Purchased this computer for its small size, which fits my desk so I can have more space to put other stuff for testing. Unfortunately, because of the small form factor and the dusty CA air quality, this unit became overheat after 6 months of use. I have to put an external fan to cool it all the time in order to avoid getting shutdown abruptly.Although I tried to clean the internal fan, but turn out too much work and failed too often to make it running normally.I eventually purchased Dell OptiPlex compact PC with almost double size of chassis in comparing to the Intel NUC. The Dell PC handles the heat dissipation much better. I do not have overheat shutdown problem so far. Look like Dell PC will do the job without the heat problem.
