120mm Fan Shootout?

I've been interested in testing how different fans will actually affect performance on a high-end heatsink (I'll be using the Thermalright SI-128 SE since I already own it).

Currently, I own a Scythe S-Flex 1600RPM fan (well, three, but I'm not testing all three), a Noctua NF-P12 fan, and the stock fans that come with the Cooler Master RC690 case. Since I'm going to be replacing some stock fans in the RC690 anyway, as well as filling in any empty fan slots, I'm thinking about doing a fan shootout to see exactly how performance is affected by using different fans. Here's the contenders I've got thus far:

Scythe Ultra Kaze 2000RPM 120x38mm
Panaflo H1 120x38mm
Yate Loon D12SH-12
Scythe Slipstream 1900RPM
Silverstone FM121 (I considered the FM123, but I didn't hear too many good things about it)

I feel these and the fans I already have are a good representation of the high-performance fans on the market that many people are considering for their own rigs. I'm open to changes though (Scythe does feel a little overrepresented), maybe throwing in one of those SilenX fans that people keep raving about (either about how good they are, or how horrible), or possibly trying another Noctua model, or maybe giving Sharkoon or Nexus a go. I kind of want to see that Enermax Magentic-Barometric fan in action as well.

I'm not testing more than 5 fans however, that will max out my current case, and I don't really want to spend money on fans that are just going to be sitting around.

Anyway, I'm just wondering how interested the folks on this forum will be in this project of mine. I'll be doing it anyway just to satisfy my own curiosity, but if I generate enough interest on this forum (as well as a few others I frequent), I'll be willing to invest the extra time in a few pretty graphs and charts, as well as speculations on fan noise. Fan suggestions are currently open, I probably won't be starting this project up until April, so if you've got any fans you'd really like to see tested, let me know. I'm shooting for a fair balance of silence and performance though, so I'm not bumping up to the Panaflo U1 or Ultra Kaze 3000RPM, that's just overkill, and I think we can all agree that a 120x38mm fan going at that speed will leave the competition in the dust.

I do like those reviews, but they're a bit out of my league. I don't have any sound measuring equipment, nor a way to measure airflow. All this will be testing is how well these fans can push air through a high-end heatsink based on what temperatures they give me at idle and loud, and how loud they are to my own ears while they do it. I'll try to test them at different voltages to see how that affects performance using the Noctua UNLA and LNA adapters, but to save time, I'll most likely only do that if the fans are noisy.

Not really - I've seen that review before, and I know I couldn't begin to compare to it. However, what I'm doing here is more of a real-world performance test to see exactly how much better these fans do at cooling a processor. High CFM numbers are nice and all, but if it only translates to 1c under load, is it worth it anymore? That's my goal here.

Not in the slightest, I've read over both those reviews before (very interesting by the way), but I'm going for a more real-world style test here. I'm just going to see how much processor temperatures can benefit going from a crappy fan (stock Cooler Master) to a high-performance/low-noise fan, to a seriously high-performance fan. Those reviews only inspire me to try and be as objective and accurate as possible.
