Yes, it was bad (cracked) capacitors.  I was thinking that the GPU
temp was correlated to the capacitors cracking (and correlated to the
heat inside the case).

How would I go about checking the case temp?  This is what I get with
sensors. Based on some of the readings, I don't think the
it8712-isa-0290 is accurate.
