On a Thinkstation P700 with dual Xeon E5-2620v3 and 144GB DDR4 RAM and one Flex Adaptor with 1x NVMe SSD, lm-sensors report temperatures but not fan speeds other than Nvidia Fan under Fedora 32. There seems that there is no way to control fan speed from Linux [not sure about Windows] On a Thinkstation P700 folder /proc/acpi/ibm/thermal does not exist. /sys/devices/platform/coretemp.*/ exist but those don't show any fans nor fan control whatsoever. Lenovo does say this machine is [certified] for Linux [Ubuntu and CentOS] but neither seems to show fan control as my experience shows. Looking at Lenovo [website] re drivers nothing relevant shows re Linux Fan control: Would be nice to know if fan control is possible under Linux for this platform and which kernel modules need to be loaded. thinkpad_acpi module does not load on Fedora 32 but tried Ubuntu 14/16/18 LT and ArchLinux up to kernel 5.6.13-arch1-1 with similar results Here's the sample of from sensors output coretemp-isa-0001 Adapter: ISA adapter Package id 1: +40.0 C (high = +75.0 C, crit = +85.0 C) Core 0: +34.0 C (high = +75.0 C, crit = +85.0 C) Core 1: +33.0 C (high = +75.0 C, crit = +85.0 C) Core 2: +34.0 C (high = +75.0 C, crit = +85.0 C) Core 3: +33.0 C (high = +75.0 C, crit = +85.0 C) Core 4: +32.0 C (high = +75.0 C, crit = +85.0 C) Core 5: +33.0 C (high = +75.0 C, crit = +85.0 C) nvme-pci-0200 Adapter: PCI adapter Composite: +23.9 C (low = -273.1 C, high = +69.8 C) (crit = +79.8 C) Sensor 1: +24.9 C (low = -273.1 C, high = +65261.8 C) Sensor 2: +23.9 C (low = -273.1 C, high = +65261.8 C) Sensor 5: +32.9 C (low = -273.1 C, high = +65261.8 C) coretemp-isa-0000 Adapter: ISA adapter Package id 0: +38.0 C (high = +75.0 C, crit = +85.0 C) Core 0: +33.0 C (high = +75.0 C, crit = +85.0 C) Core 1: +31.0 C (high = +75.0 C, crit = +85.0 C) Core 2: +30.0 C (high = +75.0 C, crit = +85.0 C) Core 3: +31.0 C (high = +75.0 C, crit = +85.0 C) Core 4: +32.0 C (high = +75.0 C, crit = +85.0 C) Core 5: +31.0 C (high = +75.0 C, crit = +85.0 C)
