The tower CPU Cooler 'Tranquillo' uses 4 power heat pipes and a special heat pipe constellation to achieve best heat transfer from CPU core to the aluminium fins in its class. After precise software simulation and calculation during the development stage a unique heat sink shape was created to lower air flow resistance as much as possible. A silent 120mm fan with the intelligent GELID PWM (Pulse Width Module) control has been chosen to make this heat sink more valuable. The fan blades were optimised to guarantee high airflow while running silently. The intelligent GELID PWM curve keeps the fan silent when no necessary cooling is needed and accelerates the fan speed whenever additional cooling is needed. The multi-award winning high performance GC-2 thermal compound is already included in the package.
