hmmm, let me see... got 12x12mm area, maybe just a + or ||... or none at all... im afraid the height from the canal itself would affect the "jethole"...
it's a different situation on the first layout though... I wonder how the water will exit
what puzzles me is how many holes do I need (I assume a little bit larger than CPU core area should be occupied)
as seen from Volenti's work, he just worked out a couple of dimples
edit: just reviewed Volenti's block, I thought the hole was less than 1mm deep... argh! my eyes tricked me again!
btw, will be cooling 2 AXP 1700+ tbred Bs
