It is a straightforward component for those who prioritize raw thermal performance over aesthetic gimmicks. The specifications are clear and practical for builders who know what they need.
What stands out
- Full copper construction for maximum thermal conductivity
- 360mm size fits three 120mm fans
- 16.3-inch width requires compatible case mounting
- 1.77-inch thickness allows standard fan placement
- Black finish for clean aesthetic integration
Who it fits
Good fit for
You should buy this if you have a mid-tower or full-tower case with a top or front mount that supports 360mm radiators. The full copper core suits users who want reliable heat dissipation without relying on aluminum alloys. If you prefer a standard 1.77-inch thickness, this fits most standard fan profiles. It is ideal for enthusiasts building a high-performance loop who value material quality over flashy features. The dimensions are standard, making it easy to plan your build layout.
Who should skip it
You should skip this if your case only supports 240mm radiators or has limited clearance for thicker units. The 16.3-inch width will not fit in many compact or small-form-factor cases. If you prefer aluminum cores for lighter weight, this copper model at 2.39 pounds is heavier. Users looking for pre-filled loops or integrated pumps should look elsewhere, as this is a standalone radiator. Check your specific case specifications before purchasing to ensure physical compatibility.
Verdict: This radiator offers solid copper construction in a standard 360mm form factor. It fits well in cases that support its width and thickness.
Key specs explained
Radiator Size: 360mm
This dimension refers to the total length of the heat exchanger. You need a case or chassis that can accommodate three 120mm fans in a row. This size is standard for high-performance custom loops. It balances cooling capacity with physical space constraints. You should check your case specifications to ensure the mounting area is clear. Larger sizes offer more surface area for heat dissipation.
Material: Copper
Copper is the core construction material for this radiator. It offers superior thermal conductivity compared to aluminum. This means the metal transfers heat from the coolant to the fins more efficiently. You benefit from better temperature drops under heavy loads. This material choice targets users who prioritize maximum cooling performance over weight or cost savings in their liquid cooling builds.
Width: 16.3 inches
This measurement defines the horizontal span of the unit. It corresponds to the space required for mounting three fans side by side. You must verify that your computer case has enough clearance in the front, top, or rear. This width is a standard industry metric for 360mm radiators. Ensuring your case meets this dimension is critical for proper installation and airflow management.
Height: 1.77 inches
This thickness indicates the depth of the core and fins. A 1.77-inch profile is typical for standard density radiators. It allows for good airflow while maintaining structural rigidity. You should ensure your fans fit within this depth without obstructing other components. This height is common in many mid-tower and full-tower cases. It offers a balance between heat exchange surface and air resistance.
Design and build analysis
The Alphacool NexXxoS XT45 X-Flow 360mm radiator is built with a full copper core. According to the listing, this material choice prioritizes thermal conductivity over corrosion resistance or weight savings. Copper transfers heat efficiently, which is essential for high-density loops. The exterior features a black finish. This color is purely aesthetic and does not affect performance. It allows the radiator to blend into dark-themed builds without drawing attention to the hardware itself.
You receive a unit that measures 16.3 inches in width, 4.88 inches in length, and 1.77 inches in height. This specific height is standard for single-pass designs. It fits most mid-tower and full-tower cases that support three 120mm fans. The weight is listed at 2.39 pounds. This mass comes from the solid copper construction. You need sturdy mounting points to support this weight without sagging. The model number 1011662 identifies this specific black variant.
This design targets users who value material quality and proven heat exchange mechanics. The straightforward layout lacks complex internal structures or integrated controllers. You connect it directly to your loop tubing. The build is utilitarian. It relies on the inherent properties of copper and the surface area of the 360mm form factor to dissipate heat. There are no visible electronics or displays. The focus remains entirely on the physical exchange of thermal energy.
Setup and everyday use
Installing this Alphacool NexXxoS XT45 X-Flow 360mm radiator requires careful planning around its physical dimensions. The unit measures 16.3 inches wide, 1.77 inches high, and 4.88 inches deep. You must verify that your computer case has sufficient clearance for this width and depth. The 1.77-inch height is standard for three 120mm fans, but you need to check for interference with RAM or CPU coolers. The black finish matches many modern builds, but the copper core remains internal. This construction means you rely on the external tubes and fittings for material compatibility. You should use fittings compatible with copper to prevent galvanic corrosion. The 2.39-pound weight suggests it is sturdy but heavy. You need secure mounting points to support this mass during operation. The X-Flow design implies a specific airflow path. You should align your fans to push air through the core in the intended direction. This orientation matters for thermal performance. Daily use involves monitoring coolant temperatures. The full copper core provides efficient heat transfer. You benefit from stable thermal performance under load. However, the material choice means you must maintain proper coolant chemistry. Additives designed for copper systems help preserve the core. The listing does not mention included fans. You need to source compatible 120mm fans separately. The 360mm size allows for high airflow potential. You get cooling capacity proportional to the surface area. Regular maintenance involves checking for leaks and ensuring fan operation. The simplicity of the design reduces failure points. You get a reliable heat exchanger if installed correctly. The lack of complex features means fewer things can go wrong. Focus on proper sealing and airflow direction for best results.
Before you buy this radiator
You need to pair this full copper radiator with compatible tubing and fittings. The XT45 uses standard 3/8-inch ID ports, so verify your hardware matches. Copper cores require proper coolant selection to prevent corrosion. You should use distilled water and a reputable inhibitor. Do not mix different coolant types. This unit is heavier than aluminum alternatives, so ensure your case mounts are sturdy. It fits best in custom loops where maximum thermal performance is the priority. If you prefer maintenance-free AIOs, this might not be for you. You must manage fluid levels and check for leaks regularly. Compare this against the 480mm and 420mm variants if you have more space. The 360mm size offers a balance for most mid-tower cases. Check your fan depth clearance as well, since the 1.77-inch thickness can limit airflow if fans are too thick. Proper planning ensures reliable operation.
Check before you buy
- Verify your case supports 360mm radiator mounting points.
- Ensure 3/8-inch ID tubing matches your fittings.
- Check fan thickness fits within 1.77-inch clearance.
- Confirm you have space for copper weight.
