-13C outside..
It died a few times because it was too cold, no lights at all when I reboot..
My box insulates for noise and vents the heat outside the box, but....
I have removed the hose so that it's just blowing out air into the box and what gets out, gets out so some of the heat is being recirculated and it works okay
