Featuring copper chambers, fins, and channels, it ensures maximum cooling efficiency and durability. Its innovative dual-chamber design allows simultaneous water flow through all channels, reducing tubing complexity and enhancing performance. With 4 G1/4" ports, standard M3 mounting threads with protective edges, and optimized fin spacing, it offers versatile installation and quiet operation, making it a top choice for professional-grade water cooling setups. ## Description 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. 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. Technical data: Cooling channels: Copper; Color: black; Fan thread: M3; Slats: Copper; Thickness: 39 - 49mm; Connection: G1/4; Fan size: 140mm; Number of fans: 3; Housing: Steel; Manufacturer: Alphacool; Fins per inch: 16; Pressure tested: 0.8 bar; Quantity of cooling channels: 28. 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. In the box: 1x Radiator; 4x screw plug; Mounting Hardware. ## Features - 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.

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. - In the box: 1x Radiator; 4x screw plug; Mounting Hardware ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HQ8KZ1M | | Best Sellers Rank | #762 in Water Cooling Systems | | Brand | Alphacool | | Brand Name | Alphacool | | CPU Socket | Nicht unterstützt | | Cooler Heatsink Material | Copper | | Customer Reviews | 4.6 out of 5 stars 103 Reviews | | Global Trade Identification Number | 04250197142465 | | Included Components | 1x Radiator, 4x screw plug, Mounting Hardware | | Item Dimensions L x W x H | 18.43"L x 1.77"W x 5.67"H | | Item Highlight | Full Copper Construction, X-Flow Design for High Flow Rates, 45mm Thickness, Three Fitting Installation Possibilities | | Item Weight | 1697 g | | Manufacturer | Alphacool | | Model | 14246 | | Number of Items | 1 | | Part Number | 14246 | | Product Dimensions | 18.43"L x 1.77"W x 5.67"H | | Unit Count | 1 Count | | Warranty Description | One year manufacturer | ## Product Details - **Brand:** Alphacool - **Cooler Heatsink Material:** Copper - **Item Weight:** 1697 g - **Product Dimensions:** 18.43"L x 1.77"W x 5.67"H - **Unit Count:** 1 Count ## Images ![Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator (14246) - Image 1](https://m.media-amazon.com/images/I/61OaNlKIbTL.jpg) ![Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator (14246) - Image 2](https://m.media-amazon.com/images/I/51GxBMdNM-L.jpg) ![Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator (14246) - Image 3](https://m.media-amazon.com/images/I/61ql7nLrZOL.jpg) ![Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator (14246) - Image 4](https://m.media-amazon.com/images/I/519YbH468BL.jpg) ![Alphacool NexXxoS XT45 Full Copper X-Flow 420mm Radiator (14246) - Image 5](https://m.media-amazon.com/images/I/61hYVT7+ebL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Alphacool NexXxos XT45 Full Copper X-Flow Radiator, 420mm, Triple Fan, Black - Alphacool NexXxos UT60 Full Copper Radiator 420, 140mm x 3, Triple Fan, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/66100123-alphacool-nexxxos-xt45-full-copper-x-flow-420mm-radiator-14246](https://www.desertcart.gr/products/66100123-alphacool-nexxxos-xt45-full-copper-x-flow-420mm-radiator-14246) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-24*
