Thinkstation P700 without Fan Control / Cooling

2020-05-20, 21:14 PM

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.


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 screenshot from sensors
