I have never heard it make a sound at all. I have never heard a fan sound. Nothing.
When you say virtually silent, what do you mean? A great deal would've been the AMEX £50 Apple cashback, and apple educaitonal pricing mac mini, you get a pair of airpods too works out to £579 or so. Then again I've got loads of earphones wired and wireless and I never even use them couldve sold them though oh well
I've recently been using mine for retroarch, it is an absolute beast, I've been playing games upscaled to 4k resolutions without a hiccup. I use it primarily as a plex server and it's never topped out yet. Again it's a little beast. It's virtually silent whatever it is doing, never gets warm. 8GB ram sounds like little compared to my desktop i7 pc with 32GB I suppose it is... but it still runs rings around it with 8GB so apple have done some impressive tweaking. Anyone holding back should just get one, they are very impressive.
does this thing have a speaker jack? i have some old dre beats touch 2 that i use with my mbp
