So I've had my switch for years (genuinely forgot how long ago, pre lockdown) the last few months the fan has started to spin up to full at idle, I have checked temps on the overlay, soc is good, 25~30°C but pcb temp is always at least 60, but i am yet to see it go over 65 even after extended gameplay.

The fan immediately stops if I put it into sleep or turn it off, reboot etc.

I have taken the switch apart with new thermal paste etc and have cleaned it out of dust etc.

The problem seems to be with atmosphere as the fan does not spin or at least is very quiet in hekate and ramps very fast to 100% during boot of atmosphere. Im unsure as to what the issue could be, I have re-installed atmosphere and no change.

Any help would be appreciated.
