I have now purchased nine computers from Kingdel.  All of them have been solid performers.  Two of them have been running non-stop for almost two years now, and no issues.  This particular model does have a built-in fan to help the system remain cool.  It will only come on when cooling is needed, and will ramp back down once adequate cooling has taken place.  At idle, the computer is silent.  Some of their computers don't have a fan ... for light computing, the fanless design is great.  Kingdel has excellent tech support.  I've reached out to them several times, and they always reply promptly with the help I need.  Very happy, and would definitely recommend to others looking for a new computer.  The footprint can't be beat with regard to size!
