MacBook power supply lies between two mattresses and heats up, is it harmful and dangerous?

Question

Power Supply

The bed consists of two mattresses lying in a joint in the same plane, between them the most convenient place is created for finding the laptop charging to which it is constantly connected, it heats up there and is not ventilated, but never turned off, there seems to be protection against overheating. How harmful and dangerous is it to keep it working in medium mode (the laptop heats up the charge but does not even turn on its fans, because it's normal browsing and watching YouTube)? It will be a pity if the charging fails, it hurts incredible money.
Due to the originality of charging and the use of RCDs, plus it only heats up when I'm nearby and the laptop is turned on, so I think the likelihood of a fire is not so great. The rest of the time they sleep.

Answer 1

1) RCD does not protect against fire, only against current flowing to the ground.
2) each extra degree reduces the service life of charging components, primarily capacitors, by how much? but who knows, of course you can look at the datasheets of a specific batch of capacitors in charging, usually they write something in the region of 2000 hours at 105 degrees for good ones, the figure comes across 10k hours.

Answer 2

Well, make a charging case out of something (a plastic bottle, a tin can, etc.) with holes for charging to provide a gap between it and mattresses for ventilation.
The lower the temperature of an electronic device, the longer it lives, I support Vasily
