The reason for the use of thermal compound is because surfaces (the top of the CPU and the bottom of the heatsink) have imperfections.  When imperfect surfaces are pressed against each other, the scratches and indentations remain filled with air.  Air is a poor heat conductor, so that decreases the cooling efficiency.

Thermal compound is a soft paste, so it easily fills such microscopic cavities and gaps, and conducts heat much better than air (but not as well as metal).

That is why you want to use the thermal compound, but you only want to use the least possible amount.

Does your desk have a back side? If the back is open, you could move the desk forward a bit (towards you), so that there is a gap between the wall and the desk. That's how I have my bench. It helped a bit, but now there is a hole that cables come up through, and a lot of air flows through there.

Also move your computer forward (away from the wall), while leaving it under your desk. A space for air to move around a bit will help get rid of heat.

but also a meter which will continuously say 25° C, I don't know why. My computer has no reading for power supply.

mebe air temperature??

Use full sentences please, and read the whole post that you quoted from again. I'm not sure what your question is, but I think that the answer is in that post. If it's not, ask again (full sentences).
