"the NF-A12x25 manages to outperform the Gentle Typhoon AP-15 by only a hairline"

"Of all the fans that could be considered looking similar to the NF-A12x25, the Nidec Gentle Typhoon proved to be the hardest competition, but we’re confident that our design is slightly superior. In our tests on a typical 2 inch all-in-one water cooler at 200W heatload with both fans adjusted to the same noise level, the NF-A12x25 with the supplied radiator gasket provided about 0.3 to 0.6°C lower temperatures than the Nidec depending on the speed settings. At the same time, our premium grade SSO2 bearing runs virtually inaudibly whereas the Nidec’s ball bearing produces an unpleasant tone that becomes clearly audible at lower fan speeds. Last but not least, unlike the NF-A12x25 with its integrated silicone pads and gasket, the Nidec doesn’t have an anti-vibration mounting and thus transmits vibrations and resonances to the radiator and case. All things considered, we’re confident that the NF-A12x25 is the best 120mm fan currently available."
