Anyone here use any additives with the fluid you use in you IC? what results have you gained? I'm just curious if the Chill Charger from WBS is worth a damn or not. Personally i've ONLY used distilled water and its worked good, biut if I can get more of a gain, I WANT IT!I'm not interested in ice boxes or anything like that, i'm just interested in fluid in a standard system. What do you guys do? Thanks...
