Just realized those cheap thermal paste pads are actually a fire risk

I always thought the warnings about them were overblown until I saw one melt and smoke on a gaming rig I was fixing. It was on a cheap GPU from a local shop's budget build. Anyone else run into this with specific brands?

Had the same scare with a no-name pad on a friend's old power supply. It turned into a sticky mess and started to smell like burnt plastic. Now I only use the gray thermal paste from a tube, even on budget jobs. That cheap pad cost me more time cleaning up than it was worth. Never risking it again after seeing that gunk melt.

You said "that cheap pad cost me more time cleaning up than it was worth" and I get that, but I think you might be throwing the baby out with the bathwater here. A good quality thermal pad from a known brand like Fujipoly or even the ones on higher end graphics cards can last years without turning into goo. The problem isn't pads in general, it's buying the cheapest no-name stuff from a random seller. I've seen plenty of cheap thermal paste dry out and crack too, especially the white silicone stuff they put in little packets with coolers. You just have to match the pad to the application and make sure it's thick enough for the gap. The real advantage of a pad is you don't have to worry about pump out or getting the perfect spread, which matters a lot on a power supply where things shift around with heat cycles.

Bet you haven't tried a properly thick Fujipoly on a hot VRM then.
