Spire Air Force 120 LED (SP12025N7L4-B-PWM)
The Spire Air Force 120 LED (SP12025N7L4-B-PWM) is quite an interesting product, although there's nothing special about it in terms of packaging. The fan is shipped in a cardboard box covered with exhaustive information about its features.
The fan comes without any accessories save for a sleeved 4-pin cable.
Manufactured in China, it has a 5-year warranty and a recommended price of $15.
The Spire Air Force 120 LED looks quite attractive. The translucent frame and impeller contrast with the blue silicone corners.
The fan is rather light (133 grams) and elegant. The impeller is 110 mm in diameter whereas the motor is rather small: only 41 mm in diameter.
The interior of the frame is flat. The company’s website address can be read from the outer surface of the frame.
The saber-shaped blades expand towards the ends and have a sharp front edge. Thanks to PWM-based regulation, the Spire Air Force 120 LED can rotate at 600 to 1500 RPM, producing an air flow of 62.4 CFM and a static pressure of 1.76 mm of water. Its noise varies from 10 to 22 dBA.
The silicone corner inserts are yet another special feature of this model:
Serving the same purpose as silicone pins, they are meant to reduce vibrations and noise. The inserts can be easily removed and put back in place.
The fan runs on a nano bearing which seems to be some kind of a fluid dynamic bearing. We can only learn its service life from its specs: 70,000 hours or almost 8 years of continuous operation.
At the maximum speed the Spire Air Force 120 LED can consume 1.44 watts at 0.18 amperes. The startup voltage is not specified.
There are four blue LEDs in the corners of the frame. The highlighting isn’t bright and looks very cute.
The cable is 300 mm long.
