Time to continue coverage of the Silent Wings 3 fans from be quiet!, with the 120 mm standard version already covered here. After what seemed like ages, these much awaited fans are finally out, and I am always excited to test more 140 mm fans. I truly believe we have reached the point where 120 mm fans are not the best for all applications anymore. Let’s see what be quiet! brings to the table now, and thanks again to them for the review samples.

Please note that there are multiple versions of the Silent Wings 3 fan series. Today we take a look at the 140 mm and 140 mm PWM non high-speed versions. They only differ in mode of control and some accessories, so let’s take a look at the specs of the non-PWM version courtesy the product page:

I will never tire of appreciating 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 1000 RPM which seems fair considering be quiet! company philosophy on prioritizing noise and also knowing there are high speed versions available. Both have their new 6-pole motor which is fairly efficient as seen from the power ratings above, 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 140 x 140 x 25 mm square frame fans with a similar twist to the Silent Wings 2 fans in that the corners are removable and exchangeable. Let’s now take a good look at the fans on the next page.
