At this year’s CES 2023, Frore Systems showcased their revolutionary PC cooling system that rethinks how to design a viable cooling system that is smaller, more effective, and silent. The company has created the AirJet, a solid-state chip that allows for active cooling and produces twice the cooling performance. It is highly compact, focusing on ultrathin notebooks and tablets, but it could cool larger systems in the future, allowing for more space in PC cases.
AirJet Mini & Pro from Silicon Valley startup Frore Systems will make you look at efficient cooling in a bold new way
Notebooks, phones, and tablets can get hot due to the workload. Manufacturers who design most of the popular 13-inch notebooks rely on passive cooling, which can reduce the processor power by up to seventy percent. This occurs when the processor heats to the heat limitations allowed (the thermal heat unit), which in turn will slow the processing down to let for passive cooling to take over, but in the process, you lose performance, and, as Frore Systems points out, “money.”
Frore Systems’ new AirJet active cooling device works uniquely differently from standard heatsinks. Imagine the same 13-inch ultrathin notebook with its relatively large heat sink to push air through a fan and out the bottom of the laptop. This can be a problem as if you are blocking those air slots, heat is trapped inside, and you lose the effectiveness of the device, causing “throttling” of the processor.
Frore System’s AirJet uses tiny vibrating membranes that create superfast pulsating jets, pushing the air out of the device forward instead of down. Using three airjet minis can be connected by a thermal copper strip that is connected to the processor and push the air out of the back of the 12-inch ultrathin laptop at 27 dB while doubling the processor power from 10W (since there is no proper way of cooling that thin of a notebook) to 20W of power. For larger systems, even more, processing power is saved, thanks to Frore Systems’ new AirJet cooling.
“As [the membranes] vibrate, they pull air in from the top — they create the suction force which automatically pulls the air from the top into the chip. And then the air is pushed down through, like a sieve at the bottom of the cavity. And it’s kind of like a showerhead, so the air comes through the top, and it’s pushed down through this sieve… And these [shower] jets are impinging on the copper heat spreader on the bottom. Heat transfer happens when these pulsating air jets hit the copper heat spreader. They extract heat from the copper heat spreader with very high efficiency, and then the air exits.”

The company, a Silicon Valley startup active for four years, is already working with Intel, Qualcomm, and GiS to incorporate the AirJet technology into the companies’ devices. However, the only information that we know at the time comes from Josh Newman, Intel Vice President and General Manager of Mobile Platforms, who is quoted that the new AirJet technology will be used with Intel Evo-based laptop designs in the future, and Madhavapeddy was unable to reveal any other future projects during his interview with PC World.
“A big advantage…is how your notebook operates when you place it on a pillow or a mattress. In a typical notebook, the inlet vents are at the bottom. You’ll see a lot of holes at the bottom of almost every notebook. And if you place it on a desk, that’s okay because they have little stacks to lift the notebook a little bit so that there’s a gap, and the air can go through the gap up through the vents at the bottom of the notebook into the fans. But when you place it on a pillow or mattress, those walls are all blocked, and the fans get choked. As a result, you don’t get the benefit of the fan.”
“We eliminate that problem because, in our case, you don’t need to have any vents at the bottom.”
