This matches specific visual schemes while maintaining copper construction quality. Pump tops like the Eisdecke D5 add clear visibility. They suit users who want to monitor coolant flow. The lineup supports various fan mounts. You can find 40mm, 80mm, 120mm, 180mm, and 360mm options. This ensures compatibility with most custom loop designs.
Where Alphacool Fits Your Build
Alphacool targets custom loop builders who need precise form factors. The range spans from tiny 40mm and 80mm units for extreme small form factors to standard 120mm, 180mm, and 360mm radiators. Most options use copper cores for heat rejection, with finishes in black or white. You can find ARGB GPU blocks and clear acrylic pump tops for visibility. The list does not include aluminum radiators, pre-filled units, or RGB fans. If you require non-copper materials or all-in-one solutions, this brand may not suit you. Focus on their specialized copper components for tailored loop designs.

How to choose the right one
-
Match radiator size to case
Start by measuring the available space in your case for fans and radiators. Alphacool offers units in 40mm, 80mm, 120mm, 180mm, and 360mm widths. If you have a compact case, the 40mm NexXxoS XT45 Dual or the 80mm ES HPE-60 Quad provide cooling in tight spots. Standard mid-tower cases usually fit 120mm or 360mm mounts. Check the internal dimensions carefully. A 360mm Monsta radiator requires a full 360mm mount area. Selecting the wrong size means the part will not fit physically. Measure twice before buying.
-
Prioritize copper for heat transfer
Most Alphacool radiators use copper cores for superior heat rejection. Copper conducts heat faster than aluminum, which matters in custom loops. The NexXxoS XT45 series, including the 120mm and 180mm models, features full copper construction. The ES HPE-60 Quad also uses copper for maximum reliability. Check the material specification in the product data. If you need efficient cooling in a small footprint, copper is the better choice. Avoid non-copper options if thermal performance is your main goal. The weight of these parts often indicates the density of the copper used.
-
Check GPU block compatibility
GPU water blocks are model-specific. You must match the block to your exact graphics card. The Core RTX 5090 TUF block is designed solely for TUF Gaming RTX 5090 cards. It features brass fittings and a full backplate. Do not assume compatibility with other RTX 5090 models or brands. Verify the motherboard and GPU layout against the block dimensions. The block measures 9.29 inches in length. Ensure your case has enough clearance for this size. Using the wrong block can damage the GPU or fail to seal properly. Always confirm the specific card model before purchasing.
-
Select pump top for visibility
If you want to see your coolant, choose an acrylic pump top. The Eisdecke D5 Plexi Pump Top is made of clear acrylic. It fits D5 pumps and allows you to monitor coolant flow and color. This part adds visibility to your loop. It measures 3.15 inches square. Ensure your pump is a D5 model for proper fit. The clear material does not insulate heat, so pump performance remains standard. This option is ideal for builders who want to showcase their coolant choice. It adds a premium look to the top of the reservoir.
-
Consider ARGB for aesthetics
Lighting enhances the visual appeal of your custom loop. The Core RTX 5090 TUF block includes ARGB lighting. This allows you to sync colors with other RGB components. Most radiators in this list are black or white without built-in lighting. You can add separate RGB fans to complement the radiator color. The Monsta 360mm comes in black or white to match your theme. Check if your motherboard supports ARGB headers. This feature is optional but adds significant style to the build. Ensure your fans also support ARGB for a cohesive look.
Frequently asked questions

What is the smallest Alphacool radiator size available?
The smallest option is the 40mm NexXxoS XT45 Dual Radiator. It measures 3.15 inches in length and weighs 0.26 kilograms. This copper core unit is ideal for small form factor builds where space is extremely limited. It provides efficient cooling without taking up much room.
Are Alphacool radiators made of copper?
Yes, most Alphacool radiators use copper cores for heat rejection. Examples include the NexXxoS XT45, UT60, and Monsta series. Copper offers reliable durability and thermal performance. Some models, like the Eisdecke D5 pump top, use acrylic for visibility, but the heat exchangers remain copper.
Which Alphacool radiator fits a standard 360mm mount?
The NexXxoS Monsta 360mm and UT60 360mm Radiators fit standard mounts. The Monsta comes in black or white finishes. The UT60 is also available in white. Both provide triple-fan cooling capacity. The Monsta weighs 1.5 to 5.14 pounds depending on the finish.
Can I use Alphacool parts in small cases?
Yes, Alphacool offers compact options for tight spaces. The 40mm and 80mm radiators are designed for small form factors. The ES HPE-60 is an 80mm quad radiator with a small footprint. The 120mm UT60 and ST30 are also thin, making them suitable for constrained builds.
Does Alphacool make acrylic pump tops?
Yes, the Eisdecke D5 Plexi Pump Top is available. It is made from clear acrylic for coolant visibility. It fits D5 pumps and offers flexible port connectivity. The top measures 3.15 inches in width and length. It weighs 0.44 kilograms and complements custom loop aesthetics.
