Coolant XSPC EC6 — green PC liquid coolant for water-cooling systems

XSPC EC6 — green PC liquid coolant for water-cooling systems is a ready-to-use, coloured coolant formulated for custom desktop water-cooling loops. Based on refined vegetable extracts and engineered corrosion inhibitors, the fluid circulates through radiators, CPU/GPU blocks and tubing to transfer heat away from components while protecting metal and plastic parts. The green EC6 provides high thermal conductivity with low electrical conductivity, and its dye system is compatible with a wide range of loop materials. The EC6 Opaque variant contains a stable white colour base that resists separation and excludes zinc oxide and titanium dioxide to minimize pump wear and reduce the risk of clogging.

Advantages

The coolant combines eco-friendly base fluids with non-toxic corrosion inhibitors and dyes to provide metal protection for copper, brass, steel, nickel and aluminium, while being tested for compatibility with common acetal and acrylic plastics. Its formulation delivers improved heat transfer performance and low electrical conductivity for safer operation in the event of small leaks. The opaque formulation is stable over time and is designed to be pump-friendly and non-clogging by avoiding particulates such as zinc oxide or titanium dioxide.

Suitable for

• Custom PC water-cooling loops (CPU and GPU blocks, radiators, reservoirs)
• Routine coolant top-ups and full coolant changes
• Systems using mixed metals including copper, brass, steel and aluminium
• Loops containing acetal or acrylic hardline and soft tubing

Key specifications

• Formulation: ready-to-use liquid based on refined vegetable extracts
• Colour: green (opaque variant contains a stable white colour base)
• Compatibility: safe with copper, brass, steel, nickel and aluminium; tested on acetal and acrylic plastics
• Thermal properties: high thermal conductivity suitable for PC heat transfer
• Electrical conductivity: low to reduce risk in case of leaks
• Corrosion protection: contains non-toxic corrosion inhibitors
• Pump friendliness: opaque variant free from zinc oxide and titanium dioxide to reduce clogging

How to use

Drain the existing loop fluid according to your system’s maintenance procedure and flush the loop with distilled water until clear. Install or reattach all fittings, blocks and radiators and ensure all connections are secure. Pour XSPC EC6 green coolant into the reservoir slowly until the loop is filled, then run the pump (with the system powered appropriately per manufacturer guidelines) to circulate and purge air from the loop. Repeat filling and purging until no air pockets remain, then top up the reservoir to the recommended level. Inspect all fittings for leaks and allow the loop to run for a short burn-in period while monitoring temperatures and flow.

Recommendations

Use distilled water for initial flushing, avoid mixing EC6 with incompatible fluids or concentrated additives, and perform periodic inspection and replacement according to operating conditions. Store the coolant sealed in a cool, dark place and follow standard safety guidance: avoid ingestion, keep out of reach of children, and clean spills promptly. For optimal results, perform a full coolant change every 6–12 months or sooner if contamination, colour change or reduced flow is observed.
