“Blowing hot air”: review of tiny Zotac mini PC that comes with innovative silent cooling chip finds out that it works pretty well — but heatsink and fan makers don’t need to worry just yet

The Zotac ZBox PI430AJ mini PC, fitted with the Frore Systems AirJet cooling system, didn’t exceed 70 degrees Celsius

Frore System’swidely anticipated fan-free alternative cooling method, which has found its way into the Zotac ZBox PI430AJ mini PC, performs as well as you’d hope according to a review of the device.

The two AirJet coolers keep the CPU fitted inside this tiny PC (a 12th-GenIntelN300 mobile processor) to below below 70 degrees Celsius when stress-tested, according toHKEPC.

Frore’s novel system has long been thought to feature in a handful of machines — includingother Zotac mini PCsincludingthis device in particular.

The use of this cooling system has allowed the manufacturer to compress the form factor, with the mini PC no larger than a deck of cards – with specific dimensions of 114.8 x 76 x 23.7mm. Its chassis is also made from aluminum, which allows for more heat loss through dissipation – to aid the Frore system that’s built into it.

This device also features a handful of useful ports including USB-C 3.2 Gen2, two USB-A 3.2 Gen2, a Micro SDCX card reader, a DisplayPort cable, HDMI 2.0, and Ethernet connectivity – alongside a 3.5mm headphone jack.

Unlike a conventional cooling fan, Frore’s technology – which is attached to an aluminum heat sink – relies on the high-frequency vibration of a film in the chip to promote airflow and the extraction of air. This vibrating film generates a strong enough force to suck in air and convert it into a jet-like discharge through the build-up of pressure.

When tested, the CPU didn’t exceed a temperature of 57 degrees Celsius with 99% load initially, according to the publication. This is because the AirJet system only intervenes with the internal temperature exceeds 60 degrees. Otherwise, at temperatures below this point, the system relies purely on passive heat dissipation.

When put under a 99% load for 30 minutes, the system reached a temperature of 67 degrees Celsius – which is still fairly low compared to other systems. However, we can’t be confident the technology will necessarily translate itself to more powerful systems until we see this embedded in thebest PCsand thebest workstations.

The Intel N300 CPU is relatively underpowered compared to thefastest CPUsout there, so it’ll likely take an awful lot more than just two AirJet units to keep those monstrous systems to comfortable temperatures consistently. There’s every chance heat sink and fans will be with us for a few more years yet before we can safely say their time is up.
