DISCLAIMER: I do NOT recommend this for anybody who isn't confident with their hands and are worried about their warranty. I've had plenty of experience working with devices and have means to get another Switch 2 in-case this ended up breaking (thankfully it hasn't and is still going strong even after 5 straight hours of gaming). And before people ask if there's any benefit, this tech youtuber who is using the same thermal paste as me saw significant reduction in noise for their OC'd Switch 1. Also, here's a lab test showing how good of a thermal paste the PTM7950 is compared to other high-performance thermal pastes out there.
Noise levels on a heavily OC'd Switch 1 after new thermal paste application
After watching a number of Switch 2 teardowns, it seems the thermal paste/putty that Nintendo uses is the same as the Switch 1 which will degrade and dry out after about 1 – 1.5 yrs and will result in higher fan noise. I plan to prevent this by using a high-performance thermal paste (PTM7950) and thermal putty (Fehonda LTP-81) application.

Takeaways:
– There's plenty of care needed to open Switch 2 — lots of screws, components, and wires to keep track of and not to mention the sticker adhesives on each side
– PTM7950 is used industrially in cars, servers, high-performance LEDs, etc. so it's meant to last a very long time
– I notice the fan is spinning much slower and is quieter even in docked mode and the heat coming out the vents is way hotter, meaning better heat transfer.
