The Pure Loop 2 FX 360 from be quiet is an improvement in terms of performance versus the Silent Loop 2 360mm we have tested a while ago, mainly due to the increased performance of the included fans, the Light Wings 120mm which now have a maximum rotational speed of 2500RPM instead of 2100. Even if the pump does have a high RPM, it remains very silent during operation thanks to the double decoupled design, while the ARGB effect complexity is managed by the system motherboard.
