That's a damn good idea Blackeagle!, getting the jets alligned to the cups is a big part of it...

I think(from what I've read by Cathar) that impingment cooling is VERY localised, the area of metal around it that benifits is very small. So any 'large'(as if you could call them large!) areas of metal are just going to pass heat off conductivly, which will allow in a 'heat' build up, which results in a 'poorer' DT between CPU and block. Which leaves you with an average CPU temp. Basicly you want every square micron possible covered by the jet streams. 0.5 mm is what I'd aim for. Drilling that thin without the walls bowing is another matter!!, you may have to drill it in stages. I'd use a 2.5mm bit as well (sand down the tubes). As long as the area around the tubes (while in the cups) is not smaller than the tubes I/D~area it should'nt restrict it any...

Also if the jets are'nt centred it's going to magnify the problem...

Don't know if any is RIGHT but there's my thoughts!

...

How deep are the holes?, how thick (from drill~hole bottom) is the BP?. The BP wants to be under 1mm I expect. I'd like to try using 3mm thick copper for 2.5mm deep cups with the jets protruding just 0.5mm into them so the flow is'nt disturbed...

I think you'll need an X-Y table for the holes to get anywhere suitable for WW+ performance. They can be had for under £50 I think (for a half decent one) but I've never searched myself...

I would surely love some copper!. Was that from a scrappy?. Did they have any thinner stuff?. 3mm, 4mm, 5,, are all good sizes. Some 5mm stuff would be ideal but I'm not complaining

. the 10MM is ideal for GPU & NB blockage and I might be able to get some cut at an engeneering place, then again there's always the hacksaw

. I'm just chuffed you found some!, let the creativity flow!!

...

PS. From my small experience, working copper is a bitch. Getting drill placement without a 500watt bulb and a magnifying glass is a bitch too. You've done good for a first try (I had to gut my Rotor style block cause it was so fugged up

), I know the tendency to rush the first time!...
