Miniature waterblock for GPU components

The Alphacool MCX One Nickel Edition 45 Degree is a compact liquid-cooling block built from copper with a chrome finish. It targets enthusiasts who want to cool graphics-card RAM or VRM areas directly within a custom loop. The 45-degree angled ports simplify routing in tight spaces around a GPU. It suits builders adding targeted cooling to an existing open-loop system.

Flexible mounting frees up loop layout

The block installs on RAM modules or VRM zones of a graphics card, letting you address hotspots that a full-cover block might miss. Its small footprint leaves room for other fittings and tubing runs inside the case. Because the component is reusable, it can move to a new graphics card when you upgrade, preserving the investment in your loop. Standard G1/4 threads connect to common soft or hard tubing.

Copper construction handles concentrated heat

The copper core transfers heat from high-density memory or power phases into the liquid stream efficiently. Nickel plating protects the surface from corrosion in mixed-metal loops. With no moving parts, the block adds zero acoustic noise to the system. Flow restriction stays low, so pump speed and overall loop pressure remain unchanged during normal operation.

Questions about this item

How does the 45-degree fitting angle affect loop layout in tight spaces?

The 45-degree orientation lets you route tubing around crowded VRM heatsinks or memory modules without sharp bends that restrict flow.

Does the nickel-plated copper block run hotter than bare copper under continuous load?

Nickel plating adds negligible thermal resistance; the copper core still transfers heat from VRMs or memory efficiently during all-day operation.

What fittings and tubing sizes are required to connect this block?

Standard G1/4 threaded ports accept any compatible compression or barb fittings matched to your chosen tubing inner and outer diameters.
