The Adda AD1212MS-A71GL is a 120mm Low Voltage Axial Fan which is an oil impregnanted sleeve bearing unit. It requires 4.08 Watt of power and operates at up to 2,050 rpm for a 80.5 CFM rated airflow capacity. The company rate the fan as producing a maximum output of 38dB, however under normal circumstances it should generate significantly less.
The internal design is very clean with massive ‘L-Shaped' heatsinks spreading across the full diameter of the PCB. These sinks are directly under the airflow of the fan and will ensure maximum cooling efficiency.
This is an Active PFC design which offers full protection for OVP/UVP/OCP/OPP/OTP and SCP. The single rail design in this particular unit delivers up to 48A on the 12V. The Hybrid Heatsink is a switching mofset design and the capacitors throughout are all Japanese made, high quality units. The VRM control transfers to 5V and 3.3V.
The design also places the IC close to the transformers which are required to create the high efficiency ratings. It complies with the latest Intel ATC 12V V2.3 standard and there is a double layer EMI filter to help reduce noise.
The cabling is fully sleeved inside the unit and is rubber protected to ensure no wires will get damaged caused by abrasion against the metal chassis.
