GE-75 CPU+GPU Heat - 2 months after repaste.

Hello good people of NotebookReview!

I have a GE-75 with 9750h & 2070.

My throttlestop configuration is as follows,
-166mv cpu core
-138mv cpu cache

6 core active 38
5 core 38
4 core 37
3 core 38
2 core 39
1 core 40

TPL turbo boost long/short max 38W.
Speedshift 8.

These are my gaming settings, however, I used to have great temps after repaste.
I repasted with Cooler Master MasterGel Maker, used B0B's advices about triangle mount repasting, quantity, air-gap and such.

But here I am after 2 months, I am having temperature issues. My apex max. temp was around 85c. Now it is around 94-97. The ambient temperature is the same. I can't really figure out what's wrong.

2070 is clamped at 1000mv. It used to be around 75, now it is 85.

Any ideas why? Could paste go bad within JUST 2 months???

I am not in EU or USA, can't get my hands on Phobya brand pastes.

The best I can do is noctua nt1 or 2, mastergel maker, arctic mx-4

I know, these are not thick pastes and not very suitable for laptop use, but these are sadly my options.

Any ideas why temps are not what they use to be?

Thanks.

Couple of pictures, uneven temperatures and more cringe pics for your enthusiast taste

 

If the followings happened the heat conduction will be affected:

1. Surface of the copper plate oxidized and affect the heat conduction, sanding needed.
2. Paste has dried out.
3. Liquid in the copper heat pipe has dried out, new heat module is needed.
4. Dust on the heat fins, cleaning is needed.

I usually just swap the whole heat module for a new one once per year to avoid spending too much time on this.

 

Thanks for the reply, Hackness. Notebook is 4 months old. I clean it monthly using high pressure air. I doubt it is 1,3 or 4. Though there is no logical explanation why would a high quality paste go bad in just 2 months...

 

Use a thicker paste as ICD or Phobya Nano grease Extreme with a heatsink with not adequate pressure on die or uneven heatsink(thinn viscosity paste will pump out regardless if it’s high quality paste).

 

I have tried 4 thermal pastes in this laptop (Ge75)

- Kryonaut
- Coolermaster Mastergel Maker
- Phobya Nanogrease
- IC Diamond

None of them except IC Diamond lasted more than a few days/weeks: CPU temps were fine the first days but after a while, they began to increase and reached 90c+ when gaming.

IC Diamond is giving me 83c max and looks like it's gonna last forever.

If you have problems with your regular paste I recommend that one based on my experience.

 

Hey, i think that happened because of dust on the heat fins, i had similar issue with my GE73VR, after few months of usage. it can be fixed easily just unscrew the small screws (3 or 4 small silver screws) on fans and clean, hope this will help you

 

How about the clean-up on the heatsink, best to take it off to clean it thoroughly with compressed air. Don't blow the air into it while it's still on the chassis as the dust has nowhere to escape except the internal.

 

@Aeronaut88 Check the FIVR tab in throttlestop and see if your undervolt is hook,on the right upper side of the square board. If you don't see your negative numbers of the cpu core and cache, you are affect by the "plundervolt" fix. (by the Bios update and or by windows update...).

 

Why have you set the CPU and Cache at two separate values? Speed shift will use the highest turbo multiplier as its clock limit with throttlestop, as the program has only a basic setting format just to activate it and gives the OS priority over ISS after. Mind posting a screen shot of your settings?
