ASUS ProArt LC 420mm AMD/Intel Liquid CPU Cooler

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.

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.

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

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.

Performance and reliability on the actual cooling side of this are excellent — temps run low and consistent, the pump and radiator combo does exactly what a 420mm AIO from ASUS should do, and under sustained load it never gave a reason to doubt it. Installation itself went smoothly at first, standard mounting, nothing unusual to fight through getting the block seated. The problem is entirely in the small hardware: the mounting screws are shockingly fragile and break far too easily, way beyond what should be normal for a part you're only supposed to touch once or twice during install. Once one snapped, the real trouble started — these aren't a standard hardware store screw, they're specific to this cooler, and finding a replacement has been next to impossible. Ended up having to pull the whole unit back off just to dig for a serial number to even start a support request for something this small, which is an absurd amount of effort for a 20-cent part — would have gladly paid 10 dollars just to get the right screw shipped and be done with it. On top of that, support apparently wants the original box before they'll help at all, so if you've already broken it down like most people do after unboxing a cooler, you're stuck with functionally no support path. Value for money takes a real hit here, not because the cooler underperforms, because it doesn't, but because a tiny piece of hardware shouldn't be the thing standing between you and a fully mounted cooler with zero support options if the box is gone. Mounting overall would be a non-issue if the screws weren't this brittle. If the screw quality and the box requirement for support get fixed, this is an easy 5 stars — as it stands, the cooling itself earns the score, the hardware and support process drag it down. This was Puchased in combination with the case also pro art. Pretty disappointed my last case was so solid.

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

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.
