be quiet! Pure Wings 2 PWM 140 (BL040)
 | Expecting restock $30.68 Large, low speed, low noise, 140mm PWM fan with a standard 4-pin motherboard header. It is positioned as a product of the upper part of the middle price category, focused on use in computer cases and large two-section tower-type processor coolers. It differs from models from other manufacturers in its original external design, the use of advanced screw-threaded plain bearings and a special shape of the blades, which allows you to get a more efficient focused air flow that does not create significant noise. The declared level of acoustic comfort of the be quiet! Pure Wings 2 PWM 140 can be called excellent, the noise does not exceed 20 dB at a maximum speed of rotation of the blades of 1000 rpm. In this mode, the fan delivers up to 1.73 m³ of air per minute. The resource of the device decla...red by the manufacturer is 80,000 hours and this is more than 9 years of continuous operation, which is more than enough for home use. PWM control allows compatible controllers (including those used on motherboards) to flexibly adjust the impeller speed and noise level. Thanks to this control system, a properly configured motherboard will be able to independently increase the speed when necessary, or reduce them to ensure a quiet operation of the system. |
