Product information

Description

THERMALTAKE CL-W246-OS00GR-A is a ready-to-use green antifreeze/coolant supplied in a 1 L bottle and formulated for closed-loop PC liquid cooling systems. Intended for CPU and GPU water blocks, radiators and tubing, this premixed coolant offers corrosion protection and temperature stability without the need for on-site dilution. The green color provides visual identification in multi-component loops and assists with leak and flow inspection during maintenance and refilling.

Advantages

This ready-to-use coolant eliminates mixing errors and speeds up system fill or top-up operations. It is formulated to provide corrosion inhibition for metals commonly used in PC cooling loops and to help maintain stable freeze and boil points appropriate for indoor system operation. The colored fluid improves visual monitoring of flow, level and potential contamination, while the 1 L volume suits routine maintenance or partial system refills.

Suitable for

  • Closed-loop PC liquid cooling systems for desktops
  • CPU and GPU water block fills and top-ups
  • Radiator and tubing maintenance and coolant replacement

Key specifications

  • Form: ready-to-use premixed liquid
  • Colour: green for visual identification
  • Volume: 1 litre per bottle
  • Intended application: closed-loop computer liquid cooling
  • Function: corrosion protection and thermal stability for loop fluids

How to use

Before use, ensure the system is powered off and unplugged. Drain existing coolant according to your cooling system manufacturer's instructions, then flush the loop if required to remove residues. Open the coolant bottle and pour the premixed fluid into the reservoir or fill port slowly until the recommended level is reached, avoiding air entrapment. After filling, run the pump briefly with the system off (if manufacturer recommends) and check for leaks. Recheck fluid level after a short run-in period and top up if necessary.

Usage recommendations

Use with compatible materials commonly found in PC loops (copper, brass, nickel-plated components, aluminium where specified) and avoid mixing with other coolants unless explicitly supported. Perform periodic visual inspections and scheduled coolant replacement based on system load and manufacturer's guidance. Store the bottle upright in a cool, dry place away from direct sunlight and out of reach of children.

Reasons to buy

Flow Like Pure Water

Engineered with a special formulation, P1000 Pastel Coolant delivers water-like flow for fast, consistent circulation in PC liquid cooling loops. Its low viscosity reduces resistance through tubes and blocks, improving coolant movement and heat transfer—measured to be about 26.4% lower than comparable coolants at 20°C and 25.8% lower at 40°C.

Reliable Anti-Corrosion Protection

Ready-to-use and non-flammable, this green THERMALTAKE coolant protects metals commonly found in cooling systems—copper, brass, nickel and aluminum—against corrosion. It provides long shelf life when stored airtight (minimum 3 years) and supports stable operation with a boiling point of 165°C (329°F) and a freezing point of -20°C (-4°F). Composition: less than 6% propylene glycol, water greater than 94%.

Environmentally Considered Formula

P1000 Pastel Coolant Series is formulated with biodegradable materials to minimize environmental impact and avoid bioaccumulation. Thermaltake designed this ready-to-use, color-coded coolant for easy maintenance, refills and top-ups in closed-loop CPU/GPU cooling systems without compromising eco-responsibility.
