240 mm AIO for mainstream CPUs

The Montech LightFlow ARGB 240 Black is a closed-loop liquid cooler built around a 277 mm aluminium radiator and two 120 mm ARGB fans. It targets builders who want quiet, reliable thermal control for modern Intel and AMD desktop sockets without custom-loop complexity. The unit ships with fans pre-installed to shorten assembly time.

3100 RPM pump and 78.73 CFM airflow headroom

The pump runs at 3100 RPM ±10 % and produces 28 dBA, while the FDB fans span 600–2000 RPM ±10 % to deliver up to 78.73 CFM at 34.3 dBA and 2.39 mmH₂O static pressure. This combination handles typical gaming and productivity loads on supported sockets; sustained heavy all-core workloads may push the 240 mm radiator surface toward its thermal limit.

Intel 1700 and 1851 plus AMD AM4 and AM5 mounting

The cold plate includes brackets for Intel LGA 1700 and 1851 as well as AMD AM4 and AM5, covering current mainstream platforms. PWM 12 V 4-pin and 5 V 3-pin ARGB connectors integrate with standard motherboard headers for speed and lighting control. The compact 66.9 mm diameter by 56.0 mm high pump block leaves clearance for tall memory modules in most chassis.

Questions about this item

Will the 277 mm radiator fit in a case that only lists 240 mm support?

The radiator measures 277 mm overall; cases rated for 240 mm are designed for 277 mm units, so it will fit.

How do I confirm the pump is running at its rated 3100 RPM after installation?

Connect the pump header to a PWM fan header, then read the RPM in BIOS or monitoring software; it should report around 3100 RPM ±10 %.

Are the two 120 mm ARGB fans already mounted on the radiator, or must I buy them separately?

Two 120 mm ARGB fans come pre-installed on the radiator with FDB bearings and PWM/ARGB cables included.
