Hello! I've had a watercooled PC for a number of years, but more recently it's been difficult to find EKWB Cryofluid Clear at reasonable prices. I'm thinking of switching to something like Mayhem's x1 coolant, or Alphacool's eiswater.
Any suggestions? Will it matter that some old fluid might still be trapped in a rad even after a flush? I'm hoping to not do a full teardown.
I'm thinking about going with this:
Uh... Why not water?
Generally, it's good to have biocides and corrosion inhibitors so the loop doesn't corrode or develop biofilms. I only need about a liter per year and would rather not have to keep separate bottles of biocide and inhibitor. And I'd need to find distilled water locally. For about $12, a premix is fine.
Battery water is quite readily available everywhere and it’s cheap.
