I have to agree with maxim, the outer holes won't do any good imo. They will just restrict the waterflow that is coming out of the center jets. I suggest you make some plugs to plug some holes, that way you can test how many holes is the most efficient design. I think you will only need the most central jets since the core is not that big and you will only loose that valuable pressure if you use more jets (no matter the flow rate of your pump).

Well that is at least what i think, i may be completely wrong, i am just one of those 'lurkers'.

Yeah my thinking is that the water would invaribly go through the centre and this is where the main source of heat, but it the water will STILL run to the ends and down the outside "jets" even if the flow there were reduced compared to the centre and you'll be able to coll the "outer HS" much better than the cascade for example.

I think the desgn will work very well for pentium systems but like you said the outer jets coul become reduntact but only on systems that do no have a HS such as an Althon XP
