Corsair Hydro X Series, XL5 Performance Coolant, 1 Litre (Vibrant Translucent Colour, Long-Life Composition, Advanced Anti-Corrosion and Anti-Bacterial Inhibitors), Red

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

Kept my computer cool and looks nice in blue

I really like the way the lighting in the pumps refracts through the clear coolant. The photo is just after filling so there is still bubbles in the liquid, even with the bubbles that iridescent type glow is really nice. I hadn’t sealed to move the pumps after taking the photo so had to drain, then refill, the system. During the refilling I had sealed of one of the fill ports properly. I got soaked in coolant. 2 days on, and 3 showers, later I can still smell, and feel, the coolant on me. Not an unpleasant smell; just a lingering smell.

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

Perfect coolant for custom loops, amazing for temperatures

Top quality

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
