I bought this then saw they also have a 140mm, so I bought that too, but only need one.
I got mine from Amazon while in the US.
I have several of their fans and they work very well, but since I am going back to the US I need to get rid of the ones I don't need.
I'm not sure that I ever used this one, but it's possible. No dust.
They are made as cabinet coolers, but I use them on my desk to keep me cool.
Hi/Med/Lo/Off switch and can be daisy chained.
Meet in person with CASH at Gwangmyeong Sageori Station (광명사거리역) line 7.
