![]() ![]() There is a covered port with a LED label. The top header is the 4-pin port labeled FAN. There are two headers built right into the frame of the fan. These fans are using a modular design to simplify cable management but use a proprietary design. The above picture shows one corner of this fan in particular. The frame is quite sturdy and has line patterns all around. There are cut-to-size anti-vibration pads on all mounting corners. When similar pattern is applied on fan blades, results in passively altered flow to favorably affect the pressure gradient along the fan blades which improves the overall airflow performance and noise level.” Here is what SilverStone is saying about this design element, “Inspired by the hydrodynamic properties of shark skin which acts as drag-reducing mechanism to improve their aerodynamic motion. ![]() ![]() The above picture is showing a close-up view of the fan blades. All 4 borders in the center of frame have a thin line style layout compared to the mounting arms. There is a SilverStone branding in the center. However, there is a distinctive design element over the blades. We can see that a complete assembly is in a black color. These blades are made of Polycarbonate material. However, basic geometry and design are the same in both sizes. This fan has 7 blades, unlike the 120mm version which has 9 blades. Reliable and durable fluid dynamic bearing.Modular cable design simplifies connection and management of cables.Unique three phases, six-pole design which allows for smoother, quieter operation compared to most single-phase, four-pole design.Wide 0~2,200 RPM speed range via PWM control.Distinctive “Shark Force” fan blade design for lower noise and higher performance.Let’s take a closer look at the fan starting with the salient features: There are 4x self-tapping screws provided with these fans. The warranty period varies from region to region. SilverStone is offering a 1-year limited warranty in the North American region. SilverStone has provided the following in the box: The maximum rated speed on these fans is 2200 RPM generating a massive airflow of 120 CFM using 4mmH₂O static pressure. Salient specifications are listed over here. Shark Force 140 is printed over here showing the model of this unit. Printing is done right over this cardboard packing box. Price: USD 27.36įans are shipped inside a brown color cardboard box. These fans feature a daisy-chain cabling system which simplifies cable management. These are performance enhanced 140mm PWM fans having a maximum airflow rating of 140CFM and air pressure rating of 4mmH₂O. This is a dedicated review of these fans. SilverStone has joined our coming-up comparative performance of 140mm fans on ALPHACOOL SuperNova 1260mm radiator and sent us 20x SF140 fans for this purpose. This time we are taking a look at Shark Force SF140 fans. These are available in 120mm and 140mm sizes. SilverStone recently released their next generation, high-performance edition fans named Shark Force (SF). ![]()
