Be Quiet's modular Silent Wings 4 fans want to take over all aspects of your PC's cooling

pcgamer.com:

Be Quiet has beenquietly working on a new set of fans for our gaming PCs, the Silent Wings 4 and Silent Wings Pro 4. The hope with these units is that they deliver more universally useful performance in all manner of situation—whether that's as a front of case fan to suck in cool air or attached to a radiator.

Be Quiet is touting both high airflow and high static pressure with both version of Silent Wings 4 fan. That makes a change from the previous Silent Wings 3 fan, which was more for moving air over your components than it was suited to a CPU or GPU radiator. 

Be Quiet has made a few adjustments with the Silent Wing 4 to make this happen, namely by redesigning the blades to get ever-so-slightly closer to the fan frame. All Silent Wings 4 models manage to close up tip clearance to 1mm, down from the 1.2mm on the Silent Wings 3.

The result is around 130.31 m³/h (cubic metres per hour) from the Silent Wings 4 120mm at its balmy top speed of around 2,500 RPM. At a calmer 1,600 RPM, it pushes around 82.74 m³/h. 

If you really want to crank up the performance, and the RPM, the Silent Wings Pro 4 offers a 3,000 RPM mode capable of 142.5 m³/h.

Compare both of those to the Noctua NF-S12B redux-1200 PWM, our favourite PC fan(opens in new tab), at 100.6 m³/h at 1,200 RPM, and you're likely looking at running the Silent Wings at a higher RPM to match that airflow rate. But with the Silent Wings Pro 4 you really can crank up the RPM something fierce if you don't care for the noise.

Where the Silent Wings 4 finds more success is when it comes to pressure. The standard 120mm model manages 1.79 mm/H₂0 at 1,600 RPM, but up to 3.86 mm/H₂0 at full speed. That makes it a great fit for radiators, and up there with the likes of Corsair's
