Glacier EZ-Fit 450CPU Copper Block

The Phanteks Glacier EZ-Fit 450CPU is a copper CPU water block designed for custom liquid-cooling loops. It features an ultra-fine 0.15 mm fin array on a 3.7 mm thick copper base measuring 60.2 x 51 mm. Pre-installed 16 mm push-in fittings support both hard and soft tubing. Integrated Digital-RGB LED strips run at 5 V with a maximum draw of 0.3 A.

Compatibility and Use-Case Fit

This block suits builders assembling a custom loop on Intel LGA 1700 or AMD AM4 and AM5 platforms who want a tool-free fitting experience. The package includes an aluminium cover, mounting hardware, an Intel backplate and thermal compound. It is not suited for systems using sockets other than those listed, nor for loops requiring tubing sizes other than 16 mm OD hard tube or 16 mm OD / 10 mm ID soft tube.

Deciding Specification: 16 mm Integrated EZ-Fit

The defining feature is the pair of pre-installed nickel-plated brass fittings that accept 16 mm OD PETG, acrylic or PVC tubing directly. No separate fittings are needed, which reduces potential leak points and build time. If your loop uses a different outer diameter, this block cannot be connected without additional adapters.

Questions about this item

How does the 0.15 mm fin gap on the copper base affect real-world heat transfer?

The ultra-fine 0.15 mm fin array maximises surface area inside the block, allowing coolant to pull heat from the CPU efficiently without adding flow restriction.

What does the 5 V D-RGB header actually power on this block?

Two hard-board strips with five LEDs each draw up to 0.3 A and 1.5 W total, so a standard 5 V motherboard header can drive the full lighting effect.

Will the pre-installed 16 mm fittings accept both hard and soft tubing without extra parts?

Yes — the nickel-plated brass push-in fittings are built for 16 mm OD hard tube and, with the three included ABS inserts, 16 mm OD / 10 mm ID soft tube.
