Wathai 120mm x 32mm USB Centrifugal Blower Fan 5V DC Brushless Motor with Speed Control for Receiver DVR Xbox Modem AV Cabinet Efficient Cooling

The fans work great in my costumes. The fans kept me nice and cool. I love that the cord is long, so I could put the battery pack, I connected it to, in my pocket.

These were great to cool my little minis forum micro PC. I was getting 180° on my M2 drive before and now it's about 95°

PROS: This fan works. Hooked it up directly to USB Power supply and it drew air and will be ready for hot days to help pull hot air out of my computer from outside the enclosure. Comes with a guard to help keep foreign objects from getting caught in the fan. CONS: I ordered the 120MM fan so that I could get a sliding switch controller as I suspected there may be trouble with the button switch controller. Hooking first time using the controller FAN would not work at all. Fan only worked when hooked directly into power supply. Yes I'd buy this again.

Does the job for my car amplifier.

They're blower fans, they worked for the project I had in mind. If you need some more directional airflow these will perform the job.

They have a noise but it's a soothing noise, like air. I wouldn't complain about it and they're nice and slim.

Moves a lot of air for their size. Quite on low setting. Loud on med-high. Grate for keeping amps or electrics cool for best longevity and proformace!

broke after hardly any use unfortunately. cheaply made

Work great for 3d printer exhaust fans

First things first, these things move a LOT of air. I originally purchased the more expensive AC Infinity model and I ended up returning them. These blow more air on the medium level than the AC Infinity unit blows on the highest level. I purchased two for very specific use-cases. One I have attached to a Nighthawk M1 because the thing was constantly overheating which destroys the hardware over time. Even on the lowest setting, the device is now cool to the touch whereas before it was HOT. The second one I purchased to affix to a 12V DC refrigerator to assist in dissipating the expelled heat. In the summer months, these fridges work really hard to combat the ambient temperatures and the internal fridge fan doesn’t move much air. Now I have these things sucking out the hot air which keeps the fridge running smoother and easier.

Perfect, no noise , big enough to cool multiple raspberry pi devices with 5v

This works really well in our RV fridge. It circulates the air from top to bottom and it’s very effective.

this little fan is so cool it usefull at a point i cant live without it! any projects i build i can use this to cool the systems down very fast and it reliable using USB with a spe ed switch 3 speeds on it. Very quiet fan. about 75% less noisy than other same kinda fans
