Ok, so after my GTX260 died, I had to pull it out for RMA (I love EVGA ), so...down it all comes again..
Opening this piece, we have me lovely draining blob:
And in place:
Now, one thing to anyone new to watercooling, or just anyone designing a loop right now. Forget rad placement, forget pump placement, forget tubing conservation...the single most important thing in your loop is making a way for you to easily fill and drain it. With my first incarnation of this loop in this case I had filling down, but not draining. By this time tomorrow hopefully I'll finally have draining as well. ...it took me about 3 hours to drain a little over 2L from this loop...never again...
GPU is back in its stock cooler now, all screwed in and ready to go back to EVGA. All I need now is an antistatic bag big enough to cover it...
