I set this up because my Switch would overheat and stop working as soon as I docked it. I'm selling it now because I have a Switch 2 and no longer need it. When I ran this at maximum, the noise was intense, but the console, which used to shut down after 10 minutes due to overheating, stopped doing so completely. This is recommended for those who are struggling with overheating but don't want to buy a new Switch, or for those who just want to use it as a stopgap until they get a Switch 2!
