Alphacool NexXxos Monsta Radiator 420, 140mm x 3, Triple Fan, Black

The Alphacool NexXxoS Monsta 420mm Radiator is a 420 mm radiator for three 140 mm fans. It measures 468 x 144 x 86 mm, which Alphacool files in its 69 - 100mm thickness class, and it has seven G1/4 connections and M3 fan threads.

Properties

• Fans: 3 x 140 mm, M3 fan thread
• Size (L x W x H): 468 x 144 x 86 mm
• Ports: 7x G1/4
• Material: Copper cooling channels and slats, steel housing
• Color: Black

Full copper

Alphacool says the new NexXxoS radiators are the first to truly deserve the "Full copper" attribute. All main parts are made from copper: not only the fins and channels, but the chambers also. In Alphacool's account this brings an improvement in performance where other radiators are left without a chance. It adds that the material already gives an advantage over the competition and that the inner structure is up to par with it. Separated chambers give the coolant a clear direction, allowing high flow rates which improve the performance of the whole cooling loop. The chambers on the heat exchanger are flat, and thanks to the reduced overall length they increase mounting flexibility.

Ports and mounting

Versatile and easy mounting is one of the main points on which the research and development department at Alphacool focused. The chamber offers three possibilities for fitting installation on both inlet and outlet (not on the NexXxoS ST30). With that choice, less angled fittings are needed, improving flow rates and offering more mounting possibilities. Hence the radiator can even be installed in tight enclosures, where internal installation is otherwise not a possibility. A G1/4 screw plug, found on all UT60 and NexXxoS Monsta radiators, allows easy de-aeration and hassle-free vertical installation of the heat exchanger. Its threaded opening can even be used for filling, e.g. in combination with a Fillport.

What the loop needs

The radiator has seven G1/4 connection threads: three on the inlet, three on the outlet and the de-aeration port. A loop uses two of them, so it takes two fittings. The five plugs in the box close the connections you do not use and the de-aeration opening. It takes three 140 mm fans, and the box holds twelve M3x30mm and twelve M3x35mm screws for them.

The next thickness down in this fan size is the NexXxoS UT60 Full Copper 420mm Radiator.
