Until recently there were seven coolers with the name “Hyper” among products from Cooler Master Co., Ltd. They are Hyper Z600, Hyper TX3, Hyper 212, Hyper 212 Plus, Hyper N520, Hyper N620 and a monster-cooler – Hyper 101. Now there is the eighth member in this lineup, which is available in two different modifications: Cooler Master Hyper 612S and Cooler Master Hyper 612 PWM. The difference between the first and the second cooler modifications are minimal. The “S” model features a slightly slower fan and a silver decorative cover instead of a black one. That is why today we are going to talk about the more interesting one of the two – Hyper 612 PWM.
