Wow! Very creative! I didn't see but what idle/load temps are you getting and how much does weather affect your temps? ex.) a warm day vs a cool day and also what about rain?)
Thanks for looking!
I haven't had much time for testing... but my initial CPU core 1 temps are 30C idle and about 43C loaded (stock clocks). I have went up to 3.55GHz and the idle temp went up to 40C and loaded it stayed around 55C.
The temps have been staying very stable and the outside ambient and rain have not affected temps. I suspect them to come down slightly just from the dirt settling around the copper tubing and creating better heat transfer (air is a poor conductor of heat).
I have a few days off this week and I plan on running prime95 for a while to see how much heat the loop can dissipate...
Also, I bought too small of a pump. It is only pumping around 70GPH.... My cpu temps should be about 5C lower but I have limited flow... I may be ordering a higher flow pump this week.
