Grow clip fans for the grow tent

[sballo]

I have two clip fans (with usb cable) in my grow tent which I think are quite ok but there is a problem, they automatically turn off -though they are constantly plugged in - after a while which means that I need to switch them manually back on.

Any idea why?

Sounds to me like they have an automatic shut off so as not to overheat.

It might be!
I will need to buy new ones!
