fan doesn't work

[joe w]

The fan does not work in either the current version of ubuntu or previous (focal fossa). it was working a few months ago, so this may be new to this kernel, i didn't discover when it stopped working directly :(

symptoms: gets very hot. no fan. eventually blackscreens while the power remains on. `sensors-detect` eventually outputs:
```
Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.
```

`sensors` output is as follows:
```
