Product information

Description

THERMALTAKE CL-W246-OS00RE-A ready-to-use coolant, 1 L, red is a pre-mixed liquid formulated for PC liquid cooling loops. Supplied in a single 1-litre container, this ready-to-use coolant is intended for direct filling, topping up or replacing fluid in custom and all-in-one (AIO) liquid cooling systems. The red colour provides visible flow indication inside transparent tubing and reservoirs while the premixed composition eliminates the need for on-site dilution.

Advantages

This coolant is supplied ready to use, simplifying maintenance by removing the need to mix concentrates or measure additives. The product is compatible with common radiator, pump and water block materials used in PC cooling loops and is presented in a practical 1 L volume suitable for system refills or partial replacements. Its red tint improves visibility of flow and levels without introducing particulate additives.

Suitable for

  • Refilling or topping up custom liquid cooling loops in desktop PCs
  • Refilling AIO (all-in-one) liquid cooling systems where manufacturer guidance allows user top-up
  • Maintenance of radiator, pump and water block circuits in gaming and workstation rigs

Key specifications

  • Volume: 1 litre
  • Formulation: ready-to-use pre-mixed coolant
  • Colour: red
  • Intended use: PC liquid cooling loops (radiators, pumps, water blocks)
  • Packaging quantity: single 1 L container

How to use

Before use, power off and unplug the PC and follow manufacturer instructions for your cooling components. For refilling or topping up, open the reservoir fill port or follow the AIO manufacturer’s recommended access point and pour the coolant slowly to avoid air entrapment. After filling, run the pump at low speed to purge air from the loop, monitor for leaks and top up as necessary until the system runs without air pockets. Dispose of any residual fluid responsibly according to local waste regulations.

Usage recommendations

Use only with compatible materials and systems; avoid mixing with other coolant brands or concentrates unless explicitly stated compatible. Periodically inspect tubing, fittings and seals during and after fill to ensure leak-free operation, and follow system manufacturer guidance for maintenance intervals.

Reasons to buy

Exceptional Flow Like Pure Water

THERMALTAKE P1000 Pastel Coolant is engineered for outstanding fluidity—formulated to mimic the low viscosity of pure water so it moves through radiators, pumps and water blocks with minimal resistance. At 20°C the P1000 Pastel Coolant shows 26.4% lower viscosity than competing coolants and 25.8% lower viscosity at 40°C, ensuring smoother circulation and more efficient heat transfer in custom and AIO liquid-cooling loops.

Reliable Anti-Corrosion Protection

This ready-to-use THERMALTAKE coolant (CL-W246-OS00RE-A) delivers long-lasting corrosion protection for common cooling-loop metals including copper, brass, nickel and aluminum. Non-flammable and stable in storage (at least 3 years in airtight containers), the formula provides dependable protection while maintaining safe boiling and freezing characteristics: boiling point 329°F (165°C) and freezing point -4°F (-20°C). Composition: Propylene Glycol < 6%, Water < 94%.

Eco-Conscious and Biodegradable

P1000 Pastel Coolant Series is designed with the environment in mind. The biodegradable formula minimizes environmental impact and avoids bioaccumulation, offering a greener choice for maintaining or topping up your PC liquid cooling system in a vivid red color.
