and there has to be a project that handled this fan control one way or another.

Hi
All depends on the hardware, I have mbpfan as well for MacBooks etc… :wink: Then have you tried pwmconfig on your system?
