Alphacool vs Thermaltake Specs
component type
You are comparing two very different liquid cooling components. Product A is an Alphacool Core GPU water block designed specifically for the GeForce RTX 5090 TUF Gaming card. It includes a backplate and ARGB lighting. Product B is a Thermaltake Pacific DIY 360mm radiator. It is a copper component with a flat tube design and stainless steel frame. One part attaches to a graphics card to transfer heat. The other part dissipates heat into the air. You cannot directly compare their functions because they serve opposite roles in a loop. One is the source, the other is the sink.
dimensions
Size matters for fitment in your case. The Alphacool block measures 9.29 inches long, 6.12 inches wide, and 1.34 inches high. It is compact and fits tightly on the GPU. The Thermaltake radiator is much larger. It measures 17.4 inches long, 6.53 inches wide, and 3.8 inches high. The radiator is over three times taller than the block. You need a case that supports a 360mm radiator mount. The GPU block requires clearance around the graphics card slot. Both items have strict spatial requirements, but the radiator demands significantly more volume.
weight
Weight affects how these parts sit in your system. The Alphacool water block weighs 3.75 pounds. This is substantial for a GPU component. It relies on the motherboard PCIe slot and bracket for support. The Thermaltake radiator weighs only 1 pound. It is lightweight due to its stainless steel frame and hollow tube design. You must consider mounting security for the heavy GPU block. The light radiator is easier to handle during installation. The difference in mass is significant, with the block being nearly four times heavier than the radiator.
material
Both brands use copper for thermal performance. The Alphacool block features a copper cooler base. It also includes high-quality brass connectors for safety and quality. The aluminum backplate covers the back of the copper. The Thermaltake radiator is built with high-density copper fins. It uses brass tanks and a controlled atmosphere soldering process. This ensures optimal thermal transfer from tubes to fins. Both products prioritize copper for heat exchange. Alphacool adds brass fittings, while Thermaltake uses a stainless steel frame for durability. Both materials are chosen for specific structural and thermal benefits.
lighting
Visual customization is a key factor for many builders. The Alphacool Core GPU water block is listed as ARGB. This allows you to sync lighting effects with your motherboard software. The Thermaltake Pacific radiator does not mention any lighting features in the data. It focuses on thermal capacity and structural durability. If you want visible RGB effects, the Alphacool block offers this capability. The Thermaltake radiator is a functional component without aesthetic lighting. You must check if your loop design includes lighting on other parts if you choose the radiator.
Which Alphacool or Thermaltake part suits you
RTX 5090 TUF owners needing direct GPU cooling
