It gives me a gain of approximately -7° C the benefit is even greater at full CPU load. On Mint, after only repasting of CPU/GPU with Phobya NanoGreace Extreme, I obtain 42° C ** on "CPU Temperature Indicator" software monitoring. My Dell 9570 (Intel i7-8750H) runing on Linux Mint 19.1 and Windows 10. You can also disable i8kmon to try ik8fan to manually control your fans (not recommended as you might turn off your fans and they will never be started putting your CPU and GPU danger!). Simply i8kmon service will be started and will control your fans. Then follow this guide to install i8kutils: sudo apt install i8kutilsĮcho "options i8k force=1" > /etc/modprobe.d/i8k.confĬonfigure i8kutils: sudo -H gedit /etc/nfįinally, disable Dell BIOS Fan Control with this program by TomFreudenberg to let i8kutils take over. Reboot, and the fans should be visible with: sensors To see the fans with lm_sensorsĮcho "options dell-smm-hwmon restricted=0 force=1" > /etc/modprobe.d/nf Any suggestions to gain control over them? I guess that Ubuntu is unable to see the fans and is thus unable to take control over them. proc/cmdline = BOOT_IMAGE=/boot/vmlinuz-4.19.2-041902-generic root=UUID=5394fef0-92d3-4753-a6a1-fd7b5c4f9cea ro quiet splash quiet acpi_rev_override=1 acpi_osi=Linux scsi_mod.use_blk_mq=1 nouveau.modeset=0 npm=0 mem_sleep_default=deep vt.handoff=1 Installed smbios-utils and set it to different modes (balanced, cool-bottom, quiet, performance) Undervolt by -140 mV on core and CPU, and -40 mV on iGPU (using this link) Set the graphics card to Intel for power-saving Installed and activated thermald, tlp, powertop and intel-microcode. Lm_sensors: cannot find the fans even after "sudo sensors-detect" On Windows, the fans are completely off at idle or light work. I think the fans are activated somewhere within this range, then cool the CPU and thus get the signal again to stop the fans, etc. The CPU temp is between 39 - 42 degrees celsius. Everything works properly, however the fans are continuously going on and off. I'm running dualboot Windows 10 and Ubuntu 18.04 (using the respin from this link).
