be quiet! Pure Wings 2 PWM 140 (BL040)
 | Outdated Product 429 ₴ Large, low speed, low noise, 140mm PWM fan with a standard 4-pin motherboard header.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. |

Bought 4 pieces of these from a German site for the Aerocool Aero 1000: two for intake in front, two on top for exhaust. They have been working for over two years, without maintenance, no noise, no play. Excellent coolers. Highly recommend to everyone! Reliable, Quiet They are not available |
I bought this cooler for the front panel of the case to provide airflow throughout the entire system, cooling the video card and expelling hot air from inside. Previously, I had already purchased a similar one from this 120 series for my water cooling system, as my old one had a cheap noisy cooler. Essentially, they only differ in size, and this one has a maximum of 1000 RPM, while that one has more, about 1500, if I remember correctly. Regarding the noise, I can say that just like the 120, even at maximum RPM, you'll only hear the airflow, with no extraneous sounds. If you reduce the speed to 60-70%, there's practically no noise from the air. These coolers are just perfect for price-quality ratio. The only thing they don't have is the trendy RGB lighting, which might be a downside for some, but if you're looking for the most silent and efficient cooler specifically for cooling the system, you won't find better. I highly recommend these coolers, and the entire brand is excellent. Their components are superb, maybe slightly more expensive than usual prices, but definitely worth it. Quiet, efficient, affordable. No drawbacks  Vіktor S.: use be quiet! Pure Wings 2 PWM 140 less than month |
In general, I bought these 2 fans. The result: mixed feelings. On one hand, I am satisfied with the purchase, but on the other, not completely. One of the fans came with a defect. The bearing buzzes. Maybe it's not the bearing's fault, but the point is that the fan buzzes like Chewbacca's child. There's no such problem with the second fan, and it works really, really quietly, which makes me happy. If someone is wondering whether to buy it or not, my personal advice is to buy. Why? Because it fulfills its task 100%, and, which is very important for me, it works almost silently (if not a defective version, of course). You can hear it only if you bring your ear directly to the blades, but in that case, any fan would make noise, so such a test is meaningless. As for the defect, of course, it's very upsetting and leaves a bit of a disappointment. I often ordered goods from Rozetka and never usually had any problems, but now this... Quiet, low cost. Got married. use be quiet! Pure Wings 2 PWM 140 less than month |
