Okay, I've been watching lots of YouTube videos about switches and I've just made myself more confused. Managed versus unmanaged seems to be having a GUI versus not having a GUI, but why would anyone want a GUI on a switch? Shouldn't your router do that? Also, a switch is like a tube station for local traffic, essentially an extension lead, so why do some have fans?

it depends what you need it. If you want a "stupid" tube station for local traffic, then you want unmanaged. It needs less power. If you instead want to have multiple VLANs, which are separate virtual networks inside your network, you need managed. Then from the GUI you say "port 8-12 are for VLAN 5 which is 10.0.0.1/8 and does not have internet access, rest is normal LAN". If then the switch has lots of fast ports, then it needs lots of power to manage the communication, more power means more hot, and more fans.
