I believe that model does need to be cooled by water.
I have had this one since October and it hasn't failed me except once.
I'll preface my remarks by saying that when I had the problem with it the other day the humidity was at 100%. There was condensation over everything.
This, I believe, caused moisture to accumulate on the internal circuitry. This caused a malfunction in the auto-shutoff feature.
I attempted to duplicate the malfunction, the next day, in a video to send to manufacture but everything worked as designed. The only difference was the humidity was at normal levels.
The lesson learned for me is to never trust the auto-shutoff feature. I need to remain near the air gun when it's getting close to full. Then shut the compressor off if the auto-shutoff feature doesn't work.
I would adopt that practice no matter what sort of air gun compressor I have.
VEVOR PCP Air Compressor auto-stops at preset pressures, works with 12V car batteries or home sockets, and has built-in cooling for paintball, scuba, and air rifles.
