Ok, so the other day I got a brand new Asus 680 DirectCUII card and a shiny new EK 680 DC2 waterblock to go with it.So I installed it yesterday, everything went perfectly, and I was up and running in no time.Left the PC on over night, and then morning, upon inspecting the back of my PC I notice the water has suddenly gone a harrowing copper/orange colour, as if something has spontaneously corroded! My PC has been totally clean for months on end, water is a pure mix of de-ionsied and anti-freeze. So it had to be the new EK waterblock.Sure enough I take off the silver 'bling' plate and immediately see the following...So yeah, I think those pictures pretty much speak for themselves. The last two however, are after I cleaned up the stupidly 'why-the-fuck-EKbling plate'. You can see the 1-2mm holes of devouration peppering the inlet/outlet first contact points opposite thewaterblock.I dunno if this is a bad block that slipped past QC, or if that reaction is coming from my copper CPU block and/or copper radiator. Both of which were totally clean and corrosion free after all this. All the damage seems to be blatantly highly concentrated precisely at the first contact point between the Nickel waterblock base and Aluminium bling plate.I can't be bothered to write any more having spen the last 7 hours cleaning all this shit out of my whole PC. Did my Laing DDC plexi pump top right in.Well I would send it back but I wanna use my PC now dammit, so being the pragmatist I simply cut an appropriately shaped piece of overhead projector film and put it between the bling plate and where it would contact the water. Problem solved. Well, we'll see tomorrow morning I guess...
