Koeler Silverstone AR12 RGB processor

The SilverStone AR12 RGB Processor Cooler (SST-AR12-RGB) is a compact CPU air cooler featuring four Ø6 mm copper heat-pipes, 0.4 mm aluminum fins and an integrated 120 mm PWM RGB fan. With dimensions of 128 × 75 × 154 mm and a weight of 0.632 kg, it is designed to fit a wide range of desktop CPU sockets while providing improved heat transfer and a modern aesthetic in black, stainless steel and white finishes.

Advantages

Four Ø6 mm copper heat-pipes and thin 0.4 mm aluminum fins increase heat conduction from the CPU to the fin array. Heat-pipe direct contact (HDC) places the pipes in direct contact with the CPU heatspreader for more efficient thermal transfer. The 120 mm PWM RGB fan offers variable speed control from 700 to 2200 RPM for balance between cooling performance and noise. The fan uses a hydraulic bearing for quieter operation and includes RGB lighting that can be controlled via compatible motherboards or an RGB controller.

Suitable for

• Cooling mid-range desktop CPUs in compact or standard towers
• Systems requiring RGB lighting coordinated with motherboard controls
• Builds where a balance of airflow and low noise is desired

How to use

Install the cooler following the motherboard and SilverStone mounting instructions for the specific CPU socket. Apply a thin, even layer of thermal paste to the CPU heatspreader, align the cooler so the heat-pipes make direct contact, and secure the mounting brackets. Connect the 4-pin PWM fan header to the motherboard for speed control and connect RGB cabling to a compatible RGB header or controller to enable lighting. Ensure adequate clearance in the case for the cooler dimensions before final installation.

Recommendations

For best thermal performance, confirm compatibility with your case and motherboard headers. Use motherboard fan controls or software to set fan curves that balance cooling and noise. Periodically clean dust from the fan and fins to maintain airflow efficiency.
