I have the same issue here, it started at the moment I moved from the
4.19 kernel to 5.9, and now 5.10. For totally non-obvious reasons fans
start blowing like crazy regularly for a few seconds. When observing
system load, it's just hovering around 0.2 - 0.4, no peaks observed.
This is an Intel NUC with just a Buster system used as mostly inactive
desktop.
FWIW, attached are output of lshw and lspci -v.
