This increases the efficiency of these fans so that they provide reliable cooling even at low speeds. This Silent variant is limited to a maximum speed of 1.000 RPM. This enables the QF140 Silent to function at a barely audible 19,5 dB(A). Additionally the XT140 uses an extremely quiet bearing type known as HPLN (High Precision Low Noise). In spite of the low RPM the QF140 Silent is capable of a full air flow volume of up to 44 CFM with an average static pressure of 2,12 mm H2O. At low speeds the noise produced is 9 dB(A). The QF140 Silent is designed for installation in multimedia PCs or for gamers who want to avoid disturbing members of their family while gaming at night.
