Overview
Key Features
Better formula - by adding a liquid surface tension Optimizer, the P1000 Pastel Water Cooling Solution Series minimizes the risk of airlock.
Vivid colors - comes in five non-transparent colors; red, blue, white, Green and yellow. The latest TT formula ensures color saturation, stability and duration.
Flow like pure water - low viscosity enables its effective flow. At 20°C, P1000 Pastel water cooling solution has 26.4% lower viscosity than other coolant and 25.8% lower at 40°C.
Anti-corrosive solution - non-flammable and provides great protection for the entire cooling system from corrosion.
Eco-friendly - produced with the environment in mind, P1000 is made with biodegradable materials and does not pollute the environment or Bio accumulates.

Frequently Asked Questions
Is the P1000 compatible with copper, nickel, and brass fittings commonly used in custom loops?
Yes, the P1000's anti-corrosive formula is designed to protect mixed-metal loops including copper, nickel, and brass components. It will not degrade O-rings or acrylic reservoirs under normal operating conditions.
How does the viscosity of this coolant compare to distilled water, and does it affect pump performance?
Thermaltake claims 26.4% lower viscosity than competing pastel coolants at 20°C. In practice, this means your D5 or DDC pump will not need to work significantly harder than with distilled water, keeping flow rates and thermals close to clear-coolant baselines.
How often should the P1000 be replaced in a loop?
Thermaltake recommends replacing the coolant every 12 months. Over time, pastel pigments can settle or the anti-corrosive additives lose effectiveness, which may lead to buildup in blocks and radiators if left beyond the service interval.
Does the pastel pigment cause staining or clogging in microfin CPU and GPU blocks?
Pastel coolants carry suspended pigment particles that can deposit in fine-channel blocks over extended use. Flushing the loop during coolant changes and avoiding mixing with other brands minimizes this risk, but some residue over a 12-month cycle is expected.
What is the total volume, and is one bottle enough for a typical dual-radiator loop?
Each bottle contains 1000 ml. A standard dual-radiator loop with a 240mm and 360mm radiator typically requires 600–900 ml, so one bottle is usually sufficient with a small reserve for topping off.
