for Reference only:
- DC Fans usually
come in 5V, 12V, 24V or 48V. Computer fans, PC systems fans, CPU
cooling fans, Chipset fans, hard drive coolers usually use 12V DC fans or
5V DC fans.
- Ball Bearings
& Sleeve Bearings: Ball Bearings
are better quality bearing option for fans. Ball Bearing Fans last longer but have higher
temperature ratings and it is noisier. Manufacturers also make Double
Ball Bearing Fans to extend their life circle or Single Ball
Bearing Fans to cut the costs. Sleeve Bearing fans are a
less expensive and less robust alternative to Ball Bearing fans.
- Ceramic
Bearing: Ceramic
bearings are rotary bearings constructed of ceramic. Ceramic hybrid
bearings, the most common type of ceramic bearing, are constructed of
steel inner and outer rings with ceramic balls in place of steel. These
bearings have several advantages over all steel bearings, such as higher
speed and acceleration capability, increased stiffness, higher accuracy,
lower friction and heat generation, reduced lubrication requirements,
low thermal expansion, and extended operation life. Bearings containing
all ceramic balls are also nonconductive and are commonly used in
electric motor applications.
Nanometer
Ceramic Bearing ( So called Ceramic Bearing, NC Bearing,
NCBearing, or NCB ) has longer Life Span ( Double Hours of
Sleeve and Ball Bearing ), lower noise, better Durability, Anti-Shock/
Anti-Vibration, Water Proof, Resistant to Oxidation and Chemicals.
Compare NCB to Steel and Copper on Hardness (HV) and Extension
Coefficient (ETC 10-6/˚C):
NCB - 1340 (HV), 3.0~8.3 (ETC 10-6/˚C),
Steel - 560 (HV), 11.2~14.3 (ETC 10-6/˚C),
Copper - 240 (HV),
20 (ETC 10-6/˚C).

- Hydrodynamic Bearing (
HDX Hydro Dynamic Technology ): hydrodynamic bearings are fluid film
bearings that rely on a film of oil or air to create a clearance between
the moving and stationary elements.
- VAPO
Bearing & MagLev Design:
Vapo bearings are made
of a material specially treated for wear-resistance and
impact-resistance. When used in conjunction with the MagLev, it creates
a spring function, which helps the fan motor to bear impact. MagLev
design helps the rotor to rotate evenly in a fixed orbit within
the orbit center without any friction with the bearing bore. No
vibration occurred. This new system eliminates the use of oil rings and
washers, thus leaving space for the release of gas occurring during
normal operation. No more clogging problems. Vapo bearing is named after
this character.
-
CFM: Cubic Feet per Minute (airflow).
- DC Fan Power
Connector: Computer fans usually get its power from switching power
supply with Molex 4-pin power connector or with 3-pin PC Mother Board
connector to be connected to the system's main board. Sometimes the DC
Fans also come with different types of 3-pin, 2-pin connectors or just
with bare wires.
-
Brushless DC fans: Most computers use brushless DC motors
since they are clean (no brushes to create carbon dust or to wear out)
and are now smaller and less expensive.
- UV (Ultraviolet)
- Part of the electromagnetic spectrum in which the
longest wavelength is just below the visible spectrum, extending from
approximately 4nm to approximately 400nm.
