I have an small air pump for my aquarium which is in my bedroom. It’s a bit noisy and disturbs my sleep so I worked out that if I place it in the laundry basket the noise gets muffled enough for me to get a quiet nights sleep.
It does get a bit warm after several hours of running (although I haven’t tested it yet to see hot warm it gets with ventilation.
The pump is sealed and does not have any ventilation holes of it’s own – (though I am not sure how it sucks air in – probably through the gaps of the shell casing.
Was curious is it safe to have it insulated like this or is it a fire risk?
