Enermax T.B.SILENCE (UCTB12A)
The Enermax T.B.SILENCE is packaged like the above-discussed Cooler Master.
You can see its model name and icons denoting the fan’s key features on the front side of the paper insert. Detailed specs are listed on the back.
The fan comes together with a PATA power adapter, screws and a piece of dual-sided scotch for the speed controller.
The Enermax T.B.SILENCE is manufactured in China and costs $14. Its warranty period is 1 year.
The fan looks really beautiful with its perforated black glossy frame and 9-blade impeller with matte plump blades.
It is the lightest fan in this review at only 102 grams.
Designed in Enermax’s exclusive Batwing style, the impeller is 110 mm in diameter. The motor is 41 mm. The interior of the frame is perforated with the letters “Enermax”. Besides aesthetics, this solution helps improve the air flow by allowing the air to come in through the side holes.
The rotation speed of the Enermax T.B.SILENCE can be regulated manually from 800 to 1500 RPM to change its air flow from 37.6 to 71.3 CFM and static pressure from 0.72 to 1.68 mm of water. The specified noise level is 10 dBA (obviously, at the minimum speed).
There’s a lot of useful information on the motor’s sticker.
Besides the electrical specs (12 V, 0.3 A, 3.6 W), we can note the bearing type. The Twister is a patented design Enermax has been using for over 3 years. It combines the long service life of ball bearings (100,000 hours according to the specs) with the low noise level of sleeve bearings.
The startup voltage is not specified but we will measure it ourselves. The cable is long at 490 mm.
