Cryorig, a relatively young company, quickly became famous for its efficient and innovative products in the field of CPU cooling. The team of experienced radiator and OC experts rely on high-quality materials and innovative combinations of individual components to get the most out of air coolers. The Cryorig fans in particular are extremely efficient and extremely quiet. The Cryorig QF140 Silent at a Glance:Powerful 140 mm PWM fan for CPU cooler or housingLow noise at 19.5 dB (A)Efficient airflow volume of 42.1 CFMManufacturer\'s warranty up to 6 yearsCryorig\'s QF140 Silent Fan is distinguished by its four additional ventilation slots in the frame of the fan. This increases the efficiency of these fans so that they provide reliable cooling even at low speeds. With this silent variant, the maximum speed is limited to 1,000 RPM. This means that the QF140 Silent\'s noise level remains virtually inaudible at 19.5 dB (A). In addition, the XT140 has an extraordinarily quiet bearing type known as HPLN (High Precision Low Noise). Despite the low speed, the QF140 Silent achieves a full airflow volume of up to 42.1 CFM at an above-average static pressure of 2.12 mmH2O. At low speeds the noise level is nevertheless almost inaudible at 9 dB (A). The fan is also equipped with rubberised decoupling corners. The QF140 Silent is therefore particularly suitable for installation in multimedia platforms or for gamers who do not want to disturb their family members at night while gaming. Registering your product with Cryorig allows you to extend the manufacturer\'s warranty from three to six years.
