CorsairHydro X Series, XL5 Performance Coolant, 1 Litre (Vibrant Translucent Colour, Long-Life Composition, Enhanced Anti-Corrosion and Anti-Bacterial Inhibitors), Clear

Great coolant, used to replace the coolant in my old AIO, dropped temps by 7 degrees. Amazing stuff!

Perfect coolant for custom loops, amazing for temperatures

Key FeaturesPre-Mixed Formula: Ready-to-use with anti-corrosion and anti-bacterial additives for copper/brass/nickel components 112.Compatibility: Works with most coolants (e.g., Mayhems X1, EK Cryofuel) but not Alphacool Eiswasser or opaque fluids 13.Variants: Clear and translucent colors (e.g., blue) for aesthetic customization 12.ProsLow Maintenance: Long lifespan (2-year warranty) and no mixing required 1.Performance: Effective heat transfer with minimal impact on flow rates 15.ConsAvailability: XL5 is Europe-only; XL8 replaces it in other regions (do not mix them) 5.Price: Slightly costlier than some alternatives (e.g., €16.90/1L in Ireland) 12.Verdict: Ideal for Corsair-centric loops, but verify regional stock and avoid incompatible coolants.

Clear is the only way to go for hassle free maintenance. Coloured coolant may seem cool but is a nightmare to deal with. Unlike clear coolant you cannot see crud until it is too late, it stains your tubing, blocks and reservoir and almost impossible to clear if you change your mind. Last but not least. Clear coolant with basic LED lighting even in the most modest form allows you to achieve any colour you want at any time.

Very good product

Top quality

It's a conduit what is there to say

It looks great in clear tubes. It's a bit of a pain to dry if you spill some - you really need to wipe it, but otherwise it's good liquid
