Warning: That cheap thermal paste I used caused a 5 degree temp spike
I was working on a customer's gaming rig last week in Austin, a Ryzen system that was running fine but they wanted me to reseat the cooler after a move. I was out of my usual Arctic MX-4, so I grabbed a $3 tube of some no-name paste I'd picked up at a flea market months ago. Applied it like normal, booted up, and the CPU temps jumped 5 degrees under load compared to the old paste. I ended up stripping it all off and driving to Micro Center for a proper tube, which fixed the issue. Lesson learned: don't skimp on something that costs a few bucks when it can mess with heat transfer. Has anyone else gotten burned by off-brand thermal compounds?
