CPF04 vs SST-CPF04-USA Comparison
Connector compatibility
Both hubs provide one input and eight output connectors for PWM fans. The SilverStone CPF04 model lists its features without specifying 3-pin support details. The SilverStone SST-CPF04-USA model explicitly states it includes PWM 4-pin headers. It also notes that while it is compatible with 3-pin cables, speed control is unavailable for those fans. Attached 3-pin fans will run at maximum RPM. This clear warning helps you avoid confusion if you plan to use older 3-pin fans with the SST-CPF04-USA.
Mounting options
The SilverStone SST-CPF04-USA model includes 3M adhesive tape to apply the hub anywhere within your case. This feature is listed in its features section. The SilverStone CPF04 model data does not mention any included adhesive or mounting tape. You may need to source separate mounting solutions for the CPF04. The included adhesive on the SST-CPF04-USA simplifies installation by allowing you to stick it to a flat surface inside the chassis without needing additional screws or brackets.
Physical dimensions
Both products share identical physical dimensions. The SilverStone CPF04 measures 0.75 inches in width, 1.57 inches in height, and 2.13 inches in length. The SilverStone SST-CPF04-USA also lists these exact same measurements in its specs. It additionally describes the size as 54mm wide, 19mm high, and 40mm deep, which converts to the same footprint. Both hubs are compact enough to fit in tight spaces without obstructing other components or cables.
Voltage stability
Each hub utilizes a 2200μF capacitor to provide stable voltage to connected fans. This specification is listed in the features for both the SilverStone CPF04 and the SilverStone SST-CPF04-USA. The capacitor helps ensure consistent power delivery, which is crucial for maintaining fan performance and longevity. Since both units rely on this same component value, there is no difference in the electrical stability provided to your eight connected fans.
Speed detection
Both hubs support speed detection for accurately controlling fans. This feature is listed in the specifications for the SilverStone CPF04. It is also listed for the SilverStone SST-CPF04-USA. This capability allows the hub to read RPM data from connected PWM fans and relay it to the motherboard. This ensures your system can monitor fan speeds and adjust them based on temperature readings. Both products offer this same functionality for your cooling setup.
Which SilverStone Fan Hub Fits You
Users wanting explicit 3-pin compatibility info
The SST-CPF04-USA model explicitly details its connector types. It includes PWM 4-pin headers and notes support for 3-pin cables. This specification helps you understand that 3-pin fans will run at maximum RPM without speed control. If you need clarity on how legacy fans operate with this hub, this data-driven listing is the safer choice for your build planning.
Users preferring standard CPF04 model designation
The CPF04 model offers the same core functionality with eight PWM connectors and a 2200μF capacitor for stable voltage. It supports speed detection for accurate fan control. Its dimensions are identical to the other option. If you prefer the standard CPF04 designation and do not require the specific 3-pin usage notes found in the USA variant, this model meets your technical requirements effectively.
Users needing compact mounting with adhesive
The SST-CPF04-USA listing highlights its compact size and includes 3M adhesive for installation. This feature allows you to apply the hub anywhere within your case. While both hubs share the same physical dimensions, the inclusion of mounting tape in this specific model provides a practical installation advantage. You can secure the hub easily without additional screws or brackets.
