FeatureRound Frame w/150mm width: Tailor-made for use on today's high-end CPU coolers: While its 150mm width matches those of most high-end heatsinks, its 140mm height doesn't make it extend on top and thus ensures best case compatibility. Standard 120mm mounting holes (105mm spacing) also make it an ideal performance upgrade for 120mm case or CPU fans.
AAO Frame: Integrated anti-vibration pads, Stepped Inlet Design, Inner Surface Microstructures. All further refine the fan's performance/noise efficiency.
Flow Acceleration Channels: Leads to better efficiency and lower vortex noise.
SSO2 Bearing: Provides even better stabilisation, precision and durability
Metal bearing shell: a CNC milled bearing shell made entirely from brass provides the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability

Noctua NF-A15 PWM

review by cyclops

It's been a long time coming but here is what everyone has been waiting for. Noctua's brand new A series fans. I'll be reviewing all three 140mm models over the next few days. Today though, I'm going over The NF-A15 PWM.

I could talk about stepped inlets, dimpled inner frame, brand new blade design with flow acceleration channels, SSO2 bearing, etc all day long, but that's not really my style. What matters to me is raw performance and this fan delivers in spades.

In short, The NF-A15 PWM beats every single fan I've tested to date in every single configuration when comparing noise to temperature ratings. What it means is that the A15 is the most efficient 140mm fan I've tested so far. It is quiet in push mode and dead silent when you use the included low noise adaptor (LNA). When I attached the LNA, I was really surprised by the amount of air it was moving considering its almost inaudible operation on an open test bench.

It just goes to show that all those new technologies with their fancy acronyms do actually work when incorporated correctly and as such, Noctua deserves all the praise they can get for this truly innovative product.

Now, this wouldn't be a complete review if I didn't point out some of the negative and/or controversial aspects of this fan.

The color scheme, for example, is a love or hate thing for most people. It actually doesn't bother me, in fact. it has grown on me since I've been using Noctua fans for quite a while. They are Noctua's distinctive colors, kind of like a national flag and whether you like it or not, they're here to stay.

The other less concerning matter is the price. At 25 bucks a pop it's not exactly cheap, but pretty much all Noctua fans have been carrying the exact same price tag and people still buy them because you do get what you pay for. Consider all the goodies you get with this fan. Rubber grommets for extra vibration dampening, extended fan cable, splitter (Y) cable, low noise adaptor, and to top it all off, a jaw dropping 6 year warranty. It's actually a pretty good deal.

Now I have to address the elephant in the room. This fan gets quite loud when you use it in a pull configuration (At least on my setup) and I found that a bit disappointing. The noise went up by a fair bit than when It was running in push and it started generating that good ol' annoying whining noise. Still, I don't blame it that much since pretty much every other fan I've tested exhibit similar symptoms. It's not as bad when you slap the adaptor on, in fact, it improves noise to temperature efficiency so you do have that option.

Overall, a very impressive product that comes highly recommended from me.
