We have been anticipating to see the unnamed passive CPU cooler from Noctua launched and on cabinets throughout Q1 this yr. This expectation was firmed up by a report in December confirming that these weighty finned and warmth pipe threaded constructions have been about to enter mass-production.
Those of you impatiently listening to followers whirring, whereas Noctua seemingly bides its time in releasing its fanless marvel, should not have for much longer to attend. In reply to a Fanless Tech Tweet, Noctua has stated that its unnamed passive CPU cooler goes to reach “very soon”. Thankfully the generally accepted interpretation of ‘very quickly’ is far narrower than of quickly.
To recap on the specs we all know, this fanless CPU cooler is touted as being good for CPUs as much as 120W, or 180W with quiet case followers current. It has an uneven design to assist with PCIe clearance and RAM stick clearance. Expect this product to price US$100 or extra.
Below is the Q&A bit on the subject of Noctua’s passive CPU cooler:
[RelaxedTech]: “Why would someone buy a fanless CPU cooler when they can run the NH-D15 with very low RPM speeds?”
[Jakob Dellinger]: “The key challenge is that for a passive cooler to be truly effective, design parameters such as fin pitch and fin thickness need to be quite different. You need a certain pitch to get low enough flow resistance for sufficient natural convection and a certain fin thickness in order to get the mass that is required for absorbing enough thermal energy. This means that different manufacturing machinery is required, e.g. much stronger stamping presses, etc. Getting this sorted in a reasonably cost-efficient way was quite a challenge. As for how big the market for this type of cooler is, we’ll actually have to wait and see. We found the technical possibility thrilling and hope that many customers will share this feeling. There’s a certain beauty and simplicity to going completely fanless rather than just running slow fans, there’s no real possible point of failure, less dust build-up, and of course, the bliss of complete silence.”
