Unique-Bargains Aluminum Water Cooling Block 40x80x12mm Polished Heatsink Nozzle Upward

Polished Aluminum Water Block

This 40 x 80 x 12 mm aluminum cooling block is built for custom liquid-cooling loops on CPUs, graphics cards, motherboards or semiconductor devices. Its extruded M-shaped internal channel and brazed construction provide a continuous flow path without internal seams. The polished surface finish reduces corrosion risk and simplifies thermal-paste application. The block ships new and ready for integration into open-loop systems.

7–8 mm Tubing Compatibility

The upward-facing nozzle has a 7 mm minimum outer diameter and accepts tubing with a 7–8 mm inner diameter. Nozzle length is 15 mm, giving enough room for secure clamp or compression fittings. Builders must verify their loop uses matching tubing; larger or smaller hose sizes will not seal correctly on this block.

Compact-Footprint Loop Builders

This block suits enthusiasts assembling space-constrained loops where a 40 x 80 mm footprint fits but larger cold plates will not. It is not intended for builders who need multiple inlet or outlet ports, integrated temperature sensors or a mounting kit bundled in the box. Buyers requiring a ready-to-mount CPU kit with brackets and backplate should look at a different product.
