Good start...
Are you going to measure the coolant temp? How? Are you going to use straight water, or add something to it?
Remember to report the room temperature and humidity, for each testing session.
What rad did you have in mind? What fan(s)?
How are you going to handle the different barb sizes?
Since you made the PM public, I guess I'll finish it here, if that's OK (I assume yes).
1) AGREED. You're all set there.
2) measure the coolant temp.
3) As for the different OC results with same temps, I think that it may come from an irregular contact with the CPU core, where the block contacts the hottest area of the core better than where the diode is. I'd guess that the L1 ram is a great heat source. There's no fix for it, and I don't believe that there's any kind of testing that will help any, unless you start with some kind of theory, or idea why the result would be different. I'd suggest lapping the core, and either lapping the block, or at least checking it for flatness. You'd need a micrometer that's mounted on a table.
4) I'd measure the baseplate thickness, and post results for each pump. The big pump may not be necessary, but if you want to put in the time, then by all means do: it might turn out to be very interesting.
5) I agree. I think that the AS3 rumors are unfounded. I'm not so sure about the settling in period, but in any case yeah, BillA can set you up. Just please, describe how you are going to apply the AS3 (i.e. razor blade scrape after the application) in the highest level of detail as is possible. I can't stress this enough, because whenever someone has bad temps, and half the noobs out there do, it's because they didn't apply this paste right. It also happens to be the single most performance restrictor that there can be, throwing off temps by 5 deg C, very, very easily. Clean using what the AS website recommends, maybe even drop them an e-mail to double check. Another note, once it is applied, it is always there, no matter what you use to clean it, so it's a one time shot kind of thing, for the most part. If someone sent you a block on which they applied some cheap stuff, then you should ask them to either send you a new one, or advise them that it's going to be lapped again.
