Thanks kibbler, back just started getting sore, and I kept ignoring it. Finally couldn't stand or walk. I crawled into the emergency room on my hands and knees two weeks ago, and they shot me full of demerol.
Anyway, I went watercooling because of noise too, so it's only going to be a matter of time before I'm back at it...and I'm not even using the 7K Delta this time.
No noise is good noise.
