First thing I want to say is to check the dimensions of your case because this thing is HUGE! My editing system is running a Ryzen 9 5950x that is heavily overclocked, so I needed something to cool it properly. I have tried high-end air coolers and basically every AIO from 120mm and up. After reading reviews and watching some YouTube videos, I decided to grab the Arctic cooler. I have an old Thermaltake Core P3 and it technically has mounting for a 420mm radiator, but I can tell you from experience that you can't actually put all the screws in because the slots on the case aren't long enough. Mounting the pump/cold plate was pretty easy and the inclusion of the ability to offset it for Ryzen chips was one of the reasons I bought this particular cooler. The VRM fan does help though it's not really needed on the Asus X570 dark hero because the heatsinks work quite well. Temps never get above 65C when running Aida64 and never get above ~45C when gaming. The fans are quiet and push enough air so that I can run them at a minimum. The RGB is bright and easily controllable using motherboard software. If you have the room for this cooler and have a CPU that needs it then this is a must buy. I am 100% happy with this purchase and will be putting Arctic coolers in my builds from now on. ... show more

    • Best cooler, but make sure your case can support it
Honestly, there isn't any CPU that this thing can't handle. It has the power, the noise, and the looks, it keeps anything it touches cold. BUT, be very careful. Make sure your case can handle it. I have a lancool 3, and it doesn't fit. This thing is a large beast, and larger than a regular 420 cooler, the main piece being the thickness and the length. It's barely just too long. If your case can fit it, then get it. If it can't, get the 360 since that thing is also a beast. ... show more

    • AMD CPU Hot Spot Offset Optimization = 30° C improvement swapping out another OEM's AIO!
Review Image by Swift & Makers ✅ Swift & Makers ✅
Fed up after 18 months with another OEM's 360mm AIO inability to efficiently cool a non-overclocked Ryzen 5950x CPU; it struggled to maintain a CPU temp in the high 70°s without load, but worse, shot up to just below or even frequently at the 90° safeguard cap under load. I did try a few intermittent troubleshooting tactics on old AIO, such as reapplying thermal paste and ensuring secure mount, etc., but to no avail, so I finally elected to seek out and replace with a new cooler by purchasing this unit. Immediately after install into my preexisting build, the Arctic LF-II 420 proved amazing cooling improvement out-of-the-box, logging sustained very low 40°s no load, and no more than high 50°s / low 60°s under load. Granted that's moving from 360mm previously installed, to this 420mm, but nevertheless, I hadn't expected such gains, and would have been satisfied with half as much, particularly for a high-performance 16-core CPU. In addition to swapping in the larger Arctic rad, which is not only 420mm, but a very brawny 38mm thick, I believe the massive cooling improvement after installing this AIO, may be equally, if not more so attributed to Arctic's LF-II optional "offset" mounting feature that addresses the AM4's 5000 series chiplet based CPU construction which shifts the CPU hot spots from center to bottom 3rd of CPU top surface. In turn, the offset mounting bracket (included) centers the cooling plate on the hot chiplets, not the lower temp non-hot spot center of the CPU. Simple but ingenious innovation. There may be other AIO OEM's that offer this offsetting feature for respective AM4/AM5 Ryzen series, but it wasn't offered by the outgoing AIO I had installed, which provided a very compelling comparison. Very highly recommended for AMD Ryzen CPU's series with offset hotspot areas. Other notes: If going the 420mm rad like me, be sure to account for not only the supersize length and width, but also the increased height too (including fans). I have a very large ATX-E case and knew that I could schematically accommodate the 420 size and mounting format, but due to the rad's height, I had make several unforeseen adjustments to placement of a few other components in my setup as well as offset from the case's dedicated 420 screw mounts, giving up use of 4 of the twelve screw mounting points. This meant more time for the install, but not a product issue at all, and using only 8 of 12 screw mounting points still ensured very solid and stable install. Also, it's difficult to determine by the included pic alone, but I'm utilizing a 'push' air INTAKE top-mounted configuration (vs pre-assembled 'pull' air EXHAUST setup), and a 6-fan double push setup (3 above and 3 below rad). Inside the case (shown top of case in pic) are 3 non-Arctic 140mm RGB fans mounted to bottom of rad, as well as (not visible) the 3 included Arctic static pressure 140mm fans, which are mounted in the case's top compartment to the top of the rad / case rad mounting bracket. The Arctic140 fans produce excellent airflow and are sturdy build quality. ... show more

    • Top notch performance but CPU fan settings tweaks required.
Edit 2: The AIO pump/40mm pump fan needs to be spinning at about ~31% RPM minimum to avoid the noise. Under about ~31% the noise is present but becomes silent above it. This may not be set by default in your BIOS or if you use the Fan control program. Adding 2 stars. This AIO replaced a Corsair h115i (280mm) that I have mounted to a i9-12900k Per numerous reviews, it was said that Arctic AIOs are the quietest out there. Yeah, no. Not even close. The tiny VRM fan on the pump head is LOUD. Not as high pitched but as if there's some friction going on. Installing it is a pain. I ended up having temporarily tape the back plate of the motherboard, thread the standoff screws then remove the tape. Wasn't happening otherwise. Now once it's installed? An absolute monster. On idle Corsair : 30-32C Arctic: 25-28C Cinebench 23 multicore Corsair: 95-98C Arctic: 86-88C While this is a 420mm (140mm x3) vs a 280mm (140 x2), the 10C is pretty huge. That said, Cinebench can and will eat all the horsepower you can throw at it and unless you're a content creator, you're never going to hit that. General use + gaming? Get something like the Corsair. Easy to install and great temps. For content creation or overclocking? The Arctic. ... show more
