L14 Fan noise after upgrading to Fedora 36

[dean]

I remember in the past there was a way to update the Embedded Controller (EC) so that it’ll modify the fan curves so the fan doesn’t ramp up and down. It worked before but after I updated to Fedora 36 the issue has come back. How can I correct the issue?

https://source.puri.sm/firmware/librem-ec does not seem to be the correct place.

I have a Librem 14 with PureBoot.

there is currently no user control over the fan curves, nor has there been in the past. Fan speed is completely controlled by the EC and a function of CPU temp

He’s talking about the EC.
