I decided to use this for a new build after seeing it highly rated in multiple articles about the best AIO coolers you can get in 2023. Now that I've tested it, here's my breakdown of the pros/cons:Pros:- Aesthetics — The cooler looks great. While this version doesn't have the rotatable face-plate the non-SE versions do, the infinity-mirror effect is pretty while still fitting in to a minimal build. I don't like the "gamer" flair that a lot of PC pieces have these days (and wouldn't have even cared about any RGB in my build), so this was a win for me. The tubing looks and feels nice and isn't too long or too short to be manageable.- Functionality — It's keeping my 7900X right around 80° C which is pretty good. I didn't change the thermal paste (which comes pre-applied) and even had to fiddle with the plate after installation, so it must be pretty decent paste.Cons:- Installation - Instructions — The installation in general wasn't great for me, so I'm breaking this down further, starting with the instructions. Or, I should say, the lack of instructions. You get a little paper foldout with all of the instructions and no real elaboration. I would've highly preferred a QR code to an installation video like Arctic does, or at least more fleshed-out instructions. I really wanted to know if I could rotate the orientation of the brackets so the tubing and pump cables came out a different side, for instance. Also, one of the first steps it mentions is the part where you remove the plastic over the CPU block. SKIP THIS STEP UNTIL LATER! I'm not sure why they have you do this first, because then you have to deal with the exposed, pre-applied thermal paste for the rest of the installation.- Installation - Cables — This was the biggest headache for me as far as installation goes. Since the cooler isn't pre-assembled, the cables all need to be hooked together and managed. They daisy-chain together, but surprisingly, there's no cable management either on the included fans or the radiator. This leaves you with a ton of extra cable which I had to zip-tie together to get the final product looking nice. Another unfortunate design choice was that the pump's RGB and power cables come out of the bottom, where the tubes are. I have no idea why this is. I don't think I've ever seen a motherboard where that would be convenient. Once I realized this, I ended up removing the already-installed bracket to route the cables up and underneath them towards the proper headers. This was the only way to make them more or less invisible, but I don't think it's the safest place to run the cables for fear of stripping them (or worse).- Installation - AM5 — This is kind of a specific thing to mention, but something that was really nice about the Arctic Liquid Freezer II I was using before was a specific offset on the mounting bracket for 7xxx chips to combat their specific hotspots. The LS520 does not offer any similar offset.- Functionality — Although it cools pretty well, the LS520's included fans are LOUD and have a pretty noticeable whirring or whistling sound when picking up speed. I'm not a stickler for noise at all, but this one gets in your ear. It's bad enough that I'm considering returning it solely based on this point.TL;DR: Great looking cooler with pretty good performance but really questionable design choices and annoying installation, as well as not so quiet operation. I honestly wouldn't really recommend it unless your case did a great job at dampening sound.
