Just get a thick thermal paste. By and large any thermal paste is an improvement over stock. Thicker pastes like arctic mx6 won’t pump out. I like ic diamond 7 karat but that’s out of stock. (all I have left is a random tube of it that I found in storage)

(I do mean any thernal paste is better than stock. I used arctic ceramique 3 once on my i5-7200u laptop and it was still 3C lower than og psste temps)

When I repasted my i5-1135G7 laptop, I dropped 10C after replacing the paste.

All you really need is a tiny blob, one covering the igpu die, other on the cpu.

Mobile CPUs (any any direct-die cooling for that matter) are more prone to pump-out, where the chip and heatsink expand at different rates with temperature changes, and the varying gap between the two creates a pumping action. It’s best to use a thicker paste to avoid it, or even better, a thermal pad. Not that it’s the best in the long run, but I have gotten away with the thinner MX-4 in my laptop for about a year.

If you have maybe $30 to spare, consider buying some PTM 7950 since it’s second only to liquid metal (very hard to get right), and should be good for many years. Be sure to get it from reputable sellers though since there are fakes for PTM 7950.
