Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown)

used two for a gpu enclosure

My Ender 3 PSU fan outputs 24v and is a 2 pin and its around 10mm deep while this fan is 12v, 3 pin, and around twice as deep. Cut the old fan off and use its wires. Use red and black, attach to a buck converter, 24v to 12v, and I put the fan on the outside since its too big to fit inside. I pointed the fan to blow air inside for better cooling but just have to make sure nothing blocks the fan or gets into it since its not protected there. Factory blew out. - Edit, I switched it around to blow out. It got kinda hot, though I did hot box it for a 30 hour PETG print. Blowing out has been working fine for my test prints.

Using to replace the very loud fan that came with the forced air adapter purchased for used tesla. Much quieter and still staying cool.

Very quiet with adequate airflow.

Very very quiet even at full speed.

I bought it to do a little engineering for a cooling issue. Works well. When on full and not in a case (which mine is not) you can still hear it. When on low voltage you cant hear it but then its not pushing much air.

Ultra quiet when used with the supplied ultra quiet resistance cable. It also slows fan down but not excessively. I used two of these in a push-pull configuration in a fan-noisy oscilloscope and it cut the fan noise down to the point I cant hear it over the computer fans anymore.

I have found that the Noctua fans are very quiet while running.

These are a great replacement for the fans on my off-grid inverter. They have always been loud, but lately the bearings have started to wear, and they sounded like a jet fighter taking off. These Noctua fans are much quieter, and the noise is easily covered by the fridge and other equipment powered by the inverter.

I am very impressed with the quality of the Noctua fans. Quiet. Well built. I have both 60 and 25 mm running in my 24/7 computer and it is nearly silent.
