Just make sure it’ll fit in your case. The arctic coolers are thicc boys. I have a 420 pro rgb and it’s great, cools my 285k system easily. Paired it with a thermal grizzly phasesheet ptm and it’s been knock wood rock solid last few months. Had an old non rgb non pro 420 for 6ish months with no issues at all, only swapped because I wanted RGB Answer from PaulNY on reddit.com

March 28, 2025Arctic Liquid Freezer III Pro Review: The best AIO for Ryzen 9950X3D, and Intel too
If you want a silently running cooler running less than 38.2 dBA, you’ll need to run the pump at less than maximum speeds. Most people will never run the pump at maximum speeds, as it's easier to use the single-PWM control option (one PWM signal for rad fans + VRM fan + pump speed, of course with different values mapped per %). The review mentioned that, but didn't show the handy diagram Arctic prepared, which I think helps explain how it works: https://imgur.com/a/amqoU0U From here: https://www.arctic.de/us/Liquid-Freezer-III-Pro-360/ACFRE00180A I appreciate Arctic's flexibility, so you can really dial it in, or just use basically the easiest AIO control option: like an air cooler, one CPU fan header controls everything.

March 28, 2025 - The LFIII Pro 360 outperforms the LFIII 420 in the benchmark, so probably better pump and coldplate too ... Just looked it up. The original is also 38mm. https://www.arctic.de/us/Liquid-Freezer-III-360/ACFRE00136A
