CPU cooler Alpenföhn Brocken 4 ARGB with 120mm fan, black

The Alpenföhn Brocken 4 ARGB with 120mm fan in black is a CPU air cooler that combines a tower-style heatsink with an addressable RGB fan and PWM control. It is engineered to transfer heat away from desktop processors through a stack of aluminum fins and multiple heat pipes, while the included 120mm fan provides adjustable airflow and ARGB lighting for system integration. The design focuses on compatibility with a range of CPU sockets and straightforward installation in standard mid-tower and larger cases.

Advantages

The cooler offers balanced thermal performance for mainstream and mid-range processors, with a compact tower profile that optimizes clearance for memory modules and motherboard components. The PWM-controlled fan enables automatic speed adjustment according to CPU temperature, while the ARGB lighting supports synchronization with compatible motherboards and controllers. The black finish and understated styling make it suitable for systems where both functional cooling and subtle aesthetics are required.

Suitable for

• Air cooling for desktop CPUs in gaming and productivity builds
• System upgrades where improved CPU temperature control is needed
• PC builds requiring addressable RGB lighting integration
• Mid-tower and full-tower cases with sufficient CPU cooler height clearance

Key specifications

• Cooling type: Air cooler with tower heatsink and fan
• Fan size: 120 mm
• Fan control: PWM (automatic speed control)
• Lighting: Addressable RGB (ARGB) compatible with standard 3-pin headers or controller
• Heatsink material: Aluminum fins with multiple heat pipes for heat transfer
• Finish: Black

How to use

Install the cooler by mounting the supplied bracket and backplate to the motherboard following the manufacturer’s mounting instructions for the specific CPU socket. Apply a thin, even layer of thermal paste to the CPU heatspreader, position the heatsink over the processor, and secure it with the provided screws or retention mechanism to ensure firm contact. Connect the fan’s PWM cable to the motherboard CPU_FAN header and the ARGB cable to a compatible 3-pin ARGB header or controller. After installation, verify fan operation and lighting in the system BIOS or RGB software and monitor CPU temperatures under typical workloads.

Usage recommendations

Use the Alpenföhn Brocken 4 ARGB with a properly sized case and ensure at least the recommended cooler height clearance for your chassis. Keep airflow unobstructed by arranging case fans to maintain front-to-back or bottom-to-top airflow. Clean dust from the heatsink fins and fan blades periodically to maintain cooling efficiency. For consistent thermal performance, confirm the fan is connected to a PWM-capable header and enable automatic fan control in BIOS or fan-control software.
