TL;DR: Noctua and Forced Physics are researching whether JouleForce micro-channel air cooling can work in desktop PCs and workstations. The technology can dissipate substantial heat but currently requires pressure levels and equipment unsuitable for quiet desktop use; no desktop product or performance results have been announced.

Noctua is figuring out a different way to cool hot hardware without a liquid loop. On September 24, the company announced a research partnership with Forced Physics DCT to investigate whether its patented JouleForce micro-channel array technology can advance to desktop PCs and workstations. Noctua presents it as a long-term R&D effort rather than a specific product.

JouleForce forces air through arrays of tiny channels. According to the announcement, the geometry prevents the boundary layer that normally restricts air cooling from fully forming, so heat is pulled out along the entire length of each channel. This lets air alone move large amounts of heat without pumps, tubing, or liquid loops. Forced Physics says the tech can remove between 500W and more than 2,000W, depending on the design.

Noctua says the arrays create a pressure drop of at least an order of magnitude above the range standard axial PC fans are built for, so current setups depend on industrial blowers, high-speed centrifugal fans, or vacuum pumps. Increasing fan speed or utilizing multi-stage impellers could help achieve the goal.

Still, both ideas are rejected by desktop noise requirements, and sealing against air leaking around the array at these pressures is hard to square with the size and modularity of PC cases. CEO Roland Mossig said the pressure is currently supplied by equipment "nobody would want on or under their desk." Noctua's quiet, high-pressure airflow expertise is the reason for this partnership, intending to lower the required pressure or generate it within desktop limits.

Forced Physics pitches JouleForce as "liquid-class" air cooling for AI and data center chips, stating that conventional direct-to-chip air will not be able to keep up with the 1,000W to 2,000W range AI accelerators are transitioning to. The company also cites independent testing at Villanova University, saying Dr. Alfonso Ortega reproduced its thermal-resistance and pressure-drop results on an AMD EPYC SP5 setup within 3-5% and achieved 50% lower thermal resistance at one-third the airflow compared with a Dell reference heat sink. These figures come from server hardware and include no desktop performance or noise data.

Story Q&A

From TweakTown's coverage of this story.

What engineering hurdles must Noctua solve to make JouleForce quiet and compact enough for desktop PCs?

Noctua needs to overcome a pressure drop at least ten times higher than standard axial PC fans are designed to handle. Industrial blowers and other current ways of generating that pressure are too noisy or bulky for a desktop, while sealing the array against air leaks is difficult within the size and modularity of PC cases. The research aims to reduce the pressure JouleForce needs or generate it quietly within desktop limits.

How could JouleForce's high-pressure airflow and sealing needs affect compatibility with modular PC cases?

JouleForce needs pressure at least an order of magnitude beyond what standard PC fans are built to provide, and air must be sealed against leaking around its micro-channel arrays. That sealing is difficult to reconcile with the size and modularity of PC cases, so compatibility with desktop cases remains an unresolved part of Noctua's research.

How could Noctua's fan expertise help reduce JouleForce's pressure requirements within desktop noise limits?

Noctua is investigating whether its quiet, high-pressure airflow expertise can lower the pressure JouleForce needs or supply that pressure within desktop noise limits. Its micro-channel arrays currently need at least ten times the pressure standard PC fans are designed to provide, while faster fans or multi-stage impellers are considered too noisy. No specific solution has been announced.

What does Villanova University's AMD EPYC SP5 evaluation establish about JouleForce's performance at reduced airflow?

Villanova University's AMD EPYC SP5 evaluation found that JouleForce achieved 50% lower thermal resistance than a Dell reference heat sink while using one-third the airflow. Dr. Alfonso Ortega also reproduced its thermal-resistance and pressure-drop results within 3-5%. The test used server hardware and does not establish desktop cooling performance or noise levels.

Noctua, which has recently expanded beyond air coolers with its NL-LC1 AIO liquid coolers, says both companies will report on the collaboration as they reach important milestones. For now, JouleForce on a desktop remains a prominent theory, not a product.
