Dear friend, You may compared our prices with other products. But we never only compare our price with other products. Our features: 1. ライン: High conductivity industrial-grade materials. 2. フレーム: Industrial environmental protection plastics,Extrusion molding process 3. Blade: Unique aerodynamic design, independent research and development(crab legs). 4. ベアリング: Hydraulic bearing, 長寿命, low wear, high temperature resistant, 低ノイズ. 5. Shockproof silicone cover: Environmental protection silicone material, shockproof, reduce noise. Air pressure and air volume comprehensive fan
Flying crab has the fastest speed in all crabs, because it has special shape hind legs.
We adopted the crab legs for the fan design. Not only appearance fashion and unique,
but also embodies the high performance of the fan. It is efficiently increased the air flow
by 15% and a 5% reduction in noise in the same speed.

How to choose your fan?
In fact, the selection of a suitable fan is not difficult, as long as a good judge of your own needs and
product specifications, then you can choose them from a range of budgets. Usually we choose are
basically two types of fans, wind pressure and wind volume. Characterized by a large wind pressure
is mainly suitable for use in fan with air filter position chassis panels, 等, and the wind volume fans
suitable for the top, rear and other places of the chassis.
Different types of fan blades due to the different types, size and angle, when installed in different
positions will have different effects.
The front panel fan typically requires a large pressure type of fan can blow through the front of the
シャーシ, which will inject a steady stream of cold air inside the chassis.
The inclination angle of the fan blades and blade curvature of the two factors that influence the
value of a fan pressure largely are. Blade curvature and inclination angle larger the value, at the
same rotational speed, the greater the pressure supplied. This type of fans is particularly suitable
for use in the front of the chassis, as the intake fan to use.
In the back of the chassis, usually equip with a heat exhaust fan, so wind volume more important
than the wind pressure. At the same time, the heat inside the chassis can be more quickly discharged
to the outside of the chassis is the most important.
Most wind volume types of fan have characteristics of more quantity blades and more moderate
inclination angle of the blades, this design is very suitable for use in top and rear of the chassis.
If you are not very pursuit for thermal performance, just want to mute the computer stable job,
then you can choose biased silent type of fans. Of course, if you do not want to replace the fan,
you can also choose a fan controller to reduce the fan speed down.
