I don't have any special settings in my BIOS, but I was able to control it in windows via an HP software. Yes, I did re-run sensors-detect quite a few times after adding the line. Thanks for the reply, here are my answers: This may also change the CPU frequency governor. I don't have a modern laptop, but AIUI, on recent and well-supported machines power-profiles-daemon can tell the firmware to switch between various power/cooling modes. I believe there's a setting somewhere in gnome-control-center, if you're on Gnome. Try using power-profiles-daemon to set the power profile to "performance". Because laptop chips have lower max clocks and power limits, the currents are lower and the worst hot spots don't get as hot, so it's alright to run them a little hotter than desktop chips. 80☌ is perfectly safe, and most Intel CPUs will not thermally throttle until 100☌. The person or persons who designed your laptop's cooling system are probably not idiots. It's possible that the laptop is designed so that some embedded controller does everything. It is not guaranteed that you can control the fan speed from the OS. PS: Here are the output images of s-tui (stress application & monitoring tool) & sensors images on this linkĭid you re-run sensors-detect after adding acpi_enforce_resources=lax to your kernel command line? Can anyone point out what I did wrong or what should I do? Thanks! ![]() I am not sure why the pwmconfig isn't working. Thus, I wanted to control my fan speed as they are very silent even when cpu temp is 80+. (and yes, they did displayed the rpm when running sensors). I wanted to control my fan speed as I found out that even during heavy stress test (CPU based, in fedora), they didn't ramped up to cool the cpu and they just had the speed of around 2500-2900 rpm, which was still very silent, to the point that you would have to come very close to the fans to hear it. My laptop fans usually stay inactive (even in windows) and only becomes active when doing heavy tasks. The pwmconfig gave the same response, no sensor found! I searched the internet and found this method and did this to grub file GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_enforce_resources=lax"Īnd updated the grub and restarted. I then ran pwmconfig and got this response /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed Then I ran sensors and got the below response * Chip `Intel digital thermal sensor' (confidence: 9)ĭo you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): YES I installed lm_sensors and ran sudo sensors-detect and gave Yes to everything for scan and this was the output Now follows a summary of the probes I have just done. ![]() So, I recently installed Fedora on my HP Envy 14 (2021) and wanted to get fan controls on it.
