Water block Phanteks Glacier R220C

The Phanteks Glacier R220C is a transparent water block engineered for effective thermal management in custom liquid-cooled PCs. It measures 80 mm in width, 220 mm in depth and 34 mm in height, and is supplied as a single unit ready for integration into a cooling loop. The clear top exposes the coolant channel and mounting area, allowing visual verification of flow while contributing a minimal, modern look to the build.

Advantages

The water block combines a compact footprint with an extended contact area to improve heat transfer from the cooled component. Its transparent construction supports visual monitoring of coolant flow and adds a discreet aesthetic element without increasing system height significantly. The unit is designed to be compatible with standard fittings and mounting approaches used in custom loops, enabling straightforward installation and maintenance.

Suitable for (tasks / use cases)

• Custom PC liquid-cooling loops where a slim, transparent water block is required
• Systems requiring visible coolant flow for monitoring or presentation
• Compact or mid-tower builds with limited clearance but need for efficient heat dissipation

Key specifications

• Material: transparent acrylic top with metal cold plate
• Dimensions: 80 mm (W) × 220 mm (D) × 34 mm (H)
• Mounting: standard mounting pattern compatible with typical water-cooling hardware
• Cooling principle: direct liquid contact to cold plate for conductive and convective heat transfer
• Connections: standard G1/4 or comparable threaded ports for fittings (compatible with common fittings)

How to use

Install the water block into the loop following the case and motherboard manufacturer guidelines for component clearance. Ensure the cold plate aligns with the component surface and secure the block using the supplied screws or compatible fasteners. Connect inlet and outlet fittings with appropriate tubing, then perform a pressure and leak test before powering the system. Use compatible thermal interface material between the cold plate and the component to ensure optimal thermal conductivity.

Usage recommendations

Use corrosion-safe, manufacturer-recommended coolants and maintain routine loop checks to prevent deposits and ensure consistent flow. During installation, verify clearance in the chosen chassis and route tubing to avoid kinks or stress on fittings. Periodic flushing and coolant replacement prolongs performance and preserves the transparency of the top cover.
