The Argon series coolers are designed to provide the best cooling solution for your CPU. The Argon AR01 features three 8mm thick copper heat pipes connect to the base using heat-pipe direct contact (HDC) technology. A new, compact 120mm PWM fan with excellent balance of airflow and noise is included to provide forced-air heat dissipation with the ability to cool components around the CPU area. For users requiring higher performance cooling at reasonable price, AR01 is a great choice.

With varying distances between fan gaps, the resulting pressure differences forces air to travel up and down along the fins in more turbulent manner. This delays airflow from escaping the heatsink and thus taking more heat away.
