be quiet! Silent Wings 4/Silent Wings Pro 4 120mm Review

Earlier this month, be quiet! officially announced the launch of its brand new Silent Wings 4 and Silent Wings Pro 4 cooling fans. Designed to offer exceptional performance as case fans, on heatsinks, or as a replacement/upgraded AIO radiator alternatives, with the full series comprising of eight new models in total, there was a lot going on, but it certainly all looked pretty impressive!

With be quiet! kindly sending us a number of samples from the series, therefore, it would’ve been rude of us to not check them out to see just what kind of improvements consumers can expect from these new variants which are now available to purchase worldwide!

For this review, we will specifically be focusing on three of the main variants throughout this new series. Given the general similarities between them, it seemed a bit pointless covering them individually, but rest assured, we will look at some of the key highlights on offer here and particularly so in regards to the Silent Wings Pro 4.

Just for clarification though, this review will specifically cover the following variants:

• Silent Wings 4 120mm PWM
• Silent Wings 4 120mm PWM High Speed
• Silent Wings Pro 4 120mm PWM

At this point though, we might as well get one elephant out of the room by letting you know what the key differences are between the standard and ‘Pro’ models. In a nutshell, while all fans are more than suitable for general system cooling, the ‘Pro’ series has taken a specific additional design focus on higher levels of fan speed control functionality as well as offering vastly improved support and performance as AIO radiator replacements/upgrades.

Don’t worry though, we will highlight all of the key individual features as we go through this review – Where aspects are the same though, for the sake of brevity, we will just cover the point once.
