NZXT FZ-140 and FZ-140 LED
As opposed to the previous pair, the FZ-140 and FZ-140 LED are only accompanied by a power adapter and mounting screws.
The country of origin is China; the warranty is 2 years long. The model without highlighting costs $16 while the highlighted model is $21.
Despite the same form-factor of 140x140x25 mm as the previous pair, these are completely different products both in the shape of their 130mm impellers and in the design of their frames.
The 13 flat blades get narrower at the base and have thick ends. The interior of the frame is smooth and lacks any ribs. Take note of the cutouts at the edge of the frame where the air goes in and out.
The manufacturer doesn’t reveal their purpose, but we can suppose that they serve to reduce the noise somehow. Unlike the unhighlighted version, the models with orange and green highlighting have a translucent impeller but their specs are perfectly the same: 1000 RPM, an unexpectedly high air flow (for the specified speed) of 83.6 CFM, a static pressure of 0.81 of water, and a noise level of 24.5 dBA.
The motor is only 40 millimeters in diameter. Its sticker tells you the type of the bearing, the product's model name and electrical specs.
The improved sleeve bearing is expected to serve for 40,000 hours or 4.6 years continuously. The peak power consumption of the unhighlighted version is 1.8 watts. Its highlighted cousin needs up to 2.65 watts. The 3-wire sleeved cable is 500 mm long.
