Noctua is teaming up with Forced Physics DCT to explore whether the company’s JouleForce micro-channel array-based cooling can be adapted for desktop PCs and workstations. The long–term partnership will focus on developing a quieter way to use the tech, although Noctua said in its announcement that the partnership is not tied to any specific product or release date.

Claimed to be a new third path to cooling, JouleForce goes beyond traditional air and liquid cooling methods. While it is still based on air-cooling, its capabilities far exceed today’s modern CPU coolers, with the ability to cool over 2000W of thermal energy. The technology uses densely packed micro-channels designed to improve heat transfer. According to Forced Physics, its geometry prevents the boundary layer that normally forms along cooling surfaces, allowing heat to be extracted along the entire length of each channel. This essentially enables large amounts of heat to be removed using air alone, without requiring a liquid-cooling loop.

While that sounds impressive, bringing the technology to desktop PCs comes with a major challenge. The micro-channel arrays currently have a pressure drop that is “an order of magnitude and more” above the range of conventional PC fans. Thus, in its current state, JouleForce relies on industrial blowers, high-speed centrifugal fans, or even vacuum pumps to push air through the arrays.

Noctua’s expertise could prove useful as the company is known for developing some of the best performing PC fans. The partnership will investigate ways to reduce the pressure required by the micro-channel arrays or generate the necessary static pressure without making desktop systems excessively loud. “The pressure levels this technology requires in today’s implementations are currently supplied by equipment nobody would want on or under their desk, so this is a demanding, long-term engineering task – and one that we are eager to tackle,” said Roland Mossig, CEO at Noctua.

For now, Noctua and Forced Physics are still in the early research stage, with both companies planning to share updates as the project reaches significant milestones. If the two companies can crack the airflow and acoustic challenges, JouleForce could eventually make its way to desktop PCs. At the same time, Noctua would have a serious advantage in the market compared to other heatsink manufacturers.

A premium PC DIY fan brand has announced that one of its prized spinners is being used in a 4K camera. Noctua says that its NF-A4x10 5V PWM was used by the CAIM1 camera designers due to its quiet, compact nature and strong airflow and pressure performance. This camera runs two intensive processing tasks simultaneously within a compact shell, high-bitrate imaging and cryptography, hence the need for active cooling to prevent throttling.

The CAIM1 is something of a niche product. It has been designed to create photo and video captures that one can say with certainty haven’t been altered or generated using AI. Noctua says it is “cooling a camera built to prove reality.” CAIM1 is short for Counter Artificial Intelligence Machine 1.

From the brief description provided by the source, this anti-AI functionality seems to work by piping the imagery directly from the lens/sensor through an “onboard hardware attestation with edge cryptographic proof generation” process. This is stored on the camera’s “immutable, decentralized storage, enabling the origin of the media to be verified independently,” says the Austrian air-cooling specialist.

Of course Noctua’s involvement was beneficial to the camera makers for its high-quality precision fans. The CAIM1 generates heat through its high-bitrate 4K imaging activity, its cryptographic processing, all within the confines of a compact handling-friendly shell. Other key considerations of the designers were precise PWM fan control, and finding a fan with minimal noise (as the camera records audio) and minimal microvibrations.

Noctua says its NF-A4x10 5V, with its PWM’s SSO2 bearing system and smooth motor drive fitted the bill. This tiny fan was leveraged in a unified single-airstream cooling design with custom anti-vibration mounts, situated right behind the image sensor. This directs air across the sensor’s alloy heatsink backplate, and which gets exhausted though the camera chassis left side.

Our nozzle-headed readers will also be pondering over the Prusa branding on the camera body. The simple answer is that the CAIM1 is still at the prototyping stage and these models have been prepared using 3D printers and Prusament PETG Noctua Beige and Noctua Brown for the outer shell and fan mount. CAIM1 devices will be showcased at a handful of trade shows in Japan later this month. However, commercial batches are targeting Q1 2027 availability.
