Good product; beware of second fan purchase
Pros: Great performance and quiet.
Cons: You cannot buy a second *identical* fan matching the included fan for a dual fan configuration.
Overall Review: Wonderful cooler. However, if you decide to purchase a second identical fan (for which the mounting clips are provided), the *retail* version of the fan that is included with this cooler is *not* the same fan. I have verified this with Noctua support after noticing a difference in fan speeds. The NF-A15 PWM fan that is included with the cooler runs at a max of 1500 RPM, while the NF-A15 PWM identical colored fan that is purchased separately (called Retail by Noctua) runs at a max of 1200 RPM. Be aware of this if you are purchasing an additional fan. I have suggested to Noctua that they change to model number to reflects this because it is misleading to the consumer since the model numbers match, therefore the fans should be identical. They suggested that I buy the black "chromax.swap" version of the fan, which runs at the higher speed, but doesn't match in color, which I didn't want.
Good fan; not the same fan as that included with Noctua coolers
Pros: Quiet and moves the air well.
Cons: Not the same as fans included with coolers despite same model number.
Overall Review: Be aware that this fan, the Noctua NF-A15 PWM, is not the same as the Noctua NF-A15 PWM included with Noctua coolers. This fan (called the retail version by Noctua) runs at 1200 RPM and is *slower* than the Noctua NF-A15 PWM included with coolers, which run at 1500 RPM. I have verified this with Noctua, who suggested I use a black chromax.swap fan, which doesn't match the color of the included version on my cooler. Having the same model number is a bit misleading.
