New original Delta 7CM 7015 AFB0712VHB 4-wire PWM automatic temperature control CPU cooling fan

Brand: Delta
Model: AFB0712VHB
Bearing: Double Ball (2 Ball Bearing with Special Designed IC Inside)
Mean time between failures (MTTF): 180, 000 hours
Voltage: 12V
Current: 0.55A
Speed: 5200 rpm
Noise: 44dBA
Air volume: 45CFM
Cable length: 20 cm
Interface: 4-wire
PWM Weight: 47 grams With thermistor automatic temperature control, it also supports motherboard PWM intelligent temperature control, which means that only connecting the positive and negative 2-wire fan to the fan will also automatically control the temperature and speed. If it is connected to the 4P interface of the motherboard, the fan is also equipped with Two speed control modes. The motherboard 4P interface, compatible with 3P, can also automatically adjust the speed according to the temperature of the air blowing through the thermistor when connected to 3P, which is very suitable for replacing the CPU cooling fan with a cable length of 20cm. The current is 0.13A at room temperature. The speed is 3300 rpm, and the short-circuit thermistor current is 0.45A., The speed is 6400 rpm, as the temperature of the chassis is higher, the fan will turn faster and faster from
3300. When it reaches a certain temperature, it will be at full speed at 6400 rpm. This is the increase in air volume, better heat dissipation, and greater noise.
Note: The temperature control of this fan is very sensitive. It will run at full speed above 40° and run at 6600 rpm. It is suitable for those who like high speed. If you need to keep high speed, you can remove the temperature control capacitor or short-circuit it, and he can keep it. Run at maximum speed.
