XSPC Pure Coolant 1 L — blauwe UV-reactieve koelvloeistof voor pc-waterkoelingen

XSPC Pure Coolant 1 L is a pre-mixed blue UV-reactive cooling liquid formulated for custom PC water cooling loops. The non-conductive fluid is designed for continuous circulation through radiators, water blocks and reservoirs in desktop liquid-cooled systems. It supports thermal transfer, helps reduce the risk of corrosion in mixed-metal loops and provides a visible blue glow under UV lighting for system aesthetics.

Advantages

The coolant is ready to use without dilution and is compatible with most loop components made from copper, brass, nickel-plated parts, acrylic and PETG. Non-conductive properties reduce the immediate risk of electrical shorting in case of small leaks compared with conductive solutions. The UV-reactive dye produces a consistent blue fluorescence under UV/UV-A illumination to highlight flow and add visual effect while circulating.

Suitable for

• Custom PC water cooling loops with radiators, CPU/GPU water blocks and reservoirs
• Enthusiast builds that use UV or RGB lighting to enhance system appearance
• Maintenance or top-up of liquid cooling systems using similar coolant chemistry

Key specifications

• Volume: 1 litre ready-to-use coolant
• Color: blue, UV-reactive dye for visible fluorescence under UV light
• Electrical properties: non-conductive formulation
• Compatibility: suitable for metals and plastics commonly used in PC loops (copper, brass, nickel-plated surfaces, acrylic, PETG)
• Intended use: closed-loop liquid cooling circulation through radiators, water blocks and reservoirs

How to use

Flush the cooling loop with distilled water or a manufacturer-recommended cleaner before filling to remove residue from previous fluids. Fill the reservoir with XSPC Pure Coolant and run the pump at low speed to circulate fluid and purge air from the system; top up as needed until no air bubbles remain. Monitor for leaks during the initial run and verify material compatibility if your loop contains uncommon alloys or seals. Replace coolant periodically following routine maintenance intervals or if discoloration or particulate contamination becomes visible.

Recommendations

Do not mix with unknown additives or other manufacturer fluids unless compatibility is confirmed. Use distilled water for flushing and topping to avoid mineral deposits. Store the bottle tightly closed and out of direct sunlight; dispose of used coolant according to local regulations.
