"Nobody" is a pretty big word to use. There is a real crowd of old f*rts on
this reflector that have been in computers since the beginning, and at some
point would have killed to get internal temps in heat generating components
down (I repeat, down) to the upper 30's, low 40's C. The K3's FP reading is
an INTERNAL reading. If 110 F is a fault temperature, then you could
destroy your K3 by leaving it out in the sun.
My PC is routinely much warmer than the K3, and a lot warmer doing antenna
design number crunching.
I take temperatures very seriously. I just disagree that the reported FP
internal temps are anywhere near a risk. And if the FP temp sensing is in an
SM chip, then it is a contact temperature, that will be warmer than the
inside air, and even less of a risk.
Seems that if I want to buy a K3 used, I'll need to remember to explicitly
request "no non-stock holes". What you propose would be a deal-killer for
me.
