Do you have an inline flowmeter as well to check if flow is being adjusted equally in all cases? How are you reading the CPU and water temps?
The flow meter thing annoys me. I *really* wanted to have one working for this review. I bought a couple, both restricted the flow so much that they would hardly even register movement. The initial plan to measure the blocks reaction to different flows didnt work, so I left the ball valve, and am going with full-flow and restrictive-flow. Just what flow/head rates we are dealing with here is beyond me. But the restricted flow measurements might be of some use, so I kept them.
I have a DMM which has a pretty accurate thermal probe, and I use my DigiDoc5 for the water temps, and they are pretty close. CPU temps are read from the Socket thermsistor of the KX7 which has been isolated with Neoprene and Silicone glue, and another digidoc probe. It's not perfect, but it shows enough small differences between the blocks to make a comparison. Yeah, I know all about the temperature compression and thermsistor innaccurasies, and Ive tried to keep those factors to a minimum.
