Silverstone Air Penetrator 120i PRO

Visual inspection

The Air Penetrator 120i PRO is based on the original Silverstone Air Penetrator fan, which was first released in 2010. The main purpose of the Air Penetrator 120i PRO is to deliver optimal airflow inside the chassis. The fan does that by focusing its airflow into a channel shape at the back.
The design of the Air Penetrator 120i PRO is simple, with no RGB LEDs to be seen, or any colors integrated into its plastic frame. The main design elements are found within the impeller assembly and at the back of the fan.
The fan has the standard dimensions: 120 x 120 x 25 mm and a maximum speed of 2000RPM.

 

The Air Penetrator 120i PRO uses a total of 9 impellers. However, there are in fact three sets of three impellers. Each set has a different shape than the others, using different shapes for the impellers is done to reduce the overall noise of the fan.

 

The gap between the tip of the impellers and the inner side of the frame is approximately 3mm. A small gap means less air and static pressure leakage occurring especially if the fan is installed on a heatsink or radiator.

 

The Air Penetrator 120i PRO has a standard dual ball bearing system. This system is known for its reliability and low noise operation. The fan and bearing system are rated for 70,000 hours.

 

The frame unfortunately has no padding at all. Fortunately, a set of four rubber mounts is included in the package with the fan. However, this does not solve the issue of installing the fan on a heatsink or radiator.

 

The back of the fan features a circular line pattern which is designed to focus the airflow of the fan into a channel. This makes the Air Penetrator 120i PRO useful for directing the airflow to certain sections of the system, such as the graphics card.

 

The back of the fan hub is covered by a simple label which contains the model number of the fan, the manufacturer’s logo and the operating voltage.

 

The Air Penetrator 120i PRO has a single cable which is all black. The cable itself is flexible and of high quality, however sleeving would have helped in protecting the wires.
For powering the fan, a single 4 Pin connector is used.
