Can I briefly put my laptop in the fridge if it is too warm?
That's fine
If I were not affected by the temperature difference, water could form on the electronics or on the outside
Can you read that someone wrote this out and let it rest is the stupidest thing you can do when something gets really hot 80-90 degrees or hotter why should you turn that thing off? So the cool longer prefers everything to end load and run something idle then the fan runs on
NO! Better put an egg box under it the next time you use it there's room and the air circulates better
Correctly
To be honest, do not think that's a problem.
