Hello!
My nintendo switch’s fans are running on max speed, no matter what, from the moment it is turned on.

I suspect it is something to do with the fan not receiving the pwm signal it needs.

Any help would be appreciated.

You should list more details.
Switch Model
Stock/Softmod/ModChip
If Modded - What Homebrew installed? (Sys-Clk)?

So I replaced the thermal paste and still, it has the same problem, I also checked the cable to the motherboard, reseated it.
Is the M92 chip also related to the fan? I thought it was only for the charging part.
Also the temps are max 42-43c while playing zelda

    Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.

    The phat model had amazingly loud speakers tho.

    @Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

    They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".
  • Veho @ Veho:
    It's a DS Lite in a slightly bigger DS Lite shell.

  • Veho @ Veho:
    It's not a Nintendo / iQue official product, it's a 3rd party custom.

    Nothing special about it other than it's more comfortable than the Lite
