Hello all

CPU temp is at 50° when idle.

Hardware:
VF2 1.2A 8GB
Waveshare VisionFive2 CPU Cooling Fan

Note: No thermal paste or the thermal pad yet applied.

As I do not have experience with those pads, so advise would be greatly appreciated

TIA

Without pad or paste, you create a tiny gap between the CPU and heatsink, which when the CPU was hot enough, the small gap become heat insulation.

In short, please put a pad or apply paste.

Paste is better, but I prefer 2 mm thick pad with double side glue to maximize the contact area on the elevated center and also the rim area.
