Box, Contents & Bundle
Arctic sent me the 3-fan package. Since this is a server-oriented product, don’t expect a fancy box. It’s just plain cardboard with a sticker showing the fan model and the basic specs.
The fan has five large blades to produce more airflow and static pressure. The larger the fan’s blades, the more air they push. Their angle of attack also plays a role in this.
There are no rubber pads on the fan’s corners since vibrations will be increased at full speed whether these pads are present or not. The fan’s width is also increased to accommodate the large motor, and the fan’s blades can also be larger.
The fan uses a dual-ball bearing, which is the standard in server and industrial applications since this type of bearing can withstand high operating temperatures.
