Thermaltake CL-W114-OS00TR-A C1000 Pure Clear Coolant

The Thermaltake C1000 Pure Clear Coolant (CL-W114-OS00TR-A) is a pre-mixed, 1000ml cooling solution engineered in Germany for custom PC water-cooling loops. Its formulation delivers four-way protection — anti-corrosive, anti-freezing, anti-rusting, and water scale prevention — helping to maintain both thermal performance and the longevity of your loop's internal components. Because it is pre-mixed, there is no need to measure concentrates or source distilled water separately; you simply flush your existing system with distilled water and pour the C1000 directly in.

One of this coolant's practical strengths is its broad metal compatibility. It safely contacts copper, brass, nickel, and aluminum, which means it can be used in mixed-metal loops without risking galvanic corrosion — a common concern with budget coolants. The fully transparent formula keeps your loop looking clean and works well in builds where you want the hardware to be the visual focus rather than a colored fluid. With a 3-year shelf life when unopened, it's also a convenient product to keep on hand for maintenance days.
