ASUS ProArt LC 420 All-in-one CPU Liquid Cooler with Illuminated System Status Meter and Three Noctua NF-A14 industrialPPC-2000 PWM 140mm Radiator Fans, 6 Year Warranty

This thing is vary big, was hard to get in, but looks super nice, you can't hear it at all as I have the fans at like 920rpm, you can start to hear the fans at like 1000rpm and this is with the glass off, I have it in the lian li Lamborghini evo rgb case, im running this with the i7 12700k and it is keeping temps well below 80 all the time, packaging is vary nice, fans are super hard to get on the radiator but it worked, it is 100% worth it over any air cooler as its much quieter, can cool anything, and makes your pc much more spacious.

The best liquid cooler I've owned. Asus ProArt 420 is 10000000x/10 compare to my previous Corsair H150i Capellix LCD XT 360mm AIO with Lian Li SL Infinity which was about 9/10. Temps are about 20C cooler on average. Worth the upgrade, and totally stylish.

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

My recommendation would be to get the proart x870e-creator motherboard and pro art case that come with it. Absolute monster of a cooling machine.

Excellent AIO to pair with my Pro Art case. I love the triple 140mm sized fans while the CPU temps remain low and stable. The price could be a bit better but overall I'm very pleased with the purchase so far.

Can cool my 14900k really damn good

Easy to install, fits well in my PA602, gives a refreshing look to my old parts

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.

Bajen el instructivo en línea, el que trae es muy pequeño y es difícil entender cómo debe acomodarse correctamente si se instala en un gabinete proart. Ya que le entiendes es sumamente sencillo y funciona a la perfección y es impresionante lo silencioso que es. Eso si, es muy sobrio, pero lo compensa los tres ventiladores industriales imbatibles que trae.

The ASUS ProArt LC 420 AIO Liquid Cooler fits properly in the ASUS ProArt PA602 case. You can ignore the negative reviews regarding compatibility-as long as the installation instructions are followed correctly, it installs without issues. The much thicker ARCTIC Liquid Freezer III 420 also fits in the PA602. You just need to trim two of the plastic guide rails on the top mesh for proper clearance. Great AIO 420 water cooler, and it matches perfectly with the ASUS ProArt PA602- including the PA602 wood‑edition case.

Alors Installation parfaite dans un boitier Asus Pro Art PA-602. Il refroidit très bien le processeur (Amd Ryzen 9800X3D), je ne monte pas à plus de 55° en charge. Pourquoi 2 étoiles seulement ? A cause des ventilateurs, ce sont bien des Noctua, cependant, ces ventilateurs n'ont rien à voir avec les fameux a14x25, ce sont d'autres ventilateurs de type "industriels" et qui sont donc bas de gamme. Les ventilateurs ont un coil whine terrible, impossible à régler, aucune solution de la part d'Asus à part "c'est un bruit normal". Bref, je vais remplacer les ventilateurs par de VRAIS ventilateurs Noctua

Works well. Understated lighting (a simple, single colour light scale). Would be nice if you could change the colour however but there's no option to do that.
