GlacialTech is a company whose business is cooling. They provide thermal solutions for desktops and server systems, everything from efficient case designs and power supplies to heat sinks and cooling fans. The company's offering to the gaming community is the UFO V51. It comes in two flavors-- Silent and PWM-- the variance coming in the form of a fixed fan speed (1600 RPM) and low noise output for the Silent and a variable fan speed (800-2500 RPM) for the PWM and higher max noise output for the PWM.GlacialTech UFO V51 Silent Review
