    Some temps of before and after would be handy. Also please post pics would be very helpful for noobs. My switch heats up by just playing mario maker in handheld mode.

    On a scale of 1 to 10 (10 being hard) how easy is it for a noob to do this?

    Which method of therma paste you applying? Drop or completely over cpu?

    I'd say it's about a 7. If you accidentally mess up one of the pins near the CPU/RAM You can screw up your switch. Just be careful and it's not too hard, though. And you HAVE to apply the paste to the entire CPU, because of the kind of system it is. Any section of it not covered in paste will be a hot spot and probably fry it. I just used Arctic MX4

    It actually feels like my switch gets warmer after doing this. That might be because of the increased thermal conductivity to the back metal panel, though.

    Shame that installing for example IC Graphite is probably not possible :(

    I want to improve cooling as I want to overclock my switch in handheld for Dragon Quest XI, However after watching the available videos and read the whole thread, I came across some different infos regarding the thermal pads, I have mx4 Paste and arctic thermal pads in all 3 sizes at my home (0.5, 1 and 1.5mm), so i would like to ask the following:

    1. Which thermal pad sizes did you end up using, I am pretty sure abort the 0.5 directly on top of the memory chips, but not sure about on top of the memory chip cover and on the heatsink. Also did you completely remove the copper thing and left it out or not?

    2. Any quick way to check temperature before and after, without running a demanding game for 2 hours? I am not interested in seeing exactly how much it improved, only to see if there is a slight improvement and I didn’t make it worse than before.

    3. Someone tried to overclock to docked speeds in handheld and do you think it’s okay? I know that there is concern regarding battery drain, but I have always a ravpower Bank with me, which should nearly prove the same power as an ac line.

    Mine feels warmer after the mod as well. But since the fans are also quieter than before, and don't seem to spin up as often, I'm inclined to believe that it's due to the increased thermal conductivity.

    the back of the switch why not cut out a round part of the plastic the the fan has better intake it wil drop at least 10C
    you can buy a dust filter ! thats what i did with my ps3 slim ,i dont have waranty so... that and the thermal paste would at least drop it 15C maybe ? i know my ps3 is stable at 40 degrees celcius in game / as you can see the shielding already has the hole ! so why not use it,is it possible to test temps with sx os ?

    sys-clk now supports temperature logs.
    so we can compare values in games.

    5Min in Tials Rising(heavy overclock) and the log time set to one minute (temp_log_interval_ms=60000)
    looks like this on my Switch in original Nintendo Dock:

    I exchanged the thermal paste with Thermal Grizzly Kryonaut.
    The copper plate and the aluminium plate are removed.
    1,5mm "Thermal Grizzly Minus thermal Pads" are on Ram chips.
    And 0.5mm Pads to connect the heatsink with the metal housing

    probably another game is more suitable
    but it was a first try.

    Some people already do that in their Switches... the old cooling mods videos on youtube shows on one of them that he bought a clear case and made a big hole near the fan intake, but sadly he didnt put a dust cover so I think his switch will eat dust like nuts all over inside, though what is important at leats the fan and the cooler at least he can even always clean it without even having to open the console by just touching the fan with 1 finger to prevent it from spinning and just spray air all over the place...
    Yep more heat transfer, so the die should be cooler and the rest warmer...

    However we have to be careful here is that by removing the copper crap sheet we have to make 100% sure the thermal paste covers the entire die and that 100% of the die makes full contact with the cooler plate because there could be hot spots and some cores might not get efficiently cooled...

    I wish was that there was a custom inexpensive full copper thick cooler that would be cooler+back cover all in thick copper and with the exit fins all soldered with the pipes also soldered to the back full copper cover, it would probably even be enough to fully cool the switch portable without having to turn the fans ON, that would save even more battery.
    That's actually not looking any bad if the values are even any reliable...

    Wish SX OS and Atmosphere would add the thermal+clock reports to the home menu like we would play any game, just go the the home menu where we can change the screen brightness and we could see all temps+clocks, that would be amazing and I can't wait till someone adds that...
