    Hi,
    I bought a used Nintendo switch that has an overheating issue. The previous owner told me that he tried to change the fan but it didn't work and, sure enough, the new fan he installed doesn't spin at all. He suggested that I could try changing the heat sink. What do you guys think ? Is it a motherboard issue ? Am I out of luck ? Thank you.

    Either the connection to the fan is broken (then pin on the motherboar or the ribbon cable itself) or the rotor is having problem.
    As far as I know, you don't open the Switch fan to change parts, you just replace it. So, if you already tried different fans and none is working, the connection from the motherboard may be the problem.

    Is there any evidence of soldering near where the ribbon cable attaches to the motherboard?

    If the connection from the motherboard is indeed faulty, is there a way to fix it other than changing the motherboard entirely ? Also, can you confirm that the heat sink has nothing to do with this ?
    I haven't opened the console myself and I'm thinking about sending it to a repair shop but I need to know what to tell the shop guy.

    You could also check that the metal shield on the inside is straight and not bent. As if it's bent it could be blocking the fan from spinning.
    Debris inside the fan/heatsink could also do the same.

    Disconect the battery,disconect the fan, test if the diode next to fan is shorted to ground on both sides(on some revisions is not present), if is shorted , remove the diode and test, if is not shorted connect the fan and test again the diode, if now is shorted the fan is faulty.

    Thank you but I don't think I'm going to repair it. I'll see if I can sell it as is. Thank you for your time and help.

    You don't happen to own a tri-wing screw driver? It can just be blocked by something.

    Ah dang it. It's often super easy to fix the fan in the Switch. You can't get a hold of a triwing? Bonus after opening it you can change the awful thermalpaste that Nintendo use.

    What bothers me is that the previous owner told me that he changed the fan already. Now the only thing I did related to electronics is build a PC so I'm not confident enough to do this repair. If i knew for sure that it was just a matter of replacing the fan I'd probably have done it, but i have no guarantee that the problem isn't from the mother board. I mean, if it was just the fan, then surely the previous owner would have fixed it by replacing it, right ? That's why I prefer to sell it.

    If there is no soldering involved. Opening the Switch is super easy. You just have to be careful with the sdcard reader.

    But i would have to buy a screwdriver for 10 euros with no guarantee that I'm capable of repairing it ¯\_(ツ)_/¯
