Update (June 22-2013, 4:43pm EDT): I was contacted by Noctua about the TDP ratings… quoting from their email:
As for the question regarding the TDP rating of the original NH-D14, I'd like to stress that the cooler can *easily* handle any 130W CPU! Our D14 is renowned to be among the best performing heatsinks for overclocking on the market and and many users have pushed their CPUs well beyond 250W using this cooler.
Noctua apparently does not like including TDP values for their coolers because it varies heavily on the conditions (such as, of course, room and case temperature). It makes sense, of course, because then customers would go looking at reviews and see what overclocks were achieved with the system.
Yes, I know Computex is long over, but I missed something that I want to cover.
Noctua has been teasing active noise cancellation (ANC) for their CPU coolers for quite some time now; Tim published his brief thoughts, 13 months ago, on their press release leading up to Computex 2012. The prototype, this year, is a full unit rather than the fan from last year.
This design is a modified NH-D14 cooler with added technology from RotoSub AB to sample its own noise and destructively interfere. According to Noctua, this will be the first ANC cooling unit for a CPU. The plan, as their press release suggests, is to release a cooler with the model named "R-ANC" after its (R)otoSub (A)ctive (N)oise (C)ancellation (R-ANC) technology. To me, this seems like a confusing choice in name as it breaks away from their existing standard and limits choice in name for future models based on this technology. Personally, I would have preferred to see "NH-D14R" or "NH-D14ANC", but alas I am not a marketer.
Also, in the process of researching for this article, I have been unable to find a canonical TDP-rating for this device. I was not too surprised to have a difficult time finding it for this unreleased product, but TDP is even omitted from the established, albeit louder, default NH-D14. Some sources claim this cooler can support an Intel i7 Extreme processor, which typically requires a 130W thermal dissipation; other sources say you should be somewhat cautious with this cooler with CPUs >95W TDP; some even claim it is great for air-only overclocking. Rolling all of these sources together, assuming a kernel of truth in each, I would assume this cooler (and, by extension, its upcoming R-ANC variant) would be good for decent air-only overclocks until you reach the -E series.
But, grain of salt, have some.
No word of pricing, but Noctua believes they will have it available spring/summer of next year. For some reference, the default NH-D14 can be found for about $75-$100; expect the R-ANC to be slightly north of that.
