Fresh install of OpenBSD/6.7/amd64/install67.fs
on Lenovo 3000 G530 laptop, 2008 manufacture year.
Straight from the start, just after log in:

CPU: 100% idle
load averages: 0.04, 0.06, 0.04

$ sysctl hw.sensors | grep temp
hw.sensors.cpu0.temp0=95.00 degC
hw.sensors.acpitz0.temp0=79.00 degC (zone temperature)

and growed by 1 degC in 3 minutes of inactivity.

Found:
https://www.reddit.com/r/openbsd/comments/gmmh98/has_high_cpuheat_issue_been_fixed_in_67/
which has also this link:
https://old.reddit.com/r/openbsd/comments/e6qf3m/66_t420_heat/
but:
1. no solution there;
2. there temperature average is higher by a few degC,
or rises inadequately under some particular load,
mine - is constantly inadequate under no load.

Also, it takes several seconds for xterm to redraw itself
from top to bottom on my 1280x800 display.
Is it because of NVIDIA graphics?
Has it something to do with high temperature?

I have not tried OpenBSD/6.5 mentioned in the above links - I am
a new-comer.

I have not syspatch'ed - I am afraid of keeping my machine running
at a-little-below-water-boiling temperature. Anyway, both
https://www.openbsd.org/errata67.html
https://www.openbsd.org/plus.html
seem to me to not contain temperature fixes.
