I installed thermal pads between the body and the copper tubes. This gave me the perfect temperature. The processor heats up slowly, cools faster, and the fan makes less noise. I can also warm my feet in a cold room.
Why didn’t the manufacturer use them? Maybe I’m missing something?
P.S. I used 0.5 mm thermal pads and removed part of 0.5 mm quads on fan body.
I bought a thermal pad 35х35х0.5 mm. Divided it into 3 parts. And placed as shown by the red rectangles.
After assembling the thermal pads barely touched the body, so I removed the squares indicated by the yellow crosses. They were pasted in 2 layers and I removed 1 layer.
I bought it at a local store. You can use any thermal pad, the main thing to match the thickness. Also, I advise you to first try to install something 0.5 mm thick to make sure that the distance between the copper tube and the housing is 0.5 mm or slightly less.
