hey guys, can anyone help me with the coolant mixture,I've read so much about it that i'm confused.On a low buget I was hoping for some home remedies.I know distilled water is involved but thats as far as I got .there are a couple of things I should mention. I have two alluminum waterblocks. The ZW-GS8800GTS on two asus 8800gts in sli and a swiftech copper block on the cpu,I've heard that it isn't recomended to mix metals in the same loop,but my buget didn't think so.Now i need a solution.just so you can get an idea its a EVGA 680i MB,two gigs OZC pc8500 1066MGz,intel quadcore Q6600 2.66 MGz,zalman xfinity 650watts powersupply,500gb western digital caviar green,and two asus 8800gts in sli.in a lian li pc-V1100plus.a 360 radiator mounted vertically at the back of the case.a swiftech pump and res.and home depot 's special black tubing.Thanks.
