The Cooler Master HAF II 500 PC case is built around a singular principle: maximum airflow. This is achieved through its most prominent feature, two enormous 220 mm "Mighty40" fans housed in the front, supplemented by a 180 mm fan at the rear. These large-diameter fans spin at relatively low RPMs (1,050 RPM for the front, 1,370 RPM for the rear) while moving an impressive volume of air, rated at 203.8 CFM for the front fans and 161.5 CFM for the rear.
Design and Build Experience
The HAF II 500 is a spacious chassis, measuring 557 x 262 x 548 mm, which accommodates E-ATX motherboards up to 310 mm wide. This generous internal volume translates into a straightforward building experience, with ample clearance for large CPU coolers and long GPUs up to 430 mm. Cable management is made easy by a traditional layout combined with effective cable covers that conceal most routing. However, the case utilizes non-captive thumbscrews with small, easily lost washers, and the included GPU support bracket, while accommodating dual GPUs, offers limited adjustability.
The aesthetic of the HAF II 500 is understated, featuring a clean, traditional design with a polished plastic front panel. While functional, it lacks the flair of some more contemporary cases. Some minor rough edges were noted on the plastic components upon close inspection.
Features and Cooling Performance
Cooler Master has integrated a fan hub on the rear of the motherboard tray, offering six PWM fan headers and six ARGB headers, simplifying the connection of the included fans and any additional components. The case also includes a rail system, dubbed MasterRail, which allows for flexible radiator mounting at the top (up to 420 mm) and front. Three easily accessible dust filters are present for the front, top, and PSU.
In thermal testing, the HAF II 500 demonstrated its capability. Even with fans set to 70% speed, which significantly reduced noise levels from a noticeable whirr at 100% (50 dB(A) from 50 cm), component temperatures remained stable. During 3DMark's Speedway benchmark, the GPU measured 71°C and the CPU 35°C at 70% fan speed, nearly identical to the results at full speed (GPU: 70°C, CPU: 35°C).
An airflow test using an anemometer showed minimal reduction in air velocity (2.3 m/s with front panel and dust filter) compared to removing the front panel (2.8 m/s), indicating the front design does not significantly impede airflow.
Value and Conclusion
At $200 / £250, the Cooler Master HAF II 500 sits at the higher end of the PC case market. While its exceptional airflow and included fans help justify the cost, more affordable high-airflow options exist, such as the Havn BF 360 or Phanteks Eclipse G400A. However, when compared to some premium alternatives like the Antec Flux Pro Noctua Edition, the HAF II 500 presents a more compelling value proposition for users prioritizing cooling performance above all else. Its ease of build, robust cooling, and tidy cable management make it a solid choice for those concerned about thermal loads, provided the price is within budget.
