Sure, humans may disagree that 67C (153F) is cool, but it is for a semiconductor. More impressive, it was the temperature recorded on a CPU with a 150W TDP attached to a fanless Noctua NH-D15. Does that mean it was noiseless? Nope. The test kept each of the case fans maxed out at 12V input DC (100%).
This, without the fans.
Hardwareluxx does not specify how much air gets blown across the passive cooler. Their claim is that the case fans just ensure that the ambient temperature is as low as possible. That seems fair, but I could also, for instance, blow cool air through a 3-inch drier hose attached to a bathroom suction fan stuck out the window. That would certainly keep passive coolers chilled while only being technically fanless.
Theoretically, of course. I'm not saying it's something I did in high school or anything...
Depending on how long of a hose is used, it could even be noise in a different location (rather than case fans in the same PC). Still, cooling 150W is a feat in itself. Then again, with over two pounds of heat fins, it makes sense.

Known primarily for large and quiet CPU coolers, Noctua is not shy to attach a pair of 140mm fans to a chunk of metal. The NH-D15, announced today, can cool just about any current, mainstream or enthusiast CPU from AMD or Intel. It attaches to the CPU with a copper plate, which is connected to several copper heatpipes, which leads into two towers of aluminum fins. It is plated with nickel to prevent corrosion (I am not sure about the bottom).
As is common for these types of heat sinks, they are daunting to look at. Of course, that is not a bad thing, unless you have a very small case, but it might make you look at your stock fan differently. Noctua is claiming that their two fans spin at a maximum of 1500 RPM and a minimum of 300 RPM. This leads to a listed maximum noise value of 24.6 dBA, around the background noise of a quiet rural area at night.
The NH-D15 will be available mid-April for just shy of $100 USD.
