To recap on the specs we know, this fanless CPU cooler is touted as being good for CPUs up to 120W, or 180W with quiet case fans present. It has an asymmetric design to aid with PCIe clearance and ...

Noctua has previously claimed that this 3.3-pound (1.5-kilogram) cooler can cool a 120W CPU inside a closed chassis with no fans or a 180W CPU if the system has some degree of internal cooling.

But this occurred while the PC was running a CPU stress-test workload. Noctua previously planned on releasing the Passive CPU Cooler in Q1, but the company delayed the launch until Q2.

Noctua NH-P1 Passive CPU Cooler We have made very little secret of the fact that we here at eTeknix have been hugely anticipating this launch. In fact, with the only exception being when Noctua ...

The passive CPU cooler isn't built to handle a fully overclocked Ryzen 9 5900X or Core i9-11900K -- but if you want to run those chips and don't expect maximum boost clocks all day long, the ...

Noctua Passive CPU Cooler Known to have already been in-house tested with an Intel i9-9900K processor, this isn’t just a concept design for entry to mid-tier processors. It seems that Noctua has ...

It appears that Noctua's passive CPU cooler will be launching soon. In a response to Fanlesstech over at Twitter, Noctua has confirmed its passive CPU cooler will be launching soon, most likely ...

At most, Noctua's cooler is capable of running a CPU at just 120 watts inside an entire fanless case. If the desktop rig, however, has fans of its own, the threshold will then rise up to 180 watts.

In the end, I don't think I'll be doing a passive build with the NH-P1. I'm more interested in the Nofan CR-80EH Copper IcePipe 80W Fanless CPU Cooler ULTRA as a passive CPU cooler.
