ASUSProArt LC 360 all-in-one AIO CPU liquid cooler AMD AM4 AM5 & Intel LGA 1700, 1200, 115X support, with illuminated system status meter and three matte black Alphacool Apex Stealth Metal Power fans

Thermals are great with my 9800x3d, never above 60 degrees. No noticeable pump sounds (been a few months). Complements ProArt x870e and PA602 case very well. I would really only suggest this cooler if you had other ProArt components in your build. Otherwise, I’d just go with a cheaper AIO. I did swap out the 3 noctua 140mm industrial fans with 3 Noctua A14 140 PWMs fans. Not necessary, just wanted to min/max fan noise. But if you were wondering how easy they are to swap out, I had no issues.One suggestion. This product was not showing up on the newest version of Asus Armoury Crate. I believe it was recently updated at the time and I read stories online of how Armoury Crate is a mess after an update. If it doesn’t show up for you, download the previous version of Armoury Crate. That’s what worked for me.

So, I've been using the ASUS ProArt LC 420 AIO cooler with my i9 14900K, and it’s been rock solid. Even when I'm pushing the system hard with video rendering and gaming, the temps stay well under control—rarely going over 85°C.One thing I like is that it doesn’t go overboard on flashy nonsense. It’s just a clean, all-black cooler that fits in with my build. No RGB, no distractions—just does its job quietly in the background. Speaking of quiet, it’s impressively low-noise most of the time. It ramps up a bit when the system’s under load, but it’s still quieter than a lot of other coolers I’ve used before.Installation was pretty straightforward, though you’ll want to make sure you’ve got a big enough case since it’s a 420mm radiator. If you’ve got the room, it’s no hassle at all.All in all, it’s a no-nonsense cooler that handles the heat of a 14900K really well. If you’re after reliable cooling without all the RGB craziness, I’d say give it a shot. It just works, and that’s exactly what I need it to do

No complaints, the Alphacool fans on this are actually better than the Noctua fans on the 420. Don't understand why someone would be upset with that.Best fans I've ever had in a case, I actually went and bought more of the 120mm Alphacool fans in some other colors.

-In my PA602 I cannot align these holes to screw in and fix it. unacceptable issue-Always has noise near the radiatorNothing else I can say. It is already in my 602 case and I will not waste my time to uninstall and return it. PA’s quality doesn’t match their reputation.

The best cpu cooler on the market.

Product came with 2 of the 3 fans defective. They make a mechanical whirring sound that is the loudest noise in the room. One of the 3 fan is working fine. Upon contacting Asus to ask for the 2 fans to be replaced they told me to return the entire water cooler to Amazon and get a replacement. I said I didn't want to because I would have to buy new thermal paste and have the computer system down while waiting. I was then told I would have to send Asus the whole water cooler. They would not replace just the 2 fans that are defective. I've been building computers for 25 years and have had to do returns once in a while. I've never had to return an entire item like this where the defective parts are easily separated AND actually come separated (you have to assemble it yourself). The product itself keeps the CPU cool. I wish the tubes were about 6" longer, but most AIO water coolers have the same length. If I return the whole water cooler I would have to buy new thermal paste and not use the computer until a replacement was received. I paid a LOT of money for this water cooler. I expected a LOT more from tech support for such a high end item.

Great to pair with the ProArt case. Love the clean LED on the block. No numbers no fuss.

Open the product today to find out that the product was defective as you can see from the picture.I will update this reviewThe return of the device went extremely smooth with no issues. I would have really preferred to have used this in my build.
