Fans are already going " as needed" if your system supports it.

It's not because you are not using the computer that it means that it
doesn't use power (and produce heat), hence why the fans work even if
your computer are idle.

Do you know what hibernate means ?

https://en.wikipedia.org/wiki/Hibernation_(computing)

Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh
computers) in computing is powering down a computer while retaining its
state. When hibernation begins, the computer saves the contents of its
random access memory (RAM) to a hard disk or other non-volatile storage.

So yes it does cut your Internet connection.

It wouldn't be a good choice to turn off the fans as you'll be causing
your CPU temperature to rise and this could damage it. Even if it would
be possible, something that I have doubt. As there's some self
protection enabled in the management system.

Maybe you are playing in something you don't really master the ins and
out of the consequence of what you may do. And this is proven by the
simple sentence that *hibernation cut Internet*. Unless you have a good
reason to risk frying your CPU then leave it alone.

Or buy a system that doesn't use a fan, like the low power, low thermal
emission CPU used in laptop with only passive cooling (heatsink).
