75mm USB Blower Fan with 3 Speeds Control, 7515 5V DC Brushless Turbine Turbo Cooling Fan for Helmet Laptop 3D Printer Ventilaiton

I bought the GDSTIME 75 mm USB fan to keep my Mevo camera cool during longer recording sessions, and it works perfectly. The fan is compact, quiet, and easy to power via USB. It moves just enough air to prevent overheating without adding noise to my recordings. Installation was simple, and the included screws helped secure it in place. Great little cooling solution for small electronics!

I happen to love centrifugal cooling fans because they move air in a very controlled manner and do so very quietly. I use these on various applications within my networking and equipment racks to keep things from overheating and they just hum along very smoothly and quietly even at full blast. Only caveat is you get lower CFM for the size of the fan compared to a box fan but because the air is directed in such a concentrated way it solves thermal issues from specific processors far better than a standard box fan and without the crazy noise and vibration.

These are great little fans. They will surprise you with the huge airflow. They work great with solar panels. Low power, and they have nice mounting holes.

I have my laptop wired to a monitor, keyboard/mouse from inside of a desk drawer. This fan mounted perfectly to the drawer to exhaust the built-up heat and comes on via the laptop's USB when powered on. I had to extend the wire a bit, as the wire that it comes with is pretty short at about 6" or so. My gaming laptop now stays cool to the touch after adding this fan. Before installing, I had to at least pop the drawer open a bit to vent the heat out, and you could feel the heat dissipating from the drawer. Great fan, it's just a bit loud for as small as it is. EDIT: I added an inline controller to be able to adjust the fan speed level. I figured I don't need this thing running full bore and being so loud all the time, but unfortunately this fan runs the same speed and loudness from 3v to 5v so there's no turning it down.

I put this in my travel kit to create some air circulation in hotel rooms. It's compact and the "blower" nature is perfect for creating a little bit of circulation. Putting some hot glue on the wires to keep them secure / safe, especially if it will be moved around, is a good idea. And in my use case, I used 1/8" neoprene to line the back to keep it from moving and making noise during use. I'm not using the speed controller. Even on high, the sound is fine. In fact, in my use case, having some "white noise" is a benefit to mask other hotel guests. BT recommended

The fan works, moves a satisfactory amount of air, and makes a modest amount of noise. It is slightly unbalanced, but it should not be an issue for most applications. I was disappointed that the speed control was missing, even though it is pictures and listed in the description.

2nd purchase of this fan and they're both great. Using fan for a Stormtrooper helmet. Small,Quiet & works well. No noise interference with helmet mic system. Really like the 3 speed USB switch extension included.

Good product, as described. Mine came broken and the company was very responsive and got everything resolved same day. Super awesome !
