The be quiet! Silent Wings 3 series of fans have been mostly impressive, with the standard speed 120 and 140 mm variants already reviewed here before. Along with these, I was fortunate enough to also receive the high-speed versions of both which are, as logic would dictate, higher speed rated fans with higher max airflow, static pressure and noise ratings accordingly. These are be quiet! answer to the different demands of the PC DIY market- the Europeans prefer silence, the Americans and Asians want more performance. So let’s see how these work out beginning with the 120 mm version now.

As with the other Silent Wings 3 fans, these come in a choice of DC or PWM control. They only differ in mode of control and some accessories, so let’s take a look at the specs of the DC voltage control version courtesy the product page:

As always, I appreciate be quiet!’s consistency in having a detailed, comprehensive set of product specifications. The PWM version is missing the 12 V to 7 V and 12 V to 5 V adapter (and also a 12 V from PSU adapter, as we will see. All of these are on a single adapter, in fact). That aside, they are identical in every other way sans the mode of fan control and fan cable connector of course. Both are rated at 2200 RPM, both have the new 6-pole motor and both have their FDB bearing resulting in a promised lifetime of a whopping 300, 000 hours. The warranty of 3 years comes as a let down then, as such confidence would be better accompanied with a 5 year warranty. These are 120 x 120 x 25 mm square frame fans with a similar twist to the Silent Wings 2 fans in that the corners are removable and exchangeable. The high-speed versions are new in be quiet! inventory in that their Silent Wings 2 series did not have such options. Let’s now take a good look at the fans on the next page.
