Paste shouldn't be an issue that fast. Shape of the cpu heatspreader likely isn't relevant either.
My money's on the mounting for the heatsink loosening over time / with movement of the whole machine. Don't know what that one looks like so can't say anything definitively. To test, try retightening the mounting (don't crank hard, just get it firm).
Prob pump out effect. Could be premature drying as well but id doubt it. Lets also remember that mx4 is close to 20 years old paste so if it was one of the first or middle batches or anything close, it would have been the normal behavior. Check the registered dates on the syringe, usually it's yearly registered so more than likely if it says 2014 it's 9 years old.
When you take it out does it look exatly how you applied? If so, it's pump out effect as I said before. Happens alot depending on the mount and if it was correctly pressed. Did you use the X tighening method?
Last time I repasted it with much greater amount and spreaded with spatula.
Not X but it has the numerical order from 1 to 8.
And yeah, it is a pump effect...
Next time, try thigteneing the screws on an X Factor, like one turn on screw1, one turn in screw 3, one turn on screw 2, one in screw 4, and looping until it's properly fixed. Gaps can not only dry the paste but also oxidate it, lowering quite alot it's thermas propierties.
Id say it's twice what I use on my clients. Too much Caan also hurt performance. And id recomend not spreading as well, but on bare dies like notebook CPUs the dif is marginal
For me it looks like you are applying a bit too much maybe? Also there is part of the chip with less coverage that might be causing the hotspot.
But yeah, can’t really judge Cus I’m doing pads only now.
Emm I have this problem with the factory thermal pads. They were ruined by the local service, then I changed it by myself.
Only used 1.5 and 1.0 mm thickness. With digital caliper I mesured the thicker was 1.3 mm and the thinner 0.9 mm.
Here you can see what I have done.

Seconding the Honeywell PTM 7950, repasted from liquid metal to it and similar performance. In theory, should have less pump/leak out but verdict out on that, still should be last very long time, it likes higher temps.
I used mx4 on my work laptops fine. On gaming ones, it does dry out with higher temps sustained for long periods.
In the end I decided to try the Honeywell PTM 7950 and I can say after 2 months the temperatures do not exceed 80+ C.
The pump out effect is obvious with the thermal paste (Arctix MX4).
So, big recommendations for PTM pads.

Sending you some pic in DM.

It is 2021 reg date. "Best Before Jan 2030." The paste is fresh not dried.

Okey, I will try that now. Just cleaned it and ready to apply.
Go for it, have fun!
What do you think about this amount? Spreaded with spatula. https://imgur.com/a/FCRLibu

Don’t you think MX4 is just not good enough for those temps and it degrades?
It is better than factory thermal paste... You can see here there is like 25-28C difference between cores: https://imgur.com/a/igJvHPX
Yeah but difference between cores doesn’t mean bad paste, it means bad application.
Used different patterns, always the same. With too much paste it will instant show on all cores high temps with thermal throttling.
How does it look when you open it up? Any visible problematic spots? That’s why I moved to Honeywell PTM. Easy application and so good.
Looks like this.... https://imgur.com/a/3gzQXsH So is this too little? The paste is fresh.

How your PC/laptop peform with that honeywell ?
I got +40% performance from stock. My factory application was trash. Uber trash.
Where did you buy thoose, aliexpress or ebay?
I had a similar issue but with a GPU , the cause of my troubles was that the thermal pads were too thick .Hope this helps .
