Thinkpad_acpi not found

I have a ThinkPad W541 with fresh install of EndevourOS. I’m trying to use thinkpadfan to control my fan, but I do not see thinkpad_acpi anywhere. Doing:

sudo modprobe thinkpad_acpi

returns:

modprobe: ERROR: could not insert ‘thinkpad_acpi’: No such device

Doing:

lsmode | grep think

returns nothing.

I’ve tried forcing it (-f and force_load=1) but same issue. Any help would be appreciated…
