[Confirmation]: 2.2.0 works fine on Lenovo Thinkpad P53

[FanDjango]

Just in case you are keeping a list somewhere. Thanks for working on this.

But see PR #75 for a minor fix

I have retrieved the speeds for the different speed bytes:

Speed Fan1 / Fan2

0 0 / 0

1 2030 / 1843

2 2388 / 2088

3 2590 / 2247

4 2938 / 2688

5 3188 / 2990

6 3680 / 3545

80 4243 / 3545

Speed setting "7" is same as "6" on my P53. "80" is the next higher setting, non-BIOS.

The following "Level" settings work quite nicely on my P53, it took a while to get there:

Level=48 0 0 0
Level=49 1 0 0
Level=40 2 0 0
Level=52 3 0 0
Level=54 4 0 0
Level=56 5 0 0
Level=60 6 0 0
Level=64 80 0 0
Level=85 128 0 0

A minimalistic approach also works:

Level=48 0 0 0
Level=52 3 0 0
Level=56 5 0 0
Level=60 6 0 0
Level=64 80 0 0
Level=85 128 0 0

Since I am not using any throttle-control reduction, at high demand the temperature hovers around 65-70 °C with maximum fan RPMs and the GPU and CPU get throttled to keep the system cool.

Either you install throttle-control software to change the throttle behaviour, and/or perhaps change the higher Level settings to a temperature more like 70, 75°C, the build of the P53 limits the envelope of what can be achieved.

That's actually pretty good, on the X1E and P1s that I have I still get throttling with max fan speed, with temps at around 95-100 under load. If you're looking at a throttle reduction software you might be interested in throttlestop
