ARCTIC Fan Pro 2L TC

Arctic Fan Pro 2L TC Temperature Controlled Fan
Fan Speed - Temperature Graph.
The graph will be interesting between 20 und 45°C. In this range, the fan works virtually silent between 1000 - 2100 RPM.

More Efficient Ventilation
The cooling of each PC Component is based on warm air being drawn out of the case.
In most cases the power supply cannot provide enough ventilation for the PC case without having the fan inside the power supply spin at higher rotation speeds and thus creating more noise.
A additional case fan such as arctic fan PRO 2L TC can solve this problem. The fan inside the power supply can now spin at lower speeds and thus work far quieter.
The ventilation in a PC case using two fans causes, for an equal airflow less than half as much noise.
(10 parallel running fans are perceived to be twice as loud, which could compare to an increase of approx. 6dB)

Quiet Fan
The fan case has been reworked and disturbing humming noise minimized.
