Just thought I would share the results of some of my weekend tinkerings. I reworked my plumbing a bit so that the radiator feeds directly into the waterbock now instead of first passing through the pump. I was also able two twist the bolts of the maze2 a couple of notches tighter and luckily without significant blood loss and/or any other kind of damage to myself or the block.
After doing the above, I got another 6 or 7 degree drop so that I am sitting at about 7 degrees C after 30 minutes. I think I still have some room for improvement, but I am somewhat more satisfied with the results thus far based upon the results of the little pelier calculation program I am using (writtem by Miles Asvachin from this forum). I don't know how complete my input parameters are, but according to it, the min temp I should be expecting should be around 6 degrees.
Anyway, I have not idea how some out there are consistently getting in the -10 degree range and beyond, but another reason I think my temps are OK is that I am still unsure how accurate my cpu temp reading is. I have been querying the forums at anandtech and amdmb concerning the thermistor configuration of the Dragon+ but have been unable to dig up any definite answers. Regardless, if I peek underneath the layers of my neoprene insulation I can see some definite frost on the corners of the cold plate.
Anyway, concerning overclocking my Athon 1.4 (1600+), I haven't done any extensive testing as far as stability and stuff goes. As yet I have not unlocked my Athlon XP though I have the silver laquer and everything to do it. However, I have been able to successfully boot into win2k at 10.5 X 150 = 1575 with default voltage and have been able to boot as high as 10.5 X 170 = 1785 at 1.85V however at that point I think I am beginning to push the limits of what my Crucial ddr memory can handle. Despite this, with the added voltage and speed, I only saw about a 3-4 degree rise in cpu temp which I think might be encouraging.
Also, one last note about PSUs. I really need to thank you guys again for the great info you've given me on this thread. I never really knew before what to look for in a power supply and I have been noticing for the first time what some of the PSUs I am using are actually capable of. For example, my two old 230W PSUs that I am using for the peltiers are both rated for 9 amps, however some of my bigger 300W and 400W PSUs used to actually power my systems are only rated for 6 and 8 amps respectively which I find strange, but good to know nonetheless. I don't know if there are actually AT PSUs rated for 13 amps, but I know what to watch for now and I'm sure I could at least find a couple of 10A ones like those used in the article.
