We measured the noise output of our entire system from a distance of 1m while the CPU cooler's fans operate at 100% (indicating the maximum noise output).
Lower noise levels can be achieved by utilising the Sapphire Vapor-X CPU cooler's 4-pin PWM operated fans.
An exact mirror image of the thermal performance charts, noise output is an area where the Vapor-X is able to shine. While 43.2 dbA may not be the lowest value of today's competitors, the cooling performance per unit noise ratio looks to offer a well-thought balance.
Utilising the fans' PWM function will allow even lower noise levels to be achieved when the highest possible cooling performance isn't required.
