What I'm saying is that EVGA sold video cards with Innovatek blocks here before they developed their own "hydro copper" blocks. This was 8800 GTX/Ultra time, maybe even earlier (8800s were the first ones I noticed).
@Naekuh
Did you even bother to read my post?
If anyone wants proof that alu and copper mix fine with proper additives they just need to take a look at Aqua Computer's forum...
Again, I', not advocating the use of alu, I'm just saying that using alu and copper in one loop without getting corrosion is easily possible.
