Coolant liquid XSPC Pure Coolant 1 L — pink UV-reactive cooling fluid for PC liquid cooling

XSPC Pure Coolant 1 L in pink is a ready-to-use coolant formulated for PC liquid cooling loops. Designed to circulate through radiators, water blocks and reservoirs, this UV-reactive cooling fluid provides visible fluorescence under UV/UV-A lighting while maintaining adequate flow and heat transfer in custom desktop liquid cooling systems. The product is intended for users who want a colored, UV-visible coolant without the need to mix concentrates or add dyes.

Advantages

The coolant comes pre-mixed for immediate use and reduces preparation time compared with concentrates or DIY blends. Its UV-reactive properties create consistent fluorescence under compatible lighting, improving visual monitoring of flow and circulation. The formulation is compatible with typical loop materials used in PC cooling — including copper, brass, aluminium radiators (with appropriate system maintenance), and common plastics in reservoirs and tubing — when used according to manufacturer guidance. Being a purpose-made coolant, it helps maintain stable flow characteristics and thermal transfer compared with plain water.

Suitable for

• Custom desktop liquid cooling loops for gaming and workstation PCs
• Aesthetic builds that use UV/UV-A lighting to highlight coolant color
• Systems with radiators, CPU/GPU water blocks and reservoirs requiring colored coolant
• Users seeking a pre-mixed solution without adding dyes or concentrates

Key specifications

• Volume: 1 litre ready-to-use coolant
• Color: pink, UV-reactive (fluoresces under UV/UV-A light)
• Compatibility: formulated for use in closed-loop PC liquid cooling systems with standard metals and plastics when maintained properly
• Application: circulates through radiators, water blocks and reservoirs

How to use

Drain and flush the existing loop according to the system manufacturer's instructions before introducing the new coolant. Fill the reservoir with the XSPC Pure Coolant until the loop is fully primed, then run the pump to circulate the fluid and remove air pockets. Monitor flow and check for leaks during the initial run-in period. Regularly inspect the loop and perform scheduled maintenance such as periodic draining and gentle flushing to preserve fluid clarity and system performance.

Usage recommendations

Use only in closed-loop PC liquid cooling systems. Avoid mixing with other coolants or additives unless explicitly stated as compatible by their manufacturers. Maintain routine loop maintenance, including periodic inspection for deposits, discoloration or biological growth, and replace the coolant if any contamination or degradation is observed. Keep out of reach of children and avoid contact with skin or eyes; in case of contact, rinse thoroughly with water. Dispose of used coolant in accordance with local regulations.
