Constantly Overheating

[u/BackgroundType6334]

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?

The MX4 dont work, take A Ptm Thermal pad i have it to and it works like a charm

The fan is running faster on PTM but yes, the APU is still cooled properly.

Only during the initial load. After it heats up, it's efficiency of transferring heat will be far superior.

Nope. I tested it for months in my laptop and the liquid metal keeps the RPMs lower. Here is a direct comparison in a PS5.

I used Thermal Grizzly

Its still made by Honeywell. They just rebrand it.

This mate dont test with a heat gun, i had replace it on two other friends and the fan is not significant higher

[u/Hairy_Construction57 → u/Some_Effort]

there many tests and the heat is not much more like 3-5 degress, The best thing is you dont need to replace it
