> 3 dayFan only spins after 340W of power draw so in general, the fan wont spin and the unit is silent. 10 year warranty is a great touch too.

> 3 dayThe product is fine, but do not purchase from this item from GREZ LLC, they will charge you more than double the average price and their returns service is the worst Ive ever experienced.
