Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator (14246)

The Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator is a 420 mm radiator for three 140 mm fans, 45 mm thick, for a water cooling loop. It is the X-Flow type, with the inlet on one chamber and the outlet on the opposite one. The fan threads are M3 and the connections are G1/4.

Properties

• Fans: 3 x 140 mm, M3 fan thread
• Thickness: 45 mm (Alphacool's 39 - 49mm class)
• Ports: G1/4
• Material: Copper cooling channels and slats, steel housing
• Fins per inch: 16
• Cooling channels: 28

Full copper

Alphacool says the new NexXxoS radiators are the first to truly deserve the "Full copper" attribute. Not only the fins and channels but all main parts are made from copper, the chambers also. The channel heads are copper too. In Alphacool's words this brings an improvement in performance where other radiators are left without a chance.

X-Flow

In structure, Alphacool explains, the X-Flow Radiators differentiate materially from the standard radiators, because they are designed for high flow rates. A beveled copper chamber sits on both sides, and the two have an identical structure. Water enters one chamber and goes jetting through all available channels at the same time to the other chamber, which is where it then leaves the radiator.

Ports and mounting

Alphacool's research and development department focused on versatile and easy mounting as one of the main points. The aim: each copper chamber offers possibilities for fitting installation, so that less angled fittings are needed, improving flow rates and offering more mounting possibilities. The connections are G1/4.

What the loop needs

Two G1/4 connections are used, one as inlet and one as outlet, so the radiator takes two fittings. Four screw plugs are in the box. It holds three 140 mm fans on its M3 threads, and mounting hardware is in the box.

The next thickness down in this fan size and type is the NexXxoS ST30 Full Copper X-Flow 420mm Radiator.

Notes

• Alphacool asks that the radiator be used only in conjunction with clear, transparent water cooling fluids. It warns that the particles and additives in pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses. That can also result in voiding the manufacturer's warranty.
