BeQuiet! Pure Loop 2
In the lower class of BeQuiet! liquid coolers, the new Pure Loop 2 models replace the old (Pure Loop) models in up to four formats. This means that this news may be of interest to users of SFF systems as well as those on the opposite end of the spectrum, with full tower cases. The key changes between generations are the pump upgrade (finally with PWM control) as well as fans with higher static pressure.
The new Pure Loop 2 liquid coolers starting at 90 Euros (for the 120mm variant) represent an affordable option in the BeQuiet range that is categorically still below the Pure Loop 2 FX. The main difference here is that the latest liquid coolers without the “FX” in the name don’t use ARGB fans, but the brightly coloured lighting lining the block cover is still there.
Compared to the previous Pure Loop models, a new pump with PWM control is used (the pump speed in the older Pure Loop was only adjustable by linear/DC). The pump can thus be comfortably slowed down (the stated operating range is 4000–5500 rpm).
Pure Loop 2 coolers are available in all formats, from 120 mm to 240 mm, 280 mm and all the way up to 360 mm.All use Pure Wings 3 fans, which are geometrically based on the Light Wings 2 high-speed models. The difference seems to be mainly in the Pure Wings 3 not having a circular light guide around the rotor with ARGB LEDs, and in the lower speed (even at maximum performance, this will keep the fans from getting into a very noisy band with worse scaling of the excessively high flow with cooling performance). The Pure Wings 3 reaches “only” 2100 rpm, or 1800 rpm if it’s the 280mm variant with 140mm fans.
Assuming that the rotor and frame design of the Pure Wings 3 fans is really no different from the Light Wings 2, we can conclude that the same airflow through the radiator will be achieved at a lower noise level than the previous models. This claim is based on our comparison of the Light Wings 2 (Pure Wings 3) fans with the Pure Wings 2 (on the Pure Loop 1), and with operation on radiators. So there probably should be some improvement in cooling efficiency. You’ll find out where these liquid coolers rank alongside competing solutions later in our tests.
Coolers BeQuiet! Pure Loop 3 can be installed on Intel LGA 1700, 1200, 115x and AMD AM5 and AM4 platforms.
