i felt it was an insult when he told me to do more research because i DID my research and found that more then a few WC fluids have EG in thier mixtures.
further more i wasnt asking wat was the best because like i said...my setup works just fine. it was more of wanting to see other peoples opinions of why they would use those expensive ass cooling fluids when distilled water and anti-freeze(certain brands that offer corrosion protection and lube) works just as fine.
and as far as biocide goes, ive been running my WC loop for quite a while now...at least 7 months and i dont notice any algae growth or slime anywhere in my system when i opened it up to put it in my new case last month.
finally...why not antifreeze?
-gives my loop a neon green color which i think is neat
-doesnt harm anything
-lubes the pump
-keeps corrosion from happening (i have brass fittings going into a copper/aluminum cpu block)
-gal of distilled water and gal of antifreeze for $5
-50% fan speed and i get 31C(house is 24C so its only 7c over ambient)
