Hyper H411R The Hyper H411R is an affordable, compact and high performance air cooler that is a great fit for small form factor system. With 4 heatpipes and Direct Contact technology, this outperforms its predecessor Hyper 103. The special fin design optimizes air flow toward heatpipes. Its 92mm PWM fan features a wide fan speed range and can be fine tuned for maximum airflow and cooling performance or silent operation. Performance in Compact Size With height of 136.5mm, the Hyper H411R is a compact tower cooler, designed to fit in tight builds. With its outstanding performance in its class, it is a great solution for Micro-ATX and Mini-ITX boards. 4 Direct Contact Heatpipes Just like the Hyper 212, it includes 4 Direct Contact heatpipes constructed out of copper to accelerate the heat conduction through the entire heatpipe. This allows heat to be dissipated quickly and efficiently throught the funnel shaped aluminum fins. Perfecting the Heatsink Design Cooler Master's years of aluminum fin craftmanship is second to none. Optimised fin stacked distance between each layer is based on stringent airflow tests from our labs. As a result, even with a compact-size each heatsink with the 92mm fan is able to maintain performance in a compact build. Easy Installation Tool-free mounting system ensures hassle-free installation. Universal retention brackets are compatible with latest Intel and AMD socket CPU.
