Mugen 2 Rev B costs around $40 while Silver Arrow/NH-D14 costs twice at around $80-85.
I expect the NH-D14 (and Silver Arrow) will lower the load temperature by around 5C for your i5 2500K. See pic below for the 2 coolers on an i7 870 (max TDP 95W same as your i5 2500K) at 4GHz for comparison. Sandy Bridge is relatively cooler than Lynnfield/Nehalem, so any top-of-the-line cooler will not be taken full advantage of (ie high bang-for-buck factor) unless you want to go near the extreme. But at that end of the curve, the law of diminishing return applies real quick.
Having said this, whether the money justifies this thermal delta, it has to be decided by you. If you are purely looking for thermal performance, using 2 fans to push-pull your Mugen 2 Rev B or using a single higher performance fan might also achieve very similar result, at the expense of the acoustic category.
My gut feeling is that if you are going after thermal, then it is not worth it as Mugen 2 is not that far behind.
However, if you are primarily chasing after acoustic and only secondarily thermal, perhaps it is worth it. Just a perhaps.Edited by windfire - 4/27/11 at 4:59am
