The GELID Solutions CC-Ssilence-APLUS is a compact, high-performance and whisper-quiet CPU cooler, ideal for use in Mini ITX, Micro ATX, ATX, HTPC, Panel PC, Car PC and 1U server. It features two high-power heat pipes to achieve a fast and efficient heat transfer from core to aluminum fins. It's outfitted with a frameless 65mm fan, which generates a large volume of airflow to maximize cooling performance. The silent fan features a GELID intelligent PWM (Pulse Width Modulation) control which enables silent operation at low CPU temperature and fan speed acceleration when the CPU temperature climbs higher. This results in a perfect balance between airflow performance and noise level. Plus, the fan has a ball bearing design for long-lasting durability.
