This is controlled by the EC. I agree the fan speed is smoothed out over way too long a period; it seemed sluggish to me way back in December too: Any reason NOT to buy the most-souped-up 13 AMD? Upside of lower tiers? - #15 by pierce
I find that it still takes 15-ish seconds to start spinning up, and over 30 seconds to reach the appropriate level for high load. As you say, maybe a minute to reach max, but perhaps reasonable after 30-40 seconds. Seems similar to 3.03.
You can use ectool
to check fan speed, force a specific fan %, or switch back to auto fan speed. Check towards the end of this thread for how to get ectool: Exploring the Embedded Controller
Once you’ve got a working ectool:
$ sudo ectool pwmgetfanrpm all
Fan 0 RPM: 3916
$ sudo ectool fanduty 50
Fan duty cycle set for all fans.
$ sudo ectool autofanctrl 0
Automatic fan control is now on for fan 0
So anyway … yeah, would be nice if the fan responded faster, and if it was easier to adjust the auto-fan-ctrl. There may be a way, but I suspect you can’t make it respond faster: [RESPONDED] Changing the fan temperture points with ectool
