Noctua NF-A4x10 FLX, Premium Quiet Fan, 3-Pin (40x10mm, Brown)

Super produit pour ma CR10-S un peu chère mais ça vaut vraiment le coup !

Quite simply, I will always buy this brand, they are built second to none and you cannot beat the noise levels! Getting the FLEX kit only reinforced the level of quality that goes into the product, when you see the number of applications one kit can have.

This fan worked great as replacement for the noisy hot end cooling fan on my i3 Mega. Super quiet and made of great quality materials. Even came with decent instructions and extra connectors.

I was working on an ACER desktop. BIOS had SmartFan application. CPU was running at 94 degrees Celcius. Replaced the heat sink grease. Still hot CPU. Turned SmartFan off in BIOS. SmartFan no longer reduced the 5volt CPU fan speed, but it did turn off the CPU fan after some minutes. The CPU fan connector is 5volts, the case fan connector is 12volt. The solution - this 12volt fan mounted on the CPU heat sink and powered by the motherboard case fan connector. Case fan is not controlled by SmartFan app. With this 12volt fan the CPU is running at 47 degrees Celsius; same programs running in each test. And the fan is so quiet, you do not know it is running constantly.

Very quiet. Nice

Bought an Asus Prime Z270a mobo. Bought a Corsair M500 M.2 drive. The Corsair is a nifty device, but the controller runs awfully hot. At first, I peeled off the copper heatsink label that covers the Corsair, and replaced it with some several tiny copper heatsinks. That helped, but without some airflow, the heat would just linger rather than fully dissipating. Asus makes available 3D printing plans for a tiny fan mount to go over the m.2 slot. I dont have a 3D printer, so I just ordered one from a maker site. Mounted this little fan on it, and whoosh - heat be gone. That its silent is just an added plus.

Awesomely quiet fan. Replaced some noisy buggers in a switch. The switch now runs dead silent.

Muy buena presentacion y con muchos accesorios, pero el objetivo de la compra era disminuir el nivel de ruido y este es mucho mayor del esperado. Hace tanto ruido como el ventilador que tenia mi impresora de serie.

Very happy with the product

Noctua fans have always looked pretty ugly to me but their performance is downright beautiful. These are silent unless you have your ear inches from it and the airflow is solid. I am using these in my 24v Ender 3 Pro with a buck driver to drop the voltage down to 12v. They dont quite move as much air as the 24v ball bearing upgrade fans but they produce an easy 1/4 of the audible sound and I fully trust that they will last for years and that is important. I run these on my printer in the stock hotend housing and a Micro Swiss hotend and after a PID autotune the temps are wonderfully stable and reliable. However for my application I had to replace the stock fan screws with slightly longer ones so they would reach the mounts solidly. They also work great as a replacement for the stock motherboard fan with no modification other than a 12v buck driver. I power my motherboard fan off the hotend fan header as opposed to the original design that powered it off the parts cooling fan so it is on whenever the hotened is heated because I noticed it never ran while I was printing ABS due to the parts fan being off.
