The XED120 WS is a high-performance dual tower heatsink cooler engineered specifically for the most demanding server CPUs, compatible with both Intel and AMD server sockets. It boasts an impressive TDP of 450W, achieved through the use of 8 aluminum heatpipes and a dual-heatsink design, complemented by a server-grade dual-ball bearing fan. This fan operates within a PWM range of 800 to 3,000 RPM, delivering over 102 CFM of airflow at maximum speed to provide cooling power far surpassing consumer-grade PC fans. Built for continuous operation, the 120mm fan is designed to handle the rigors of server environments. Measuring 145mm in total height, the XED120 WS fits comfortably within 4U rackmount chassis, eliminating any concerns about height restrictions. Its high-quality construction ensures consistent, reliable cooling by maintaining firm contact between the copper base plate and the CPU heat spreader, effectively managing the intense heat generated by server-grade CPUs in demanding environments. For those that can't deploy servers with liquid cooling, the XED120 WS is an excellent substitute to achieve the best CPU cooling possible in 4U form factor.
