Single-tower cooler for mainstream builds

The Montech NX400 ARGB (W) is a single-tower CPU air cooler built around 4 advanced heat pipes and a 52-fin heat sink. A 120 mm fluid-dynamic-bearing fan spins at up to 2000 RPM, pushing 85.09 CFM at 34.17 dBA. The 28 mm thick fan, white finish, ARGB lighting and polished top cover suit mainstream Intel and AMD platforms.

Upgrade from stock or slim coolers when noise

This cooler replaces basic box coolers or low-profile towers that hit thermal limits under sustained loads. The thicker static-pressure fan and vacuum-enhanced heat pipes move heat faster without a larger footprint. The jump is worth it when your current cooler throttles the CPU or runs loud enough to be distracting in a quiet room.

Check socket brackets.

Verify the box includes the correct mounting hardware for your specific socket — LGA 115x, 1200, 1700, 1851, AM4 or AM5. Confirm the 120 mm fan height and tower width leave room for tall memory modules and the top PCIe slot. Ensure your motherboard has a 5 V 3-pin ARGB header to control the lighting.

Questions about this item

How much clearance does the 28 mm thick fan and single-tower heatsink need above the CPU socket?

The cooler stands 120 mm tall with a 28 mm thick fan, so allow at least that much vertical space inside your case above the socket.

Which mounting brackets do I use for an LGA 1700 or AM5 socket, and what is the common installation mistake?

Use the supplied interchangeable brackets for LGA 1700 or AM5; the step most people miss is tightening the back-plate screws evenly before seating the heatsink.

When should I clean the 52 fins and fluid-dynamic-bearing fan, and how?

Clean the 52 fins and fan blades with compressed air every 6–12 months; the fluid-dynamic bearing is sealed and does not need lubrication.
