Thinkpads, for a long time have had a fan speed that's possible, but never reached by the firmware's automatic mode. On Linux, this sets the fan to its true maximum:

    # echo disengaged > /proc/acpi/ibm/fan
I use the thinkfan utility to run the fan more aggressively, including 'disengaged' over 70C.

How's your hearing? If any left.

I put in foam-tipped earbuds if I'm doing a big compile or something, but the Ryzen 6850u runs pretty cool most of the time.

Indeed, and for the t480s we could undervolt the CPU to help with thermals but these are not normally accessible to the end user.

So if you are an average user of a Lenovo laptop without technical skills, you probably have a machine that does not meet the advertised performance, and no way to fix it.
