I use my video card to leaktest; when the screen goes all crazy I know I've sprung a leak
Yes I had forgotten to list the original WW when I first posted but I'll definitely be reviewing it. I also PMed #rotor to see if he'd like me to review one of his blocks.
Did this DTek WW come straight from DTek as a review sample, or was it just purchased regularly by you without their knowledge it would be reviewed? I ask because I've heard that the bases of these are often the performance problem and that they need lapping. That doesn't seem to be the case with this block though the base looks fine.
