I meant Corsair's Hydro X coolant.Cryofuel clear? Yes I used it in 3 builds (2 active). My disassembled build had no issues with any of the components.
That being said, the one time I ran straight distilled water with biocide, I had issues with tarnishing the nickel plating on an EK block. I've heard the nickel plating on EK products are not the best, nonetheless, I will personally stick to pre-mixed coolants.
