Coolant XSPC EC6, liquid PC cooling coolant, red, 1 L

XSPC EC6 Coolant is a ready-to-use red liquid cooling agent formulated for desktop PC liquid-cooling systems and custom water-cooling loops. Supplied in a 1 L container, this coolant acts as the heat transfer medium between radiators, water blocks and pumps. The formula is based on refined vegetable extracts and includes non-toxic corrosion inhibitors and dyes, delivering compatibility with metals commonly used in PC cooling and tested suitability for acetal and acrylic plastics.

Advantages

XSPC EC6 offers high thermal conductivity combined with low electrical conductivity, helping efficient heat transfer while reducing risk from accidental leaks. Its non-toxic corrosion inhibitors provide protection for copper, brass, steel, nickel and aluminium, and the dye produces an intense red appearance for visual loop monitoring. The product is supplied ready to use, eliminating the need for dilution or additional mixing.

Suitable for

• Filling or topping up custom desktop water-cooling loops
• Routine coolant replacement in PC liquid-cooling systems
• Cooling single or multi-GPU and CPU custom loop configurations
• Systems using metal radiators, water blocks and pumps compatible with common metals and tested plastics

Key specifications

• Volume: 1 litre ready-to-use coolant
• Colour: red dye
• Base: refined vegetable extract blend
• Corrosion protection: inhibitors effective for copper, brass, steel, nickel and aluminium
• Electrical conductivity: low (formulated to minimise conductivity)
• Compatibility tests: tested with acetal and acrylic plastics
• Application: intended for closed-loop PC liquid-cooling systems

How to use

Before filling, ensure the cooling loop is clean and free of residue from previous coolants or biocides. Shake the bottle gently if required, open the container and pour the coolant into the reservoir or fill point following your system manufacturer’s guidance. Fill slowly to avoid air locks and run the pump at low speed to circulate the fluid while topping up until the loop is fully primed and all air bubbles are removed. After initial fill, check for leaks and monitor fluid level; top up as needed during the first hours of operation.

Recommendations

Use XSPC EC6 as supplied — do not dilute with water or other fluids. When mixing metals in a loop, ensure materials are compatible and follow manufacturer guidance for dissimilar metal protection. Perform routine maintenance by inspecting the coolant colour and clarity periodically and replace the fluid according to system usage or if contamination, cloudiness or biological growth is observed.
