Unlike other generic temperature controlled case fans, the ARCTIC F Pro TC fan provides cooling according to not only the temperature, but also the overall necessity for cooling. The revolutionary programmed temperature controller plays a key role. The ARCTIC F Pro TC is programmed to achieve top fan speed at 38C. The fan responds to the rise in temperature swiftly within a critical 6C range, the rpm of the ARCTIC F Pro TC fan increases from around 500 to its maximum of 2,000 rpm Heat is dissipated from the case rapidly in order to achieve immediate cooling. As a result, the case air temperature remains at 38C or below and thus the possibility of having a system failure can be eliminated. The accurate temperature sensor of the ARCTIC F Pro TC is equipped at the end of a 40cm cable. This gives much better flexibility when choosing the most appropriate spot that users would like to have the temperature detection.
