GDSTIME 75mm X 30mm USB Blower Fan with 3 Speeds Control, 5V Powered DC Brushless Turbine Turbo Cooling Fan

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 use this for a custom project. It’s the perfect size to fit in the action of my rifle so when I’m target shooting, I hook this up inside the action and it blows nice cold air down to barrel to cool it off.

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.

Powerful little fan! I didn't need it for a computer or 3D printer. I have used these to make kegerator tower cooler fans, and they work perfect if you use them correctly. I actually used one most recently to keep cool while sleeping when the power was out. Hooked it up to my power bank and it kept me cool all night! I could think of a thousand uses for these little fans. Great product, and quiet for the amount of air it puts out.

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.

Great little fan! Blows nicely and always works when I use it! Had it over a year now.

I bought two of these for the inside of my mando helmet I wear during airsoft. The fans were well sized and only a bit loud because they were in my helemt and the sounds echo but not loud enough to affect my mic and amp that are in my helemt to project my voice. Unfortunately my wires came disconnected but I think that was due to the nature of me removing my helemt. I'm eating 5 stars because the sound was low, thin profile and blew really well with both fans going. Even worked well with just 1 blowing. Will be ordering more for a more terminate install into my helemt to protect the cords from disconnecting.

These things are a life saver when it comes to cosplay helmets. I ordered two and they help out so much. I used them for a Mandalorian helmet and they worked great. They are already wired for standard USB, so i just rigged them up with two small 5v battery pack chargers from a dollar brand store and they lasted hours before the batteries drained. Small enough to hide anywhere in a cosplay helmet, yet still the right size to help move air around to keep cool. I did a convention in mid June and had no issues with the help of these fans. Highly recommend.
