Product information

Description

Thermaltake CL-W246-OS00WT-A is a ready-to-use antifreeze and coolant supplied in a 1 L bottle for PC liquid cooling systems. Formulated for closed-loop and custom water-cooling loops, the white coolant requires no dilution and is intended for filling or topping up CPU and system cooling circuits. The single-unit bottle provides a prepared solution that is compatible with typical materials used in PC cooling assemblies.

Advantages

The coolant comes pre-mixed and ready to use, eliminating the need for measuring or mixing concentrates. Its white colour allows users to maintain a consistent aesthetic for visible tubing and reservoirs. Packaged as a 1 L bottle, it offers a practical quantity for refilling or performing maintenance on single systems. The product is presented as a single unit for straightforward purchase and use.

Suitable for

  • Filling closed-loop (AIO) liquid CPU coolers
  • Top-up and maintenance of custom water-cooling loops
  • Systems where a white coolant appearance is preferred

Key specifications

  • Volume: 1 L
  • Formulation: ready to use (pre-mixed)
  • Colour: white
  • Intended use: antifreeze/coolant for PC liquid cooling systems
  • Quantity: single bottle

How to use

Before use, verify compatibility with your cooling loop materials and consult the cooling system manufacturer’s instructions. For filling a closed-loop AIO unit, follow the manufacturer’s service procedures or authorized guidance to access the fill port if applicable. For custom loops, drain the existing coolant if required, flush the loop according to recommended maintenance steps, then pour the coolant into the reservoir or fill port until the loop is adequately filled and free of air pockets. Ensure the system is leak-tested and operates at recommended temperatures after filling.

Usage recommendations

Use gloves and eye protection when handling coolant. Store the bottle in a cool, dry place away from direct sunlight. If mixing or matching coolants from different manufacturers, proceed with caution and consult compatibility guidance to avoid possible reactions; when in doubt, perform a complete flush before introducing a new coolant.

Reasons to buy

Flow Like Pure Water

Thermaltake P1000 Pastel Coolant is formulated for exceptionally low viscosity, so it flows smoothly through custom and closed-loop PC cooling systems. Lower viscosity reduces resistance inside blocks and radiators, improving circulation and maintaining consistent heat transfer—at 20°C it delivers about 26.4% lower viscosity than typical coolants and remains significantly more fluid at 40°C.

Reliable Anti-Corrosive Protection

This ready-to-use coolant protects metals commonly found in PC loops—copper, brass, nickel and aluminum—against corrosion while offering long-term stability. It’s non-flammable, has a long shelf life of at least 3 years in airtight containers, and is supplied pre-mixed for immediate use. Key properties include a boiling point of 165°C (329°F) and a freezing point of -20°C (-4°F); formulation contains under 6% propylene glycol and over 94% water.

Environmentally Friendly Formula

P1000 Pastel Coolant is manufactured with biodegradable materials and designed to minimize environmental impact. The eco-conscious formulation avoids bioaccumulation and reflects Thermaltake’s commitment to producing greener cooling products.
