Single-tower air cooler with 28 mm fan

The Montech NX400 ARGB (B) is a single-tower CPU air cooler built around four heat pipes and a 52-fin heat sink. It targets builders who want strong thermal performance in a compact footprint and who value addressable RGB lighting on the fan.

Installation uses interchangeable brackets

The package includes interchangeable mounting brackets that cover Intel LGA 115X, 1200, 1700 and 1851 as well as AMD AM4 and AM5. The 28 mm thick fan attaches with vibration-dampening corner pads; the main issue installers report is limited clearance for tall memory modules on some motherboards.

Check CPU socket and RAM clearance

Verify that your motherboard uses one of the listed sockets before ordering. Measure the distance from the CPU socket to the first DIMM slot and to any nearby VRM heatsinks to ensure the 120 mm fan and heat sink will not interfere with memory or power components.
