Review on SoundOriginal 12VDC Brushless Blower Cooling Fan - Ideal for 3D Printer, Humidifier, Aromatherapy, and Small Appliance Repair/Replacement (x1 12V) by Damien Krzywicki

Purchased to replace the fan on my 3D printer. I've tried 5-6 cheaper ones and they always have the same problem: they are out of balance and vibrate a lot. This is not good for the print quality as the fan is attached directly to the hotend and also makes it very noisy. This fan looks much better and doesn't rattle at all. It doesn't move as much air as the cheaper ones, but it still does the trick. It's definitely worth spending a few bucks more than rolling for cheaper ones over and over again.
