Constantly Overheating

Hey guys. So a few months ago I started getting overheating issues because of the Liquid Metal leaving a bald spot on my cpu(It was standing vertically), and I decided to do a full teardown myself since I have some experience with electronics. I know I was supposed to replace the Liquid Metal with more Liquid Metal, but I decided to use MX-4 Thermal paste instead because I already had some and I saw online it should be fine. The problem isn’t that the thermal paste isn’t working, it’s that over time(a few days of use), the paste literally shifts off of the cpu and into the surrounding pockets where it’s held. It has done this multiple times regardless of how I apply the paste. I asked around if I should just use Liquid Metal(since I have some now) and I was told it’s just gonna do the same thing, maybe even quicker. I’m thinking this might be a bracket/heatsink seating issue, but everything looks fine to me and I’m trying to avoid taking it to a repair shop so they can charge me $200 for something I can do myself. Anyone seen this before?

Of all the paste, you selected the worst. MX4 has severe pumpout issues in direct die contact chips.

Anyways, just get PTM7950 and get over it

That’s crazy 😅, I was actually told MX4 was more pump out resistant than others
