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.
