P12s might be marginally better but I don't think it would be by much. The 38mm Scythes would probably yield slightly lower temperatures depending on your heat load, however that radiator does have the lowest fin density so slow speed fans work wonderfully with it as well.

The other 2 choices, Scythe S-FLEX series and Zalman ZM-F3 (probably would want to under-volt this though since it's rather noisy at 12V).

You'll do fine with either of those candidates, although if you're hyper-sensitive to noise, the P12's probably have the smoothest bearings, and the 1350rpm YL's will likely be the loudest.

The more different fans I try, the more I become convinced that fan rpm is more important than fan thickness when it comes to blowing through radiators. So by that measure, I'd expect the fans to all behave largely the same, although I'm not sure if the 1000rpm Ultra's would quite match the faster 25mm fans. My own personal favourites are the Scythe S-Flex for 25mm fans, and the Panaflo's for 38mm fans, but depending on your budget, I couldn't promise that you'd see enough difference to justify the money.

Try it with the YLs first, and if you find they aren't quiet enough for you, try something different. I've worked around Aircraft for over 25 years, so perhaps I'm not the best judge of what's "loud", but I'm quite happy with my YLs, and it's all I use.

Yeah they're good fans, but I wish I didn't buy the "F" ones, even though they do undervolt fine, still rather noisy to me at least. I run them around 1200RPM.

Yeah, I undervolt mine too. I find the D's don't undervolt very well, for whatever reason. A couple of my F's will consistantly go right down to about 450-500rpm, and pretty much all of them can run at 600rpm without any trouble. Whereas my D's all start coughing and false-starting at around 600rpm anyway. So as long as the controller will go low enough, might as well stick with the faster fans and keep my options open.

Bahhhh Noise this, sound that! Thats what a good set of Headphones is for.

Get a Delta / Panflo, and you'll never look back lol!!!!!

Actually, the Scythes are really nice, after selling my Aerocools to RS, I put my Scythe S's in the case, and have been rather happy with them so far.

Here is a low speed fan review on radiators.

My personal choice:
For 25mm fans Yate Loons.
For 38mm fans Panaflo's or Deltas.

Well I'm using the the one that's built into the Maximus Formula. I think I have it set at 80%, though I think my pump and other fans that came with my case are the noise culprits. However my PC isn't as loud as it used to be when I had my Antec 900 but I'd still rather a "silent" PC.
