Buy AVC 9025 12V 0.56A 9CM/Cm 4-Wire Max Airflow Rate Chassis Fan DS09225B12U Online today in the Electrical Department Vialetter.
Application: Computer Case
Compatible CPU: yes
Fan Life: 40000 hrs
Heatsink Material: Plastic
Brand: Taiwan Qihong AVC manufacturer: Taiwan Qihong Technology Co., Ltd. (Asia Vital Components Co.,Ltd)
size:92*92*25mm (I .e. 90*90*25mm)
interface: motherboard 4-pin
rotational speed:4200 RPM
description: The fan is equipped with PWM temperature control function, and the rotating speed is very low at normal room temperature. When the temperature inside the box or around the CPU rises, it will gradually accelerate, which not only plays a role in heat dissipation, but also does not produce too much noise.

AVC fan bearing identification:
yellow label: double Ball Bearings B = 2 Ball Bearings ( A double ball bearing)green color label: Oil Seal bearing S = Sleeve ( oil Seal)blue label: one Ball one Sleeve bearing T = 1 Ball 1 Sleeve ( one ball one sleeve + Oil Seal)
purple red color label: Hydro bearing or magnetic suspension bearing R = Hydraulic ( hydraulic)
double Ball Bearing (2 Ball Bearing) is a relatively high-grade Bearing, which adopts the form of rolling resistance and two Ball bearings. There are several tiny steel balls around the axis in the Bearing. When the fan sheet or axis rotates, the steel ball rotates immediately. Because they are all balls, the friction force is small and there is no problem of oil leakage. The advantage of double ball bearing is that the service life is too long, about 50000-100000 hours; The ageing resistance is good, and it is suitable for fans with high v speed. The disadvantage of double ball bearings is that the manufacturing cost is high and the noise is the largest at the same speed level. Double Ball wind bearing and hydro bearing have good sealing property, especially double ball bearing. The double ball bearing is embedded in the fan, and the rotating part does not have direct contact with the outside world. In the sealed environment, the working environment of the bearing is relatively stable.
Features maintenance-free double ball bearing, long service life, sufficient heat dissipation air volume and wind pressure
