Three Noctua NF-A14 industrialPPC-2000 PWM 140mm fans deliver high airflow and static pressure, helping the cooler move heat efficiently through the large radiator.

Frequently Asked Questions

Does the ASUS ProArt LC 420 support Intel LGA1851 and AMD AM5?
Yes. ASUS lists support for Intel LGA 1851, LGA 1700, LGA 1200 and LGA 115x, plus AMD AM5 and AM4 sockets.
What makes this cooler different from standard 360mm AIO coolers?
It uses a larger 420mm radiator, three 140mm Noctua industrialPPC fans, 450mm tubing and an illuminated system-status meter, giving it stronger cooling capacity and a more refined ProArt look.
Will it fit every PC case?
No. The case must support a 420mm radiator with enough clearance for the 456 × 140 × 30 mm radiator, 140mm fans, tubing route and CPU socket area.
Singular Expert Insight
Choose the ASUS ProArt LC 420 if you want a premium 420mm AIO cooler for a creator or workstation build where strong cooling, Noctua fans and understated design matter. If your case only supports 240mm or 360mm radiators, choose a smaller AIO instead.

Buyer’s Guide

Buy it if
You need a premium 420mm AIO CPU cooler with Noctua 140mm PWM fans, copper CPU plate, illuminated system meter and support for modern Intel and AMD sockets.
Skip it if
Your case cannot fit a 420mm radiator, you want RGB gaming styling, you need a budget cooler, or a 240mm/360mm AIO is enough for your CPU.
Also consider
Consider a ROG Ryuo or Ryujin cooler if you prefer a gaming-focused display and RGB style, or a 360mm AIO if your case has more limited radiator support.
