Question I repasted my laptop three times, and the temps are not getting any better

[Nuginugraha]

Hi folks, so I have an Asus TUF FX506 laptop and I figured its been 2 years since I bought it and in the name of longevity I wanted to change the thermal paste. So I bought some Kryonaut from TG, repasted it -- realised I made a mistake and the temps didnt get any better(in fact it got worse a bit). So I bought another one, repasted it properly this time(a dab on the GPU and made a generous line on the CPU) and it had better GPU thermals by about 10° and about the same CPU temp. A month went by and I figured maybe if I do it one more time Id get better CPU temps this time, so I tried it and this time I tried spreading it like butter on toast as evenly as I could -- only to find out that both temps went back up again(Up to 86 on GPU and sometimes 90 on CPU).

Can anyone give me a clue as to why? And how to alleviate this problem? Are there any general Do's and Dont's that I have missed? Any insight would be greatly appreciated, thanks

My guess: That particular laptop seems to have some pretty long cooling tubes, so I'd assume the termal recistance you've noticed the effect from are because of this design.
Most likely, your thermal paste have a very low thermal resistance while the tubes have much higher, so there is no way to noticeable improve the thermal resistance by just optimizing by re-pasting at the gpu/cpu.

Don't spread the paste like butter, too much paste can make temps go up, A pea sized drop in the middle is a good place to start. See if temps drop. If not, look at the coverage of the paste and if not covering enough, after cleaning, use either slightly more, or run a thin short line across the middle of the CPU. Too much can be bad just like too little.

I agree fully with Rokinamerica above. Many people do not understand that too MUCH paste (makes a layer too thick) is just as bad as too little. Check on the web or with paste maker for instructions on exactly how much you need for the particular CPU chip you have - they are NOT all the same! Same for the GPU chip.
