Question cpu repaste

[hamletrules]

Hi I recently repasted my acer nitro 5 an 515 55 (i7-10750h gtx 1660ti 1*16gb 2933mhz) immediately after the repaste my temps were very good, however only 3 days later they are still reaching 96 as of opposed to 78 when doing the same tasks, I use thermal grizzly hydronaut. If I were to repeat this repasting process would spreading the paste before putting on the heatsinc fix my issue?

usually the pea -method is the best way to do:

gaming laptops can reach such high temperatures easily, might be normal for this one

I know it is normal for laptops to run hot but immediately after the repaste my performance was better as a result of not throttling now I am 15 degrees higher Celsius on avg and running into throttling only a few days after I first did it.

Sounds like pump-out, or paste 'slipped off'. You should check and see what the paste spread on the die looks like.

Tysm for your help is there a way to prevent pump out if I were to repaste?

Some pastes are more susceptible to it than others. It 'was working fine at first, and got worse soon after', is a common scene with that.
The solution is to use pastes with higher viscosity - thick(er) and sticky(ier). These are more resistant to sliding off.
Unfortunately, viscosity is a measurement that is seldom used... that's where groups or communities come in and find out what tends to yield the most success.
Kingpin KPx, Prolimatech PK-3, Gelid GC Extreme, Cooler Master Mastergel Pro V2, Noctua NT-H2, Arctic MX-4... are several samples.

Thermal Grizzly Hydro is tacky, not thin and oily like Noctua NT-H1. Shouldn't be subject to runoff.

The i7-10750h is direct die, no IHS, so absolutely should always be spatula/cc spread, not pea dropped, you need to guarantee that every single square mm of the die surface is covered. Only use the pea drop if really intending to overload the cpu with a giant pea, not the standard pea. That includes the gpu as well if the heatsink/heatpiping is common to both or was also removed.

One thing to look for is fan rpm. At those temps, the fan should basically be running maxed out. If it's not, that's a good cause of higher than expected temps.

With pump out or runout, the heat/pressure of the heat pipes on straight, glassy silicon will force the paste to squash out from between the heat pipes and the silicon surface. This starts happening immediately, as soon as heat is applied to the paste, and gets gradually worse as what's left thins out to the point of leaving gaps in the surface contact area. But doesn't stop there, it'll continue until you start throttling hard and eventually bsod or shutdown.

So if the temps are back to, and staying in the high 90's, and performance is the same as it was before, and the temps are stable and not continually climbing, I'd say the paste isn't likely the issue, more likely the fan or fan curve or power plan or some other factor.

maybe the cooler can be tightend a bit more?

Same fan speed and power plan. So I probably need to repaste and I will do the spread method. Tysm for the help also how much should I put on? A pea and then spread or more or less?

Should be a thin, even layer, like when they say a thin coat of paint. As long as the whole die, all the way to the corners and edges is covered, that's enough. If there's a little bit too much there's no worries it'll squish out to whatever amount is needed. Just make sure to tighten the heatpiping down evenly in steps.

yep I have heard that I would be best off to screw the screws in a diagonal fashion. So as of now I take it that the best way to apply is to evenly spread across the entire cpu with a thin layer, and proceeding this I should do the screws in the order of an x and make sure that adequate and even pressure is applied to each screw. Please let me know if there is something else that I should keep in mind. Thanks for your help.

it felt very tight but idk I tightened it until it was very difficult to use the screwdriver
