How did it work for you?

pretty easy. No hitches.....

Good, hope it stays that way.

I did the impossible and solderd a copper fitting to my Al top forthe center inlet. Going to hook it up tomorrow right after I ship Fixittt the Z4. The Z4 is actually doing pretty good after I milled the channels out. Anyway I will have a pic of this disaster looking top tomorrow. This is just going to be for testing. If the block cools to my satidfaction I will make a manifold for the top somehow to route to the outlest into one. Not sure where to place the outlet though as there isn't much room with the center inlet.

Alright here is the nasty pic!!! Who said aluminum and copper can't be soldered together. Getting the air out now. Will fire it up shortly.

So far so good!!! 6C over water temp at 35C load. XP1600+@1524mhz 2.05Vcore 145FSB.

This could be the block I stick with. Easy/fast to mill. I just need to work on the duel outlets and some minor tweaks and it should be a good block. I got the one in copper started. Once I make some $'s I will pick up some better tooling to finish it. I am not sure if I should leave the top with 1 in and 2 out or if I should make a manifold for the top. I don't want to restrict flow any. I am happy with these results!!!

maybe you need to play with the little rectangles in the middle to get better temps, make the circle larger, or make an oval instead, there are heaps of mods you could do

I don't know how much better it can get no matter what I do. It is steady at 6C over water temp with the overclock. I plan on making larger center fins on the copper one I started. They will go about 1/4" up instead of the 1/8" they are now. Unfortunatly I cannot get any smaller bits than 1/8" that will work with my mill. I need a 3/8" shank endmill and 1/8" is a small as they make in that size of shank. I used to be able to use collets and go smaller but I messed up my mill when milling that copper one. The bit bound up and tightened the bit holder on super tight and I have no way of getting it off without damaging it. I already tried everything I could think of that would't hurt it anymore than I already have. Later in the year when work gets real good I may drop the $150-$200 to replace the screwed up part. But untill then it is 1/8" and bigger.

I think there is room for improvement though. I would like to get below 5C overclocked, but you can only get so cold no matter what the setup. If we could run the water through the CPU body itself we could drop it to near room temp, but that is not possible and never will be. As long as there is a gap between the block and the core and thermal compound is needed or CPU's start getting cooler we will not get much cooler than 5C below water temp I belive.

so the fins can't get much more complicated then....what about having an oval centre area, as large as the block size allows

Yeah I like the oval center idea, something i will have to work on. I want to try the copper one first to see if there will be a temp difference. That's going to be a while though. Out of cash and out of time.
