The black tar stuff really baffled me, still haven't got to the bottom of it. Hence to say I've been a bit hesitant about filling the loop on my i7 build. I'm using the same pump, rad and the GFX2 had been thoroughly cleaned(thanks coka-cola, money's in the post)

I'm thinking about giving kill-coils a go, not even sure if that would prevent it.
Thanks Wez, you did get my PM! I agree it looks like it may be a Swiftech problem? Did you take any pictures?
