I would pick the 3000 RPM ones and control them with a fan controller.
this way, whenever you want/need better cooling, just maxed them out (ie. benching)

That's always been the best way to do it, with high-speed 38mm-thick fans undervolted. The 3000RPM model doesn't get a good rep for its noises when undervolted, though (some people don't have that problem, but just saying).

What is a better choise for less noises when undervolted?

San Aces if you can find them cheap enough, or panaflos. Gentle Typhoons and S flexes are very good rad fans for the noise they make, gut out some cheapo 120mm fans for shrouds, using shrouds gives you a nice drop in temps for little money and drop in noise.

With a shroud how good would 120mm Scythe "Slip Stream" Case Fan (110.31 CFM, 37 dBA) be with fan control?

San Aces for 38mm-thick, and GentleTyphoons for 25mm-thick. Per Martin's tests, the GentleTyphoon has the best noise-to-performance ratio on a radiator, and San Aces (outside his review) have the best performance-to-voltage ratio. Choose the benefit that appeals to you more and you have your fans.

These are not good RAD or heatsink fans. Period. Because they can hardly breathe when any sort of restriction is put infront of them, for case fans they are fine however.

The San Ace H1011. That said, the 3000 doesnt make weird noises. ive has 5 for quite a while now, 1 even running in the dreaded horizontal position, which is supposed to "kill sleeve bearing fans in weeks to months"... so much for that, they all run brilliantly.

I remember suggestion him yate loons or panaflos for his rad

what the hell are you talking about. you cant suggest yates and panas in the same sentence... they're at the very ends of the spectrum in terms of quality. the panas being great, and the yates being cheap crap. the same goes for their pressures. yates have great value, but thats only because they're like 4 bucks each. aside from that, what does he need 64-84 CFM for? the 1000 RPM UK's will do fine. the Magicool isnt a horribly densely finned rad like the HW labs Gen Two series. (actaully, they'd do perfectly fine on those too.)

and you dont decide which fans you need based on the size of the rad alone. theres fin density, as mentioned, and the heatload is also important, as well as what delta T is deemed acceptable.
and since for "ultra quiet" loops, a delta well below 10C is fine, the OPs question is simple to answer, as i said, the UK1000's are great for the job. they offer decent static pressure so most of that 44 CFM actually gets trough the rad. a yate wouldnt even do half of its rated 47CFM trough a rad.

in short: 84 CFM is way overkill, only makes it noisier, yuo cant go by size alone, and dont ever mention a yate in the same sentence as a pana.

Way to go. +1 rep
