Anybody know about computers?

[Argo]

I bought a new computer and I'm trying to figure out if it's working normally or if I should try to send it back. I bought a solid state drive computer. I've never had one before so I don't know what's normal for this kind of computer. It's pretty quiet most of the time but if I do something like run an antivirus scan, download or upgrade software then the fan runs very loud and the computer gets hot. I already ran diagnostics provided by the manufacturer and it found nothing wrong. The ventilation should be fine because it sits on a wood desk. When I upgraded the bios it sounded like a tornado. Is this normal for this kind of computer? 

I realize this is a little off topic, that's why I posted it here.
