Aluminium asus laptop - Application and thermal paste for it.

F4BIOD3V · Jul 31, 2018

Hello there.

I have this laptop from about 3-4 years and I have never replaced its thermal compound.
Now that is summer, my inner room's temperature is about 30-32°C and my laptop is running quite hot. While I'm writing here it's stuck at 50°C but in about 20/30 minutes of a soft game session it reaches 95-96°C (I guess I will see some throttling at 105-110°C).
Also it reaches 70-75°C for an average use.
This laptop has always been running hot and it's very watt hungry.. still I want to try to clean its fan and replacing its thermal compound.
Searching on the web, I'm not able to choose from the thermal grizzly Kryonaut or GC-Extreme.
I wouldlike to take the one that gives me the best performance and that last longer.. so which one you would suggest me?
Moreover, is 1g of these two enough for just a cpu and gpu application?

My target is just to get a max degree of 80-85. Surely 95-96°C is too hot, for me and for my laptop's sake.

Just for giving more info about my laptop:
It's a N76V. So it has an i7 3630qm and a GT 650M.

I would just get some noctua NT-H1 for an old laptop, you don't need kryonaut lol. NT-H1 will last longer than that laptop will. If you are really set on those two for whatever reason I would recommend kryonaut. 1g should at least be enough for the gpu and cpu.

Since this laptop has always been hot I guess I need an overkill way to cool it.
Its airflow is quite bad and I guess that using the noctua thermal paste could not increase its cooling performances..
At least using a kryonaut I can see if using a top thermal paste could avoid my laptop to reach 95-96°C.. Is the logic behind correct?

Not really, I would guess kryonaut may do 1-5 degrees better than NT-H1 or other decent pastes such as arctic MX-4 or AS5. If the paste that is currently on there is old and dried up than any decent paste is going to reduce temps. You seem to think there is a night and day difference between say kryonaut and something like NT-H1, that is just not the case the difference will be very small likely not even noticeable.

If you feel more comfortable getting kryonaut then go for it. The difference in price is very little. But the difference in cooling performance is very little as well.

You might be able to undervolt the 3630qm a tiny bit using Intel Extreme Tuning Utility; that could help bring CPU temps down (you'll have to play with the voltage offset to find a sweet spot between stability and temperature).

Beyond that, a good (rep)paste should help, especially if the laptop is still using the factory compound. Noctua NT-H1 is good stuff. IC Diamond, GC Gelid Extreme, and Kryonaut might cool things by another couple of degrees Celsius, but will cost more $.

I'm looking their price in order to choose one from the ones you all suggested me.

NT-H1 sells here for €8 (1.4ml)
Thermal Grizzly Kryonaut sells here for €9 (1g)
GC Extreme €7 (1g)

They are all aligned according by their price.
Just one more question: is there any sort of "fast degradation" over these 3?
What I mean is, is there a possibility that one last less than others due to its technical composition?

F4BIOD3V :

People claim the GC Extreme degrades a bit quicker due to its low viscosity. I haven't come across similar feedback for the Kryonaut. The NT-H1 is a good middle ground; won't last forever, but won't degrade terribly fast and the 1.4ml packaging should be enough for more than one repaste.
