Compact Design for Small Form Factor Builds

The Pure Rock Slim 3’s space-saving asymmetrical tower design makes it ideal for mini-ITX and HTPC cases where clearance is limited. At just 127 mm tall, it fits comfortably in most compact enclosures without blocking RAM slots or PCIe cards. The silver finish complements modern PC builds while maintaining a professional appearance.

Whisper-Quiet Operation with PWM Control

With noise levels ranging from 12.4 dB at low speed to 24.8 dB at maximum, this cooler operates nearly silently under typical loads. The 4-pin PWM fan connector enables dynamic speed control, adjusting airflow based on processor temperature. The rifle bearing design ensures smooth operation and contributes to the impressive 80,000-hour MTTF rating.

Strong Thermal Performance for Mid-Range CPUs

Three copper heat pipes efficiently transfer heat from the processor to the aluminum fin stack, supporting CPUs with up to 130 W TDP. The 10 cm fan moves up to 35.5 CFM of air while maintaining low noise levels. This makes the Pure Rock Slim 3 suitable for mainstream processors including Ryzen 7, Core i7, and similar mid-range chips.
