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

Compared to other fans in it's class it's noise performance is leading with delivering excellent airflow to facilitate the best possible cooling in your rig. As you expect as the fans are able to deliver excellent air flow at lower speed Vs the competition it naturally is quiter at the high noctua quality you expect, of course this comes at a premium but well worth it.

Works perfectly. Noctua are my go-to for anything air cooling. The amount of air that they can push is amazing, it's like the power of a proper room fan. Moving to these from my previous arctic 212 120mm fans, I've seen ~10c improvements, this is from a 5 fan 120mm setup to a noctua 5 fan setup, with 4 140mm fans (these ones) and a nf-a12x25 G2 at the rear. Noctua aren't cheap, but you definitely get what you pay for.

Do you hear that? No? That's coz its a noctua fan! Runs dead quiet and my previous issue of vibrations is remedied by the anti vibration 'screw' and pads. To be honest the offset speeds isn't something I can compare, but if the sync up sound has bothered you before, I'm sure they're good. In my opinion they are the absolute best fans you can get, but obviously you pay a premium. They're not the best value, be quiet and fractal are better. You're probably paying for a few decibels better, but if you want absolute best, you pay that premium.

Noctua fans really are the best. Quiet, reliable, trusted.

Quiet and powerful. I already owned 3 of the old type 140mm fans. Needed 2 extra for my new case, so bought these to use as intake fans.

Excellent set of fans, highly recommended for performance and silence

Swapped my case to Antec Flux and fit 4x NF-A14x25 G2 PWM Sx2-PP at the same time, 3x at the front and 1 in the rear, used 1 NF-A14x25 for PSU shroud intake, really impressed with how you can't hear these fans under 800 RPM, even at 400 RPM the amount of air they move is impressive, they can be heard once you start increasing the RPM however with the amount of air they move I don't have to have them above 600 RPM. As in Noctua fashion you get a very nice unboxing experience and they come with all the usual accessories you'd expect, one thing to note is by default the fans ship with the radiator rubber gasket preinstalled unlike previous Noctua fans that come with the 4x corners preinstalled so you'll have to swap them over. Expensive when compared to other fans on the market however I'm more than happy with my purchase.

Very fast delivery, good price
