🌀 High-Speed Brushless DC Cooling Fan 24V 40mm x 40mm x 10mm - Ideal for 3D Printers, Humidifiers, Aromatherapy, and Small Appliances (2-Pack) Review

I was looking for a small, simple and efficient fan that could be mounted outside of my laptop's air vent to dissipate heat when my laptop gets hot. The fan plugs into a USB port and is small enough to be taped next to an air vent. I wish it was a little quieter, but I can easily turn it off when I'm on a call. I could probably just cover it with a lid to quell the white noise.

Just received. Have 2 modes - on and off and as described! Plugged into my wireless gateway (USB) and placed directly on top with airflow away from the device, I can feel the difference! The gateway stays much cooler! The other previously plugged it into the USB port of Smart TV and only paid for the vent. Fan size, let's say you take a poker card and roughly cut it in half. Small but it will help your small electronic devices run slower and most likely last longer! Will update if necessary

They match the Ender 3. They seem to be just as fluid as the original Creality brand. At first they are calm. Much quieter. Unfortunately, a small dent on the fan blades and it's over. I was testing the motor and accidentally hit the blades with a screwdriver and it got loud. There was nothing I could do to shut him up again. It's ok I bought two but hit the blades again now I'm back to the noisy fan. Still better than stock but nothing like the youtube video. The case also adds sound to the…

I figured if I wanted a hot end quiet fan I would have to stick with a low CFM Noctua fan on a buck converter. Not true! That's three times the airflow of the Noctua A4x10 and no louder than the A4x10. Most of the fan noise in the video comes from the cooling fan and the PSU fan. I am very happy with this fan. I put one on my Ender 3 which will soon be a shifter cable and my Voron V1.8

I've previously found this to be very noisy on my Ender 3 3D printer. When choosing the Dual Unit, I seem to have my choice of going from a 24V fan to a 12V -Fan switched and did not understand it. So apparently the 12V to 24V fans are still running, only the fans sound like a tornado or a jet about to take off. Just connected and installed a 24V fan. It's about the same, if not slightly quieter than a regular fan. Change to 5 stars was my mistake

very good bearings. Bought 24V to replace a fan on an ender3v2 motherboard which is rattling horribly after 3 days. it does a GREAT job. The standard fan says 7000 rpm, this one says 6800. It has a much larger hub for the bearings. But I couldn't see much of a difference with airflow. direct plug exchange. will probably buy a second one for the extruder fan.

I was trying to find a fan that moves enough air and runs smooth and quiet. This is this fan. The fan runs at 100% on a 24 volt system. You can listen to the noise and hear how quiet it is and see the napkin strip she moves. The printing speed was 12 mm/s. I really like these fans and now I have backups. Most of the noise you hear comes from the power supply fan, which is located to the right of the printer.
