Water block Phanteks EZ-Fit 450 Acrylic Copper POM Black Silver

The Phanteks EZ-Fit 450 Acrylic Copper POM Black Silver is a CPU water block designed for custom liquid-cooling loops. It combines an acrylic top, a full-copper base with fine micro fins, and a POM mounting structure. Two integrated 16 mm fittings are preinstalled to let you begin loop assembly immediately; the copper base uses micro fins down to 0.15 mm for increased heat transfer, while the metal mounting system with two springs ensures stable, balanced contact with the CPU.

Advantages

This CPU water block features a 100% copper base with a large surface area and 0.15 mm micro fins for improved thermal conductivity. Integrated 16 mm fittings eliminate the need for immediate additional adapters and speed up loop installation. The all-metal mounting system with dual springs provides consistent, even pressure on the CPU for reliable contact and stable cooling performance. The block's acrylic top and POM components offer a combination of visual clarity and durable mechanical properties.

Suitable for

• Custom PC liquid-cooling loops for desktop CPUs
• Enthusiast builds requiring a compact CPU block with high thermal transfer
• Systems where quick integration is needed thanks to preinstalled fittings

How to use

Install the water block onto a compatible CPU socket following your motherboard and case manufacturer's instructions. Connect tubing to the two integrated 16 mm fittings and secure with appropriate clamps or compression fittings. Check that the metal mounting system with springs is aligned and that the block sits flush on the CPU. Fill and bleed the loop according to standard liquid-cooling procedures, then verify there are no leaks before powering the system.

Recommendations

Use coolant and tubing compatible with copper components and regularly inspect all fittings and seals. Tighten mounting hardware evenly to maintain balanced spring pressure; avoid over-tightening. Follow standard leak-testing and maintenance intervals for custom loops.
