I wouldn't go with Koolance for anything; IMO their blocks don't perform well; and not to mention their RADs are aluminum, resulting in a mixed-metals loop.
are they alu? or plated? surely there not alu on the outside? they would be coated i would have thought. isn't that what zerex or what ever is for anyway?
According to Koolance their RADs are aluminum. Most RADs are also painted on the outside to achieve a gloss finish. Sure Zerex/Pentosin (or any engine coolant) will reduce the effects due to corrosion, but it's not a cure-all; not to mention, the purer the water, the more effectively it performs. Also, IMO their blocks are crap.
altough koolance blocks aren't the best it shouldn't matter as it's not like he's OCing the xbox 360 just Wcing it, the ultimate test is does it work? and it seems to, so stop drinking the hatorade. very nice work, but I'm not a fan of windows anymore but it is nice to show off that sort of workmanship
