LOL, I think in all full switch disassembly videos it clearly shows RAM has no cooling on them... ppl who do a full custom cooling mods are the ones who add memory cooling...
It's not like its even necessary to cool the memories because they are not high frequency low latency memory that produce a lot of heat, even most PC GPU's with like GDDR5 don't have cooling on them...
However in my opinion the cooler it is the better, so when I will open my switch I will do a full cooling mod, I will try to cool the charging chip and video out chip too (most dead switches out there are mostly all the time a fault on either of those chips and its a pain in the ass to remove them and solder a new one even though they cost almost nothing, it needs to be done with a heat gun which I'm not comfortable, I only have the soldering iron), add thermal pads on the ram, remove the copper sheet and use direct contact from the die to the cooler using Kryonaut thermal paste, add a huge amount of Artic MX-4 all above the heatpipe for max heat transfer to the backplate and maybe even later I will think if I will order a custom back plastic transparent case and make a big hole near the fan for maximum airflow...
Since I don't use my switch I still haven't modded it, only modded the controller quite a few time ago with a ON\OFF button on the joy-con for RCM...
..................Will edit results once I finish transferring over everything to a new SD card. I play heavily modded skyrim at max OC. The switch sounds like a jet engine and gets fairly hot. Hoping this will help a bit!
Humm, from what "
swutch" posted his consoles had nice temps at max OC, though maybe it was just Trials game that wasnt enough to produce a lot of heat, no idea... Hope he can test Skyrim too at full OC and post the temp results, but with the temps at max OC he shown at leat on trials the console shouldn't ever be jumbo jet loud...
I'd recommend you open the switch and verify the die if it made full 100% contact with the cooler plate as some cores might not be having good contact and might have hot spots, that is if your not too lazy like me
...
Or at least a few time from now if you decide to clean your switch definitely verify if the thermal paste applied to the SOC die really made nice full 100% contact with the cooler plate.
