    If you have a hardware issue with temperature indicator and the fan will not spin.
    You can permanently power the cooling fan. The NSW dosn't check faulty fan speed.

    You can use V3.3 from Nand point, it will give enough power for trinket & fan, too.

    Warning Note: Dosn't connect the flat cable from the fan back to the mainboard. Cut it away!
    Remember also: Permanently power fan will drain your accu but better as to dispose NSW.

    This is cool but there's no need to take risk.

    add this to atmosphere/system-settings.ini to enable max fan speed.

    str!"[[-1000000, 40000, 255, 255]
    -1000000, 40000 these are temperature 40000 = 40C
    255 is the speed, 0-255

    Code:
    ; Unlock fan speed (dock speeds)
    [tc]
    tskin_rate_table_handheld = str!"[[-1000000, 40000, 255, 255], [36000, 43000, 51, 51], [43000, 48000, 51, 102], [48000, 53000, 102, 153], [53000, 58000, 153, 255], [48000, 58000, 153, 255]]"

    Thx to thaikhoa for the post but I'm not sure if you can set under tskin_rate_table_handheld the temperature value to 0c and the cooling-fan will spin back again.
    But you sould try thaikhoa post first, if not the HW Mod will work.

    It will work straight away from booting as the min setting is in minus temperature. Anyway, HW mod always works :D

    If this works, don't go soldering your fan, it's much smaller wires/joint then you think, and easy to break something important.

    Can this be used to have a quiet profile for handheld mode?

    Here and there
    I may be mistaken, but I think it can be done with the instruction: 'tskin_rate_table_console' instead of 'tskin_rate_table_handheld'

    According to SwitchBrew.
    For 1.0.0-4.1.0 FW, the table is: "[[-1000000, 43000, 51, 51], [43000, 53000, 51, 153], [53000, 58000, 153, 255], [58000, 1000000, 255, 255]]"
    And for 5.0.0+ FW, the table is: "[[-1000000, 40000, 0, 0], [36000, 43000, 51, 51], [43000, 53000, 51, 153], [53000, 58000, 153, 255], [58000, 1000000, 255, 255]]"

    But I may be mistaken, so if you don't want to risk it, wait until someone with more knowledge confirms or denies/fixes it.

    This is for handheld so you can adjust to any value you'd like to have. The default settings is 0,0 to be replaced by 255,255 to enable max fanspeed as an example.

    Fun fact that in handheld mode it will never run at max speed (>=58oC) unless max OC with charger for a long period of time.

    This is totally safe, btw.

    use tskin_rate_table_console instead of tskin_rate_table_handheld

    Hell
    Mine is simpler :shrek:
    (and can also be used by those who always want a maxed out fan speed)
    Code:
    ; 24/7 hoover mode
    [tc]
    tskin_rate_table_console = str!"[[-1000000, 100000, 255, 255]]"
    tskin_rate_table_handheld = str!"[[-1000000, 100000, 255, 255]]"

    This is great! My Switch used to be very hot and slightly bent after playing docked, with this little mod the system is perfect! Too bad I can't use it to play Splatoon online on Sysnand.
