Check this out!!
I have the solution and I will give you all the resutls in my upcoming article.
I used the four holes in the socket A mobo to use 1in square tubing to mount my waterblock on. I then used a 118 W pelt with a copper cold plate. This yielded me about the same as yoiu but a bit better. I am actually below ambient with a modded voltage mobo running 26C under load at 2.1 vcore (Its a KT7 RAID)
I used my regular power supply to power the 118W and then hooked up an old AT PSU to power a inline peltier which cools the water. The thing to pay attention to is that you dont want a really powerful pump. you want to keep the water in so it will cool as it passes through the waterblock with the pelt on it. I superglued a few of them on there, but ended up ruining too many waterblocks doing that, so I have a simple attachment mechanism which clamps the pelt on the waterblock. this stabilizes my temperatures, which really helps keep it under control under a load.
you can check out my little chapters of socket A watercooling at
http://www.athlonoc.com which will soon have another segment when I take this 600@1134 Duron out and put in a 750 blue core T-bird that has already hit 1200 with air alone.
BTW The 1000 I had at 1345 was crushed during preliminary tests of my waterblock attachment mechanism, RIP 1ghz core.
GOTTA LEARN SOMEHOW!!
I have a couple 24v 10A lambda PSU's for my .8 24v 172W drift pelt that i'll be putting on soon!! YEEHAW!!
