Wathai 40mm x 20mm 12V Dual Ball Bearing DC Brushless Cooling Fan for 12 Volt PSU Replacment, DIY Small Electronic Equipment Cooling

案外静音。 風力は強くはないが、弱くもない。

Old fan made a lot of noise. New fan is silent.

I bought this fan to replace an intermittently noisy one in an automotive battery charger. This fan is quieter than the original and has better bearings (ball) that I hope will last longer than the OG. It fit exactly in place, the wires reached the circuit board and the best part of all is the connector fit too. So it was pretty much literally a drop in replacement that worked perfectly on power up. I am, of course, a very happy camper.

My TP-Link er8411 router suffered a broken fan in transit and these fixed it right up. I did have to reverse the black and yellow wires on the fan’s plug. Apparently TP-Link uses a standard fan connector but not a standard pinout. These fans are quiet enough. They are slightly audible when running but cannot be heard with the door to my network closet closed. Installation was simple. The fans come with mounting hardware but I just reused the hardware already in place. The quality seams decent. Not the highest quality but not the worst either.

This fan is reasonably quiet and I've used it to replace one of two aging fans in a Kobolt battery charger. The old fan rattled and squeeled as it started up and I didn't want to risk overheating the circuitry so I bought this one as a replacement and it fit perfectly. Very happy to breather new life into an otherwise expensive piece of equipment. Works great, good flow and low noise.
