Alphacool NexXxoS XT45 Full Copper X-Flow 280mm Radiator, 140mm, G1/4, 45mm (14245)

The Alphacool NexXxoS XT45 Full Copper X-Flow 280mm Radiator is a 280 mm radiator for two 140 mm fans, 45 mm thick. It is the X-Flow type: the water enters the copper chamber on one side and leaves from the chamber on the other. The fan threads are M3 and the connections are G1/4.

Properties

• Fans: 2x 140 mm, M3 fan thread
• Thickness: 45 mm
• Ports: G1/4
• Material: Copper cooling channels and slats, steel housing
• Fins per inch: 16

Full copper

Alphacool calls the new NexXxoS radiators the first to truly deserve the "Full copper" attribute. Not only the fins and channels are copper but the chambers also, so all main parts are made from it. Alphacool says this brings an improvement in performance where other radiators are left without a chance.

X-Flow

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

Connections and mounting

Versatile and easy mounting is one of the main points on which the research and development department at Alphacool focused. 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.

Fans and screws

Fans and radiator grills go on M3 threads, and Alphacool describes even their mounting and installation as easy and versatile with these radiators. M3 is standard in the radiator sector, so M3 screws are available in all lengths at an affordable price. A screw that is too long is covered as well: the dreaded insertion of a screw too far into the radiator does not result in expensive damage. Unlike other radiators, Alphacool says, the series is equipped with an internal protective ledge which stops the screw before it damages the fins.

What the loop needs

The loop uses two G1/4 connections, one as inlet and one as outlet, so the radiator takes two fittings. It holds two 140 mm fans, and mounting hardware is in the box.

The thinner radiator in this fan size and type is the NexXxoS ST30 Full Copper X-Flow 280mm Radiator.

Notes

• Alphacool's note on application: use the radiator only in conjunction with clear, transparent water cooling fluids. The particles and additives in pastel liquids can clog and permanently damage water cooling products such as radiators, pumps, coolers and hoses. Alphacool adds that this can result in voiding the manufacturer's warranty as well.
