Seems like ASUS is fully committed to giving its entire product families their own AIO with the ProArt series receiving its own AIO CPU liquid cooler but not just any cooler. I’ve always admired ASUS for the thought that goes into the ProArt product family like the well thought-of layout of their motherboards or the tight dimensions of their GPUs to fit multiple cards and leaving space for another one. The same thought has gone on for the ProArt line’s first cooler and its the ASUS ProArt LC 420. Yes, a 420mm cooler.


The ProArt line has been a minimalist and subdued brand and the ProArt LC420 definitely fits that mantra with 140mm fans proving to be quieter at full-loads and the lack of RGB is certainly on-brand.
Just like the ROG Ryujin, the LC 420 features NOCTUA chromax fans but uses larger 140mm fans versus 120mm on the RYUJIN. This cooler is ASUS’ first 420mm AIO cooler as well so it has no performance counterpart but the cooler itself could be a whitelabel cooler with an off-the-shelf design, tweaked to ASUS standards.
Showed together with the ProArt LC 420 is the new ProArt RTX 4080 and a ProArt X670E motherboard on a custom chassis made specifically for this COMPUTEX. The case is not a WIP ProArt case but if interest is high, ASUS could easily make one.
