The revolutionary programmed temperature controller plays a key role. As shown in the chart, when case ambient air temperature is at safe level 0°C to 32°C, the ARCTIC F Pro TC fan speed remains at its lowest (500 rpm). This is to offer adequate ventilation at the lowest noise level possible. The ARCTIC F Pro TC is therefore completely inaudible (0.05 sone) at low temperatures – a much quieter level than generic TC fans.
However, once a gaming system is at load, the case ambient air temperature will go up speedily, and without any case fans, most likely it will rise above 40°C, an overheated level for most PC cases. High performance and instant cooling is vital at this stage in order to eliminate the risk of overheating and system instability.
