GlacialTech PWM Fan (GT12025-LBD0A)
Although an entry-level product, the GlacialTech PWM Fan (GT12025-LBD0A) has some simple cardboard packaging.
Product specs are listed on a sticker on the back of the box. The fan is only shipped with four self-tapping screws, which isn’t surprising considering its price of only $3. The GlacialTech PWM Fan lacks any visual pretense. It is an ordinary plastic 120mm fan with a black frame and a black impeller. It weighs 115 g.
The impeller is 112 mm in diameter; the motor is 40 mm in diameter. The photo shows the inferior quality of the impeller that has notches on the outer edge. The junction between the blades and the motor is finished sloppily.
Well, we could hardly expect anything better from a fan that costs so little. But unlike the four previous models, the GlacialTech PWM Fan features PWM-based regulation, so the speed of the fan can vary from 700 to 1400 RPM. The air flow, static pressure and noise are specified for the maximum speed: 62.3 CFM, 1.8 mm of water, 29.6 dBA, respectively.
The service life of the dual ball bearing is declared to be 50,000 hours or over 5.5 years of continuous operation. The sticker on the fan is quite informative:
The GlacialTech PWM Fan should consume no more than 1.8 watts at 0.15 amperes. The 4-pin cable is only 295 mm long.
