CPU Cooler Fan For DS09225B12U DC 12V 0.56A 90*90*25mm 4Pin

Model: DS09225B12U

Size: 90*90*25mm
Voltage: 12V

Current: 0.56A

Connector: Motherboard 4-pin

CORD LENGTH: 15CM

Fan rotation: Runs counterclockwise from the direction of the fan blades

Temperature: -20 degrees Celsius to +70 degrees CelsiusStorage temperature: -40 degrees Celsius to +80 degrees Celsius

Power supply range: plus or minus 15% of rated power supply

Insulation resistance: more than 500 megaohms

Working life: 100,000 hours when the ambient temperature is 25 degrees

Double ball bearings (2 Ball Bearing) are relatively high-grade bearings, using the form of rolling friction, using two ball bearings, there are several tiny steel balls around the shaft, when the fan or shaft rotates, the steel balls rotate. Because they are all spheres, there is less friction and there is no problem of oil leakage. The advantage of double ball bearings is that the life is very long, about 50000-100000 hours; Good anti-aging performance, suitable for fans with higher V speed. The disadvantages of double ball bearings are high manufacturing costs and are the most noisy at the same speed level. Double ball air bearings and hydraulic bearings have better closure, especially double ball bearings. The double ball bearings are embedded in the fan entirely, and the rotating part is not in direct contact with the outside world. In a sealed environment, the working environment of the bearing is relatively stable.

Features maintenance-free double ball bearings, long service life, sufficient heat dissipation air volume and air pressure
