This will probably void your warranty, so do at your own risk. But found no warranty void sticker anywhere 🤷‍♂️

Well, for all those who dare and want better temps, this is what I´ve done. Repasting. From my point of view, it is a thing that every owner should do after some time.

Let´s cut to the chase. First thing I tried on my new 14" thin and light was stress testing. These cheaper laptops are known to not to have the best cooling in the industry. Most of the time, it is not an RnD problem, but the cutting of corners to make the manufacturing cheaper. And one of the most simple things to do, is just a simple repaste with quality paste…so I chose a paste that has good thermal conductivity, is safe to use (non conductive) and lasts a long time, so you don´t have to do this every year or two.

To the stress testing.

I just used 3Dmark 20 loops TimeSpy stress test.

Ambient temp. 25°C

First run in normal mode 97% stability maxed out at cca. 91°C, the chassis gets really hot.

Second run after cooling down the laptop in performance mode 97°C and 80,4%, test not passed. Really hot chassis.

After repaste with PTM 7950:

Ambient temp. 25°C

Normal mode over 97% stability, avg. temperature went down to 80°C (according to 3Dmark 76°C average)

Performance mode 88% stability, test not passed but definitely better, and 87°C on average.

Normal mode idle:

On AC 42°C

On battery 36°C

Conclusion:

Easy job. No hidden screws under rubber feet. Three screws holding the heatsink.

Definitely an improvement over stock paste. The chassis does not get boiling hot.

While gaming on performance mode 80-81°C stable.

Normal mode high 60s to 70-74°C peak. 70°C avg. most of the time.

In normal use scenarios the fans don´t spin up so often. And on battery it is dead quiet.

P.s: Used cheap Chinese GD900 paste on the voltage regulators, that I have in the fridge, and use for my desktop. A surprisingly good paste. Better than the stock pads. If you want to use thermal pads on the regulators, I recommend 0,5mm max thickness.

SSD slots. Just reposition the SSD to the second slot under the ribbon cable next to the fans. The palm rest is cooler under stress and the SSD gets actively cooled by the fans. The heat distribution is more even and not concentrated on the left side.

Have a nice day everyone.
