Yeah, I have my radiator on an open window sill. I should add that my temps were running genome@home, not prime95. My delta with prime95 is about 10.5C. I'm running 4-way interleave, CAS2, 2T-6T-2T, 4-level queue depth, Fast cmd decode...uhh, I prolly forgot some
Thanks for the advice on the helix. I'll use your suggestions and report the results.
It's odd with the Innovatek. Even though I'm getting lower temp readings, my computer is not completely stable. Sometimes prime95 fails, or I get a floating point exception. Also, my water temp reading were too high. With a better water thermometer, my water temps are about 1C lower than my CompuNurse readings. I've re-installed my hose barbs on the IT block so that they extend about as far down as the original fittings, so I should test it again. I'm tightening the IT block until it's impossible to turn the knob further, and the imprint from the core is perfect when I remove it.
Jim, I think the 8/32 is 1/4". I guess the diameter are always reported in 32ndth of an inch. I really recommend the nylon spacers. They help a lot.
