Corsair Hydro 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!

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.

Good quality like always

Key Features Pre-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. Pros Low Maintenance: Long lifespan (2-year warranty) and no mixing required 1. Performance: Effective heat transfer with minimal impact on flow rates 15. Cons Availability: 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.

Kept my computer cool and looks nice in blue

Had some overheating issues on my PC, and it turned out to be a whole load of fluid loss in the cooling system that had occured over time. I bought this as Corsair is a well known brand, and so far, its done the job. PC running quiet and cool, even when under some stress. Still have plenty left over as well after completely refilling my coolant system, so this will last me a long time in terms of being able to top up the system.

Perfect coolant for custom loops, amazing for temperatures

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

Good performance, colour is as advertized.

Bien reçu dans les temps, article correspondant à la description et parfaitement fonctionnel. Installé depuis 6 mois et impeccable.

Después de probar otros refrigerantes supuestamente de “baja conductividad eléctrica” que, con solo una gota, me causaron un corto y además generaron algas en poco tiempo, he vuelto al de siempre. Este de Corsair mantiene una excelente relación calidad-precio, es estable y fiable a largo plazo. Perfecto para quien busque un refrigerante duradero y sin sorpresas en su sistema de refrigeración líquida.

Liquide performant et facile à utiliser, idéal pour les systèmes Corsair Hydro X. Excellente protection et bonne longévité.

Très belle couleur de vert, légèrement transparent, du plus belle effet
