The effect of thermal paste on MicroPC performance

The screws on the inside portion of my MicroPC hinge come loose, therefore I had to disassemble the whole unit (see Repairing screen flop on the GPD MicroPC).
During this process I also replaced the thermal paste with Arctic Cooling MX-4 2019. I was quite surprised with the result. The thermal paste does affect the performance of the device.

Here is the comparison (left: the original paste, right: the new paste):

Here is the comparision of Windows 10 (left) and Gentoo Linux (right) with the new thermal paste:

BTW, the result on the right is better that all other GPD MicroPC benchmark results.
