Am I the only one who keeps seeing people use thermal paste like it's peanut butter?

I was swapping a CPU cooler for a client last Tuesday in their Dell Optiplex, and when I pulled the old heatsink off, there was a literal puddle of thermal paste squeezed out over the socket pins. The guy before me must've used half a tube. I see this way too often in budget builds people bring me. It's not just wasteful, it can actually mess with conductivity if it's the cheap silver stuff and it gets where it shouldn't. A pea sized drop in the center is all you need, maybe a line for longer chips. Why do people think more is better? Has anyone else had to clean up a thermal paste disaster like this?

and honestly the pea size method has never let me down in like 15 years of building. the trick is to not overthink it, just a dab right in the center and let the pressure from the cooler spread it out. i've had to clean up so many paste disasters where people used way too much and it got all over the socket pins like you said. the silver stuff is conductive so if it bridges anything you're looking at a dead board. i use a little isopropyl alcohol and coffee filters to clean it off, works way better than paper towels. if you're really worried about coverage you can spread it with a plastic card but honestly the pressure does the work for you.

yeah @piper_kim that's the same reason i always double check my gas cap. people overthink things.

That Dell Optiplex with paste over the pins is rough. Did the paste actually cause any boot issues, or was it just a mess to clean up? I always wonder how many of these "pea size" builds I see are actually working fine versus the ones that cooked themselves from too much goop.

Right, the good old thermal paste tsunami. I once put so much Arctic Silver on a cheap Athlon that it oozed down the side and made the CPU look like it was wearing a tiny green sweater. Booted up fine for about a week until the system started thermal throttling in BIOS, so I had to chisel the dang heatsink off with a butter knife. That's the thing with too much paste, sometimes it works fine until it doesn't, but the mess is always a 10 out of 10 on the stress scale.
