1. "Waterproof Cooling Fan" Air Flow air volume - is calculated in units of [CFM] (Cubic Feet per Minute cubic feet / minute): The higher the number, the stronger the wind representative.
2. "Waterproof Cooling Fan" 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. "Waterproof Cooling Fan" Fan Speed fan revolutions - computing unit for [RPM] (Rotation Per Minute number of rotations / min): RPM fan vibration, wind noise and operational noise are closely related.
