Alphacool Eisbaer 420 water suggestion


New member
Hi, I am planning to buy Alphacool Eisbaer 420 soon , and I would also like to buy extra coolant with it just in case when needed to be prefilled.
What coolant is inside Eisbaer 420 ?

I read in manual that there are two types that can be used, CKC or Eiswasser Crystal. I would like to use same as factory one, but I don't know what factory prefilled coolant is inside.
