Let’s start off with noise performance from each cooler at 100% fan speed.
This is important as it sets the precedence for which coolers we expect to deliver the higher levels of performance based on the faster and louder fans. Assuming that their performance is efficient in comparison to their noise output levels, that is.
The chassis fans are disabled, all case panels are on, and the sound meter is placed 12 inches from the side of the Fractal chassis’ glass side panel – roughly where a desk user will be sat.
Starting out with noise results at full fan and pump speed, the Arctic Liquid Freezer II 360 A-RGB performs very well. In fact, this is the quietest AIO cooler that we have tested to date. And with those superb Arctic P12-based 1800 RPM fans, the noise output is actually better than many high-end air coolers.
42.0 dBA at full fan and pump speeds is absolutely fine to set next to for a working or gaming session. I would have no worries about running the Freezer II 360 level of noise on a 24/7 basis, but the excellent PWM fan speed range is also available.
Very impressive indeed! Though with this noise level, thanks to modes speed fans by AIO standards, we do wonder if full-speed thermal performance will be compromised slightly. Let’s find out.
