Just change the PSU and retest :-)
I've done that a few times, as a first step.

Never hurts to change thermal paste. Especially the hobby non-permanent kind.

Some of the paste materials are good enough to be permanently used.
The screened thick materials provided initially on heatsinks
can be quite good.

Hobby pastes vary in endurance. One (which I won't promote by
naming it), reacts with the metal in the CPU and the metal in the
heatsink. That's an example of a bad choice, as some people have
experienced (no warranty support when that damage is detected!).

Some of the others, are well designed pastes, with the right
kind of viscosity, but if you "abuse" the PC, by dropping or
kicking it, that affects the paste integrity (air ingress), and
re-pasting those is a good idea. Like, just handling the heavy
heatsink assembly, applying too much "torque" to it while working
on a PC, can affect it by a few degrees of performance. It's because
the huge heatsinks weigh so much, that this kind of thing happens.
A light heatsink has sufficient normal force to remain in contact.
