💨 Compact and Powerful: 2 Pack Wathai 30mm x 10mm 5V DC Brushless Cooling Blower Fans - Optimal Airflow for Ultimate Cooling Review

Used to replace a defective standard fan in my one year old JGAurora A5S. Fits right, no problem. Runs quieter than stock. Having 2 packs is a plus. However, the wires are about 3 inches shorter. I end up cutting them off, cutting the wires from the old fan (along with the connector) and soldering the wires to the new ones using heat shrink tubing for insulation.

I use one of these to cool a custom rig with a single board computer. Actually runs on 3.3V and not 5V as I don't need the full bandwidth of the airflow. At this voltage they consume about 140 mA and are very quiet.

These fans move a lot of air for their size and can get noisy at top speed. but it is a fan. they make noise. I got the revs down to 1250 rpm and the noise is barely noticeable and still delivers plenty of airflow considering how small these things are.

For use with a welding helmet to prevent lens fogging. Smaller than most fans but overall they don't seem to miss my lens.

Nice little fan. Good for small projects. When assembling my project, I broke the wire at the soldering point of the fan. Easy fix if you have the tools. It just has to be handled with care.
