White 240 mm AIO for Intel and AMD builds

This Montech LightFlow ARGB 240 White is a 240 mm all-in-one liquid cooler designed for current Intel LGA 1700 and LGA 1851 sockets as well as AMD AM4 and AM5 platforms. It targets enthusiasts who want a white-themed build with addressable RGB lighting and a pump that runs at 3100 RPM for strong circulation.

Aluminium radiator, fluid-dynamic fans.

The 277 mm aluminium radiator fits two 120 mm slots and ships with fans pre-installed on fluid-dynamic bearings that spin between 600 and 2000 RPM. Each fan moves up to 78.73 CFM at 2.39 mmH₂O static pressure while producing 34.3 dBA; the pump itself runs at 28 dBA. Both PWM 12 V 4-pin and 5 V 3-pin ARGB connectors are used for control and lighting.

Verify case clearance

Measure that your chassis can accommodate a 277 mm long radiator with two 120 mm fan positions and that there is room for the 66.9 mm diameter by 56.0 mm high pump block. Confirm the motherboard provides a 5 V 3-pin ARGB header and a standard PWM fan header for the pump and fans. The cooler supports Intel 1700 and 1851 plus AMD AM4 and AM5 sockets only.

Questions about this item

What socket standard does the 240 mm radiator block support and what CPU generations does that cover?

The block fits Intel LGA 1700 and 1851 plus AMD AM4 and AM5 sockets, covering current mainstream desktop platforms from both vendors.

What are the radiator dimensions and how many fan slots must the case provide?

The radiator measures 277 mm in length and requires two 120 mm fan mounting positions in the chassis.

How is the pump powered and which header do installers often connect to the wrong pin count?

The pump runs at 3100 RPM from a PWM 12 V 4-pin header; the separate ARGB lighting uses a 5 V 3-pin header that is frequently plugged into a 12 V 4-pin RGB connector by mistake.
