I encountered the similar issue since 1.9.1-1ubuntu0.4 update. On the
previous version 1.9.1-1build1, if I run a CPU stress test, the fan will
keep going up until full speed (~6000rpm) as the temp rises. On
1.9.1-1ubuntu0.4, the fan sometimes is kept at 3600rpm or remains at
zero. Once CPU reaches over ~90C, it got throttled down to min freq
400MHz. I didn't know the problem was thermald until I reinstalled a
fresh Ubuntu 20.04.2, which worked perfectly, and then basically did a
binary search to find which package update caused the issue. To verify
it's really thermald 1.9.1-1ubuntu0.4, I reinstalled Ubuntu 20.04.2
again, and the fan worked fine as expected, and then updated thermald
alone, and this issue happened. Then I downgraded thermald to the stock
version come with Ubuntu 20.04.2, the issue went away.
