Ultra-Quiet 240 mm AIO

The Montech HyperFlow Silent 240 White is an all-in-one liquid CPU cooler built for users who prioritise silent operation. It targets builders assembling workstations or gaming rigs where audible fan noise must stay at a minimum. The ARGB-free design suits minimalist, professional aesthetics. It is not for buyers who want addressable lighting or a larger 360 mm radiator for extreme overclocking headroom.

3100 RPM pump with 27 mm radiator

The cooler uses a 3100 RPM pump paired with a 27 mm thick radiator featuring a 20 FPI fin stack. Three Metal PRO 12 Silent fans spin at up to 2200 RPM while producing only 24.8 dBA each. Combined system noise is rated at 45.18 dBA. This capacity handles high-performance CPUs under sustained loads, but thermal limits will appear before a thicker 360 mm unit reaches its ceiling.

Pre-installed fans and broad socket support

The unit ships with fans already mounted and thermal paste pre-applied on the cold plate, reducing assembly steps. It supports current Intel and AMD sockets for straightforward integration into most modern builds. The 240 mm radiator requires compatible case mounting points. The six-year warranty and leakage protection add long-term confidence without extra configuration.

Questions about this item

Will the 240 mm radiator and 120 mm fans fit in a case designed for older 240 mm AIOs?

The 27 mm slim radiator and 120 mm fans match the standard 240 mm mounting pattern, so it fits cases built for earlier 240 mm coolers.

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

Connect the pump header to the motherboard and monitor RPM in BIOS or fan-control software; it should read 3100 RPM ±10 %.

Are the three Metal PRO 12 Silent fans and thermal paste already on the unit, or do I need to buy them separately?

The three 120 mm fans come pre-installed and thermal paste is pre-applied on the cold plate, so no extra parts are required.
