Noiseblocker NB-BlackSilentFan XM2 40x40x10mm Silent Fan 3800RPM 14 dBa

I installed this into my Ender 3 max to replace the incredibly noisy mcu fan. Along with a buck converter, the setup was incredibly easy and it works well and silently. It has a nice braided cable and high quality build. If you have a 3D printer with a 24v fan, I would recommend this or rather the newer Noctua 24v 4010 as it doesn’t require a buck converter. This is simply a great product.

Fit the bill properly due to their compactness and air volume efficiency.

I purchased this fan to replace the part cooling fan on my 3D printer. This new fan is as quiet as advertised. The old fan made more noise than my part cooling fan. Now that the hot end fan is silent, I can now hear the part cooling fan, not noisy, just able to hear without the old noisy hot end fan.I would get this fan again.

I wish they have 24v fans for my other 3D printer.

I had bought this for my 3D printer's front cooling fan and it had gotten the job done great! it is small but powerful as well as very quiet. The quietness of the fan doesn't effect the performance of the fan at all and it made my 3D printer wispier quiet thanks to it! I have tried other fans on the market and this is the best, quietest one I have found yet (and the price is not to bad either)! The fan is everything I had hoped for, quality, quiet, and affordable
