@Nik,

This is good news about your test station. I have been waiting for someone to test the MP-05 SP LE against these other blocks. I have an MP-05 and feel it is the finest of my blocks and have been very happy with its performance. I recently installed the FuZion and find it to be a very high quality block also and with less restriction it has a lot going for it. The MP-05 has a large surface area and performed as well as the FuZion on my current Presler p4d 945 @4.5Ghz.

I am looking forward to your results. And by the way, now ya got me thinking about a PA160 rad for a possible second loop for a NB and SB on either a P5W DH or an D945XBX2 since I have my DDC-2 replacement and might just try a little smaller tubing for them say 3/8"id.
