What this AIO cools

The Thermaltake MAGFloe 420 Ultra is an all-in-one liquid cooler built for modern desktop CPUs. It supports Intel sockets from LGA 1150 through LGA 1851 and AMD sockets from AM2 through AM5. The copper cold plate transfers heat into a 456 x 139 x 27 mm aluminium radiator. Three 140 mm fans mount on the radiator for push or pull airflow.

Capacity and headroom

Each fan runs between 500 and 2000 RPM under PWM control. Standard blades move 81.6 CFM at 34.5 dB-A while generating 3.17 mm of static pressure. Reverse blades move 79.3 CFM at 38.8 dB-A with 2.73 mm of static pressure. The 460 mm rubber tubes set the maximum distance between the pump block and radiator mounting points. Radiator thickness of 27 mm fits most mid-tower cases.

Build quality and daily use

A 3.95 inch square LCD on the pump block displays custom images, video or system data. MagForce 2.0 magnetic fan-to-fan links and daisy-chain cables simplify wiring and prevent signal drop-out from misalignment. Fan blades are swappable between standard and reverse orientation. ARGB lighting is integrated. The white finish matches light-themed builds.

Questions about this item

Will the 420 mm radiator and 460 mm tubes reach my existing LGA 1700 motherboard in a standard ATX case?

The radiator measures 456 x 139 x 27 mm and tubes are 460 mm long; it supports LGA 1700 plus LGA 1851, 1200, 1150, 1151, 1155, 1156, 2011, 2011-3, 2066 and AMD AM5, AM4, AM3+, AM3, AM2+, AM2, FM2, FM1 sockets.

How can I confirm the 3.95" LCD and three 140 mm fans are running correctly after installation?

The LCD should display images, video or live system data, and each fan should spin between 500 and 2000 RPM; standard blades move 81.6 CFM at 34.5 dB-A, reverse blades 79.3 CFM at 38.8 dB-A.

What comes in the box and what must I buy separately for the magnetic daisy-chain and swappable blades?

The box includes the 420 mm aluminium radiator, copper cold plate, pump block with 3.95" LCD, three 140 mm SWAFAN EX fans with standard and reverse blades, magnetic daisy-chain cables and mounting hardware for all listed sockets; no extra parts are required.
