GDSTIME 60mm x 15mm USB Blower Fan w/ 3 Speeds Control 5V DC Brushless Fans

It had good air flow but even on the lowest setting, it was too loud. If it was a bit quieter it would be a good fan. It did have selectable power settings which was nice.Had to return it because of how loud it was.

Works great to cool my equipment

I use this fan to maintain my aquarium cool and so far it does not disappoint gets loud but at the cost of good air flow no kidding it makes ripples on the surface of the water and brings the temps back to normal in less then 10 mins! Only improvement that can be made if at all possible is to give two options one short cable the other a long cable since the length out of the box Is pretty meh.

OK, so I use an iPad with the M2 chip for in flight navigation (as most smart pilots do). Problem is: the iPad gets smoking hot crunching all the information Foreflight uses especially ADS-B traffic and weather, which is a miracle in itself. It gets so hot it shuts itself down, of course at the worst possible time. That said: I modified an iPad knee board to mount 2 of these blowers adjacent to the backside of the iPad, blowing cool air across it. Problem solved.

The computer desk I have has an enclosed cubby for the PC. I took the door off but the heat still built up in the cubby area. I have two fans on the inside top of my computer blowing heat out. This little fan sits on top of the computer case and pushes the heat out of the cubby and that did the trick.
