Who it fits

Key specs explained for this cooler

TDP Rating: 235W

This rating indicates the maximum thermal output the cooler is designed to handle. You can use it with high-performance CPUs that generate significant heat. It ensures the fans and heat pipes move enough air to keep temperatures stable under load. When shopping, compare this number to your processor's thermal design power to ensure adequate cooling headroom.

Heat Pipes: 4

The unit uses four copper heat pipes to transfer heat from the base to the fins. This count is standard for single-tower coolers and helps distribute thermal energy efficiently. More pipes generally mean better heat dissipation for the same fan size. You should check this number against other air coolers to gauge their potential thermal conductivity and overall cooling efficiency.

Tower Design: Single-Tower

A single-tower design features one stack of fins and one fan slot, often with a second fan added for push-pull airflow. This configuration is ideal for mATX cases or builds with limited space. It offers a balance between cooling performance and physical size. When comparing options, consider this form factor if you need a compact solution that still delivers strong thermal results.

Socket Compatibility: LGA1851/1700/1200/115X, AM5/AM4

This cooler supports a wide range of Intel and AMD sockets, including the latest LGA1851 and AM5 platforms. You do not need to buy a different unit if you upgrade your motherboard or CPU within these families. Always verify your specific socket type before purchasing. Broad compatibility saves you from searching for new mounting hardware when building or upgrading your system.

Lighting: ARGB

Addressable RGB lighting allows you to control each LED individually for custom color effects. You can sync these lights with your system's software for a cohesive aesthetic. This feature is useful for users who want to match their cooler to their case or other components. When looking at other coolers, check if they offer similar software integration for lighting customization.

Design and build details

The cooler features an all-white tower and dual ARGB fans. A pixel-style top display and orange accents create a clean look. The fan hub uses a CD-pattern silver finish. According to the listing, this design serves as a focal point for glass-panel and white gaming builds. It suits users who prioritize visual consistency in their setup.

Dimensions are 4.8 inches wide, 6.1 inches high, and 4.53 inches long. The unit weighs 1 pound. This single-tower layout uses four 6mm direct-touch copper heat pipes. The front fan has standard blades, while the rear fan has reverse blades. This push-pull configuration moves air through the fin stack to handle up to 235W TDP. The reverse-blade design preserves the illuminated view without disrupting intended airflow.

Cabling uses a 7-pin interconnect to reduce visible clutter. Separate connections handle PWM power, 5V 3-pin ARGB, and USB 2.0 for the display. The current white batch uses shorter cables. According to the listing, this is not recommended for full-size ATX routing. It is better suited for mATX builds. You must remove the rear fan before mounting, then reinstall it. The display requires darkFlash software on Windows 10 or 11 to show CPU or GPU data.

Setup and everyday use

Installing this cooler requires a specific sequence. You must remove the rear fan before mounting the unit to the motherboard. After securing the tower, you reinstall the rear fan to complete the push-pull airflow configuration. The listing notes that the current white batch uses shorter cables. This design choice is not recommended for full-size ATX cases because routing may be tight. It is better suited for mATX builds where space is more constrained.

For connectivity, you will need separate ports on your motherboard. The cooler uses a 7-pin fan interconnect to reduce visible clutter between the two fans. You must also connect PWM power, 5V 3-pin ARGB, and a USB 2.0 header individually. This setup allows the digital display and lighting to function correctly.

In daily use, the cooler handles thermal loads up to 235W. It supports Intel LGA1851, 1700, 1200, and 115X sockets, as well as AMD AM5 and AM4. The digital display on top provides real-time system data. You can view CPU or GPU temperature, load, power, frequency, voltage, fan speed, or memory data. This information is accessed by installing darkFlash software on Windows 10 or 11. The software lets you switch temperature units between Celsius and Fahrenheit. The reverse-blade rear fan maintains intended airflow while keeping the ARGB lighting visible. This configuration ensures your system remains cool while displaying relevant performance metrics.

Before You Buy This Cooler

Before you commit to this white single-tower, verify your case dimensions. The unit measures 6.1 inches in height and 4.8 inches in width. You must check that your RAM sticks do not interfere with the dual ARGB fans. Since the current batch uses shorter cables, this cooler is not recommended for full-size ATX cases with complex routing. It is better suited for mATX builds. You will need to install the darkFlash software on Windows 10 or 11 to access the digital display features. This allows you to monitor CPU temperature, load, and fan speed. The 7-pin fan interconnect helps reduce cable clutter, but you still need separate connections for PWM power, 5V ARGB, and USB 2.0. Ensure your motherboard has the required headers. This cooler fits well alongside other white-themed options if you prioritize aesthetics and compact size over extreme overclocking potential.

Check before you buy

• Check RAM clearance against the dual ARGB fans
• Verify case height allows for the 6.1 inch tower
• Confirm motherboard has 5V ARGB and USB 2.0 headers
• Ensure your case supports mATX cable routing
• Download darkFlash software for display functionality
