How do you know with certainty the biocide used doesn't have some sort of chemical that causes the orings to shrink or harden?
How do you know the required coolant doesn't also have bearing lubricating qualities absent in water?
A corrosion blocker wasn't used, How do you know for sure there wasn't a flake of nickel that peeled and got caught in the bearing?
The first question is why Swiftech started putting tamper stickers on their 35x pumps. Too many users were RMA requesting pumps that were water damaged.
#2 who knows?
#3 A lot of automotve coolants do, why wouldn't there be some lubricating benefit. I don't think it matter much, but not using the required coolant opens up all sorts of uncertainty that could very much be due to the Users choice to NOT follow the coolant rule.
#4 another unknown because the required coolant wasn't used.
Bottom line, if you decide to run distilled water in most watercooling products as opposed to following the manufacturer require coolant rules, you have to take ownership in choosing that route.
I am a distilled user myself, but i accept responsibility if something happens.
Sorry to see this but as DIY watercoolers brewing our own coolant mixes we have to understand there is risk in what we do.
