In a response to Fanlesstech over at Twitter, Noctua has confirmed its passive CPU cooler will be launching soon, most likely during Computex 2021 show.
Coming very soon! ;-)— Noctua (@Noctua_at) May 16, 2021
Unfortunately, there are still no details about the CPU cooler itself and all we have to go on is the prototype that Noctua showcased before. It is left to be seen if such a cooler will be able to cope with the latest CPUs from Intel and AMD, but in any case, we expect a high-end quality Noctua product.
Earlier rumors and the prototype pictured back at Computex 2019 show was a 1.5kg heavy unit capable of handling up to 120W.
Hopefully, we will hear more about it soon.
