Asus ProArt LC 420 Cooling Fan/Radiator/Water Block - 1 Pack

The Asus ProArt LC 420 is a premium all‑in‑one cooling solution designed for creators, enthusiasts, and professionals who demand quiet operation, outstanding cooling performance, and a refined aesthetic that complements high‑end workstations. Built to deliver steady, predictable thermal management for CPUs and GPUs in demanding workloads, this 420mm cooling assembly blends sophisticated engineering with a understated silhouette that fits into sleek PC builds without drawing attention away from your creative workflow. Powered by a high‑efficiency three‑phase motor and paired with Noctua IndustrialPPC fans, the LC 420 excels at moving heat away from your critical components while minimizing noise and vibration. An illuminated meter on the pump cover provides a quick visual readout of pump activity, helping you monitor the health of your cooling loop at a glance and maintain peak performance during long render sessions. This is not just about cooling—it’s about a reliable, quiet, and aesthetically refined solution that supports your work, presentation, and uptime.

  • Quiet, powerful cooling for demanding workloads: The LC 420 combines a high‑efficiency three‑phase motor with Noctua IndustrialPPC fans to deliver excellent heat dissipation while maintaining whisper‑quiet operation in typical room environments. It’s purpose‑built for sustained workloads, rendering, and creative applications where silence matters as much as performance.
  • Premium craftsmanship with a refined ProArt look: The design speaks to creators who value both form and function. The pump block and radiator assembly feature premium materials and a restrained, understated finish that complements the ProArt ecosystem and high‑end builds, ensuring a cohesive, professional appearance inside your case.
  • Real‑time monitoring at a glance: An illuminated meter on the pump cover gives you immediate insight into pump status and coolant flow, enabling quick health checks during long sessions and helping you catch potential issues before they impact your work or deadlines.
  • High‑surface area cooling with scalable compatibility: The 420‑millimeter radiator provides ample surface area for effective heat transfer, supporting overclocking headroom and stable performance in multi‑component systems. Its robust mounting and clearance options accommodate a wide range of cases, including larger chassis designed for custom cooling loops.
  • Easy integration, maintenance, and expandability: The ProArt LC 420 is designed for straightforward installation and reliable operation. The modular assembly, user‑friendly tubing routing, and dependable components minimize maintenance and simplify upgrades, making it a practical choice for builders who want premium cooling without the complexity of bespoke systems.

how to install Asus ProArt LC 420

Installing the Asus ProArt LC 420 is designed to be straightforward for builders who are comfortable with building a PC cooling loop. Begin by preparing your case and verifying that it supports a 420mm radiator. Remove the side panel, plan the radiator mounting location so that there is ample clearance for the fans, the tubing, and your memory modules. Mount the radiator to the case using the supplied screws, ensuring a stable, level installation with appropriate vibration dampening where required. Next, attach the water block to the CPU or GPU socket you intend to cool, applying thermal interface material as recommended by the manufacturer (many units come with pre‑applied paste). Secure the water block with the appropriate mounting hardware for your socket type, ensuring even pressure and a clean contact surface. Route the tubing from the radiator to the water block in a way that minimizes kinks and avoids contact with sharp edges or moving parts. Connect the fans to a suitable motherboard PWM or fan controller header to maintain dynamic cooling performance, and wire the pump to a dedicated power source or the appropriate pump header, following the manufacturer’s wiring diagram. Finally, power up the system and use the illuminated pump meter to verify operation, check for leaks in a controlled test ride, and monitor temperatures to confirm successful installation. Always follow best practices for coolant management and bleed any air from the loop before running under load.

Frequently asked questions

  • Q: Is the Asus ProArt LC 420 compatible with both Intel and AMD platforms?
    A: Yes. The LC 420 is designed to support mainstream CPU sockets common in contemporary Intel and AMD platforms. Always verify socket compatibility against the latest official product page and your motherboard specifications before purchase.
  • Q: How quiet is the LC 420 under load?
    A: The combination of a three‑phase motor and Noctua IndustrialPPC fans is engineered for low noise output, even under sustained loads. While exact audible levels depend on case acoustics and fan curve settings, this model prioritizes quiet operation as a core feature.
  • Q: Does the kit include thermal paste for the CPU/GPU?
    A: In most configurations, the water block ships with pre‑applied thermal interface material or a reusable paste placeholder, designed to speed up installation. If your kit does not include paste, you can apply a reputable thermal paste through the standard method recommended by the water block manufacturer.
  • Q: Can I upgrade to a multi‑radiator loop or add more radiators later?
    A: The LC 420 is designed as a complete 420mm solution. While you can integrate additional cooling components in a custom loop, the LC 420 unit itself is a self‑contained assembly. For expansion, check compatibility with your case and other cooling modules and consider consulting professional guidance for a multi‑loop setup.
  • Q: What maintenance is required?
    A: All sealed AIO cooling solutions require minimal maintenance. Periodically inspect tubing and fittings for signs of wear or leaks, ensure the pump is functioning normally (as indicated by the illuminated meter), and replace coolant if you notice changes in performance or transfer efficiency. Follow the manufacturer’s safety and service guidelines for best results.

Awful.
Color: Black, Size: 22"- 4 Panel
Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

Great Dividers
Size: 6 Panel-120"W, Color: Beige
Love these!! Many uses. Simple, nice looking, sturdy overall. Well made. Bought to divide the unsightly storage area from the calm rest area in the basement. Also, these worked well for our garage party where the dividers let light and air in, though blocked the view of our party area from the cars driving by.

Just what I needed
Size: 4 Panel-136"W, Color: Black
I have a one bedroom apt and my son stays with me half the time. He has an air mattress in the living room until I can afford a 2 bedroom. But he’s in his early teens and needs privacy. I bought this after looking online at may of these. I’m so glad I went with this one. It covers his air mattress 3/4 of the way around and now he has his own little nook. I also gave him some led lamps and he might it like his own little nightclub. He LOVES it. And now he’s excited to be in his space. The quality is so good and there’s no see through, no gaps, it’s perfect.

Instructions could be clearer, but assembles well and is sturdy
Size: 3 Panel-102"W, Color: Black
The only reason for the lack of a star is the iffy instructions. There are a few different washers and the instructions could make the difference a LOT easier to understand and thereby reduce the need to re-do things. Other than that, the panels were easy to assemble and the parts fit well together. I was able to disassemble the screens and store them for a future use, which is nice. One caution - the feet that make the panels stand up will likely be a trip hazard, so be sure to plan the location for this device carefully.
