Noctua NF-A4x10 24V PWM, 40mm Quiet Fan for 3D Printers and Other Applications, 4-Pin, 24V Version (40x10mm, Brown)

I used this fan on an Ender 3 V2 and did not need to modify anything. I connected it directly to the hot-end fan terminal so it runs all the time. The included adapters were helpful because I did not have to strip any wires myself. This saved me time and hassle. It is very quiet compared to the original mainboard fan. Cooling seems about the same even though this fan uses less power. The fan feels well made and comes with several adapter options. Overall it is a good value and worth the extra cost for the adapters and features.

Noctua is one of my go to fans for PC, so when I went to upgrade my 3D printer, I of course turned to them. I am sooo happy with my purchase. The fan was much quieter than the factory fan that came with it. The airflow and cooling that it offered was superior to the Creality fan. I did have to print a custom unit for the fan to fit, but this was to be expected. Overall, I am very happy with this purchase.

After the second hotend fan went out in less than a year of owning my Ankermake M5C I decided to give this a try purely in the hopes that it would be a more durable replacement. While it's too soon to know how much longer it'll last compared to the oem replacement fans, I have to say that my overall print quality has improved dramatically! All the silly little issues that had me chasing my tail, tweaking settings constantly are now over. Layer adhesion, bed adhesion, bridging problems, elephant footing, general warping... gone. I've even been able to stop using brims or rafts and my supports separate with nearly no post-print cleanup. Obviously, your results may vary but I'm absolutely recommending this fan as the best drop-in hotend fan upgrade if you own an Ankermake M5C. Installation is a breeze using the included 2 wire adapter, a few hex wrenches from your ankermake tool kit, and some pliers to help lock down the scotch locks. Just cut off your old fan's connector leaving enough wire for routing around the extruder gear and connect it to the 2 wire adapter via the scotch locks (red to grey, black to black). If you've never used scotch locks before, remember that it's not necessary to strip the wires, just make sure they're fully inserted into the scotch lock and press the center down as straight as possible. If you get it canted, it could break the scotch lock (others have mentioned this in their reviews). Luckily, Noctua provides 4 in the kit so you have extras for 2 wire applications like the M5C. Otherwise the installation is just the same as an oem replacement and instructions can be found on Ankermake's support site. If I somehow acquire another M5C, I'd do this swap as soon as it's out of the box. I'm that sold. My only gripe is that it doesn't appear that they make a 3010 version to replace my noisy pcba fan. Buy this fan if you have an Ankermake M5C, seriously. Oh yeah, it's super quiet too!

This was a perfect drop in replacement to cool the Sovol SV08 motherboard. The original fan is very noisy and I can barely hear this fan. The entire upgrade added only five minutes to the printer assembly. The original SV08 motherboard fan is wired to 24V to run constantly. It's possible to move the connector to another header that is connected to an output and add a line to the Klipper config file so the motherboard fan only runs when needed to cool the MCU, and PID control adjusts the speed so it only runs fast enough to cool the MCU, but this Noctua fan is so quiet that I didn't bother with PID control. It runs full speed all the time and it's quiet. This is a very high reliability fan, so even running constantly, it'll outlive the 3D printer. I liked this quiet Noctua fan so well that I bought two 120 mm Noctua fans to add forced ventilation to an enclosure I'm designing and building for the SV08 3D printer. This Noctua fan probably cost me 20 times what Sovol spent for the little noise maker that they chose to cool the motherboard, but once you compare the two, you'll know where all of that extra money went.

Runs quietly and efficiently. I was very impressed by the packaging and number of connectors and mounts it comes with.

Great fan for my Ender 3 pro's power supply. It made a huge difference in sound when in operation.

This fan performs exactly as advertised. Keeps my parts cool, and is very very very quiet. Nice long cable,and plenty of accessories to get you connected. I would buy this again.

I replaced the original controller board fan in my Sovol SV08 with this and the results were great. The original fan was loud and distracting and is always running when the printer is powered on. The Noctua was a simple drop in replacement with the included adapter cable to hook it back up to the motherboard. This one is much, much quieter and I'm so glad I installed it.

I recently upgraded my Ender 5 S1 3D printer by replacing the stock fan with the Noctua NF-A4x10 24V PWM 40mm Fan, and the improvement has been remarkable. ✔️ What I Appreciate: Superior Quietness: The Noctua fan operates with minimal noise, significantly quieter than the original stock fan. This enhancement has made my printing environment much more pleasant. Efficient Cooling Performance: Despite its quiet operation, the fan provides excellent airflow, effectively maintaining optimal temperatures during extended printing sessions. High-Quality Build: The fan's construction is robust and durable, reflecting Noctua's reputation for premium quality components. PWM Control: The PWM feature allows for precise speed control, enabling the fan to adjust its performance based on the printer's cooling needs, which contributes to both efficiency and longevity. ❌ Areas for Improvement: Installation Considerations: While the fan itself is top-notch, users should ensure compatibility with their specific printer model. In some cases, slight modifications or additional adapters may be necessary for installation. 💡 Final Thoughts: The Noctua NF-A4x10 24V PWM 40mm Fan is an outstanding upgrade for the Ender 5 S1 3D printer. Its quiet operation, efficient cooling, and high-quality construction make it a worthwhile investment for those looking to enhance their 3D printing experience. ✔ Best For: 3D printing enthusiasts seeking a quieter and more efficient cooling solution for their printers. ❌ Not Ideal For: Users who prefer plug-and-play solutions without any need for modifications. 👉 Overall: 5/5 – An excellent fan that delivers on performance and quietness, significantly improving the 3D printing environment.

Due to their 24V rating, these are advertised as a "silent" alternative to the stock fans of your 3D printer. And yes, they are silent but mostly because they move about half the air a stock fan does. I used these to replace the fans on my Ender 3 and the result was nothing but problems. It doesn't cool the heat sink of the hot end enough causing filament to bulge before it reaches the hot end. This results in under extrusion and extruder skipping because it needs a lot more force to push the filament through the hot end. Also, when changing filament, I had to take the extruder apart because due to the bulging of the filament, the filament got stuck in the lever of the extruder. So for now, I'm stuck with using the stock but very noisy fan until I find a proper "silent" replacement...

Ottimo prodotto,preso per sostituire una ventola simile su una stampante 3d ma fastidiosa per il rumore. Questa è silenziosissima.

Quality fan, as described. Replaced the drive cooling fan in my Ender 3, Original fan was way to loud... This fan you cant even hear at full speed, and it pushes more air the the original fan as well!

Ich habe mir den Noctua-Lüfter für mein PC-Gehäuse gekauft, um die Kühlung zu verbessern – und ich bin absolut begeistert. Die Verarbeitungsqualität ist, wie man es von Noctua kennt, erstklassig. Alles wirkt durchdacht und hochwertig, vom Lüfterrahmen bis zu den vibrationsdämpfenden Gummiecken. Was mich besonders überzeugt hat, ist die extrem leise Laufleistung – selbst unter Last bleibt der Lüfter kaum hörbar. Gleichzeitig sorgt er für eine hervorragende Luftzirkulation und hat die Temperaturen in meinem System deutlich gesenkt. Auch die mitgelieferten Zubehörteile wie Y-Kabel, Low-Noise-Adapter und hochwertige Schrauben zeigen, dass Noctua an alles gedacht hat. Fazit: Wer Wert auf Qualität, Laufruhe und Effizienz legt, kommt an Noctua kaum vorbei. Der Preis ist zwar etwas höher, aber absolut gerechtfertigt. Klare Kaufempfehlung für alle, die ihren PC aufrüsten oder optimieren möchten!
