Hardware Question - A7N8X oddity

[Dave A. Marquis]

Well I have... an msi board now that has done the same thing since it
was brandy new.... maybe it is a design flaw or some thing. It generally
happens once in awhile after I reboot the box..... So I just don't do
that very often.

Cleaned (removed fan and cleaned out dust etc. in heat sink and on fan)

AC3 is what I used when I originally built it - I think 2.5 years ago
(maybe 3.5 years ago - winter before RH9)

Anyway - thanks for the tips!
