The only purpose of the computer is to work as a electronic dictionary (my main computer isn't there where I need the dictionary) so I don't want to take pains with it. I just asked if it doesn't need the fan because it would have been an easy and fast way to muffle it.
Gryphin:
Hey thanks, that's a good idea I haven't even thought about it

As I said the computer is only an old 486 and I just took it from the storage so there's nothing important to backup.
Geoschmo:
Thanks, I'll check those. Perhaps I'll also remove the safety grid from the front of the fan.
Baron:
Hmm, I think a new special silent power supply to an ancient computer would be a bit exaggeration, even if I'd manage to found one somewhere.
Thermodyne:
Do you think it will still cool enough?
