220V AC Cooling Fan specifications and common nouns Profile

1. "220V AC Cooling Fan" Air Flow Air Volume - Units for [CFM] (Cubic Feet per Minute cubic feet / minute): The higher the number, the stronger the wind representatives.
2. Air Pressure Pressure - The unit is [mm-H2O] (physical gas unit, mm water column): The higher the number the more pressure on behalf of Jin.
3. Bearing bearing technology - including seals (Sleeve), a single bead type (One Ball), lacoste formula (Dual Ball), NFB (Nanoflux), patented magnetic levitation (Twister) and MagLev vaporization Maglev (Vapo).
4. "220V AC Cooling Fan" Fan Speed fan revolutions - The unit is [RPM] (Rotation Per Minute number of rotations / min): RPM fan vibration, wind noise and operational noise are closely related.
5. Connector plug wires - common large and small 4-pin 3-pin and 4-pin small. Small 3-pin fan circuit board can be used with the IC package and the motherboard socket or optional speed control panel with tachometer function, a small 4-pin fan on the board according to the IC package and the motherboard socket in addition to a speed function, it can also provide a PWM speed control function.
6. "220V AC Cooling Fan" Voltage Voltage - [V] is calculated in units of volts, standard computer fan voltage DC12V, may depend on the factory specifications and the need for reduced home with mute 7V or 5V. Fan speed will slow down, bearing sound, wind noise and other noise decreases, the result is the air volume and pressure will diminish.
7. Current Current - [A] is calculated in units of ampere, the larger the number, the higher the normal A representative number of revolutions of the fan page.
8. Watt Circuit Power - The unit is [W] Watt, the higher the number of revolutions of the blades on behalf of watts under normal circumstances would be greater.
9. PWM electronic pulse frequency modulation - full name [Pulse Width Modulation], mostly used in the CPU cooling fan (with a small 4-pin socket) on. In a nutshell is the temperature sensing components (Sensor IC) computer motherboard temperature data transfer to the motherboard Signal Generator (signal conversion) electronic components, generating a pulse signal together with the cooling fan speed control circuit board, IC electronic components, default program scheme according to the fan manufacturers, through conversion (trimming fan voltage) to control the fan RPM, achieving low-temperature and high-temperature high to low turn temperature effects.
