Hello there, sorry for bumping the thread up but I've also been experiencing the same Switch overheating issues for the past few months, especially when docked in. I recently got the overheating message which caused to system to go to sleep mode.
I've been monitoring my temps for a long while now with the Tesla overlay, here's an example of my high temps readings on something like Pokemon (still docked):
CPU [62%.63%.60%.39%]@1020.0
GPU 86.0%@768.0
RAM 2888/

TEMP 76°C/69°C/60.0°C
FAN 100.00%
As you can see, they are quite high and are still pretty much going up until the "tskin" threshold I believe (63°). For the record, I do not overclock at all, and the dock is not enclosed whatsoever. It "
seems" to be fine when i'm on OFW but I can't be 100% sure with no monitoring tools. I repasted and cleaned (barely any dust tbh) my system a few months ago, but that did not seem to do anything. The fan seems to be working well, even though it is not particularly as loud as I would have imagined especially at 100%? I kinda have to be really close to the Switch to hear it a bit.
So is reinstalling CFW from scratch worth the try? It seems to have worked for OP but it is kind of a pain to redo obviously lol, the formatting, EmuMMC and so on. But the thing is that I feel that I've been getting these issues since i've put CFW on my Switch when I think about it, but I don't know why it would be related to that. On the other hand, the culprit could be the fan not working at its fullest...?
I would love to know your suggestions, and especially feedback from
@Nano_G4 to know if the problem still kicks in nowadays.
