NoctuaNF-A14x25 G2 PWM Sx2-PP, Dual Fan Set for Push-Pull and Side-by-Side Applications (Brown)

Quiet, premium, and come with plenty of accessories. The quality and performance of these are unparalleled. I love how they have offset max rpm to avoid a beat frequency.

Let's be real, if you're even thinking about spending $40 a fan, you've got your priorities a little mixed up. But these are beautiful (if you like Noctua brown...), and quiet, and well-regulated for speed (down to 300 rpm). And knowing Noctua, they are probably going to outlast every other component in my case.There's a note included about proper "load relief" for mounting. When you install in a push configuration, you need to use the included gasket or special rubber corners with raised "load relief rings" between the fan and the radiator. There is also a special mention to not overtorque the mounting screws.

You pay the price but you get the performance. 5 stars. Very quiet, very powerful, nice. Instructions on installations on which grommets is spotty but still give it 5.

I absolutely love the look, quality, sound and speed of noctua fans. Excellent choice for a NAS build that's on 24/7. Gonna get a Noctua CPU cooler next

The gimmick here is that offsetting fan speeds prevents resonance and therefore annoying fan noise. I'm not sure how big of a problem that really is, but you might as well save on packaging if you need multiple fans. The main complaint I have is with the silicone screw alternatives: on my case, they stick out too far from the fan, preventing me from closing the front panel without popping a fan out. So, basic screws for me.These replaced a bunch of iPPC 3000s and they work just as well for my build while being way quieter. When Noctua tells you that you don't need their "industrial" line, they mean it.

Silence is golden is what these fans are. Put these on a 280 AIO inside a SFF case and with all the mesh around the case the 2 Noctua A14 G2's are cooling and bringing in fresh air through out the case while being so quiet. Seriously I've tried all the other good fans but these are the best fan bearings in the business. No weird noises in any of the rpm ranges, a lot of fans out there have this problem. 10 years of waiting is worth it!

I replaced my Lian Li AL140v2 fans with the Noctua A14x25 G2 fans, and the difference is significant. Not only are the Noctua fans quieter, they also blow far more air into my case as front intakes. I highly recommend them because you're not just buying for the fans, you also buy their top tier customer support.

All good! When you need one, go for one of the best!
