Seems to work well for them. I dunno. They use the same fluid in all the different series. Can't be all wrong. I'd throw a Killcoil in their for good measure myself.
You do know that the reason why Corsair uses a Propylene Glycol based solution is because their radiators is made of Aluminium? so is Antec"s h2O series.. They have 2 OEMs that I know of that makes their radiators, one is CoolIT, and the other is Asetek. They are just made to specification and branded Corsair and Antec.
OP: Silver Coil and Distilled in the way to go, once you have the science down packed, then you can fiddle with dyes if you like.. I suggest just using colored tubings, silver coil and distilled..
If you still really want to use dyes, I have used Mayhems and they are very good, they don't even stain my tubings (tested with Primochill Pro LRT and Tygon 3603)..
