First AirJet-equipped mini PC tested, Zotac's new ZBox has an incredibly thin chassis with N300 CPU

Zotac's ZBox PI430AJ mini PC is the first computer to use Frore System's fanless AirJet cooler, and as tested by HKEPC, it's not a gimmick. Two AirJet coolers were able to keep Intel's N300 CPU below 70 degrees Celsius under load, allowing for an incredibly thin mini PC with impressive performance.

AirJet is the only active cooling solution for PCs that doesn't use fans; even so-called liquid coolers still use fans. Instead of using fans to push and pull air, AirJet uses ultrasonic waves, which have a variety of benefits: lower power consumption, near-silent operation, and a much thinner and smaller size. AirJet coolers can also do double duty as both intake and exhaust vents, whereas a fan can only do intake or exhaust, not both.

Equipped with two of the smaller AirJet Mini models, which are rated to cool 5.25 watts of heat each, the ZBox PI430AJ is just 23.7mm thick, or 0.93 inches. The mini PC's processor is Intel's low-end N300 Atom CPU with a TDP of 7 watts, and after HKEPC put the ZBox through a half-hour-long stress test, the N300 only peaked at 67 C. That's all thanks to AirJet being so thin and being able to both intake and exhaust air.

For comparison, Beelink's Mini S12 Pro mini PC with the lower-power N100, which has a TDP of 6 watts, is 1.54 inches thick (66% thicker than the ZBox PI430AJ). Traditional fan-equipped coolers just can't match AirJet coolers in size, which is perhaps AirJet's biggest advantage.

Mini PCs aren't the only application that AirJet coolers would excel in. though. Mobile devices like laptops and tablets could possibly also ditch fans for AirJet and reap the benefits that Zotac's latest ZBox has. For higher-power chips, there's the AirJet Pro which can cool 10.5 watts of heat each. AirJet has even made it into datacenter storage, indicating that it's not just for low-power CPUs and could be used for a variety of components that produce heat.
