Wired's reviewer went into the demo expecting a dead mock-up behind glass and came out describing a machine that felt like a production unit, one he kept picking up off the table [17]. Lenovo's own words for the sample were "very mature and refined product in terms of sample stability" [13].
A fan moves a large volume of air at low pressure across a heatsink and shoves it out a grille. Frore's part takes the opposite trade: small volume, high pressure, aimed straight down at metal. Frore says each module makes ten times the back pressure of a regular laptop fan [8], which puts the fan it displaces somewhere near 200 Pascals [1]. The mechanism that pressure is meant to buy is the removal of the still-air boundary layer sitting on the copper, which Frore identifies as the thing that causes heat buildup and throttling [6].
Four modules sat along the top edge of the sample motherboard Lenovo had on the stand [7]. Divide the supported thermal ceiling across that count and you get five watts per module [3]. That is arithmetic rather than a spec sheet, but it is the arithmetic that tells you roughly how many modules a hotter part would want, and where a 10 mm lid would have to put them.
Lenovo's stated payoff for all this is thinner designs and quieter operation, plus reclaimed internal volume that can go to a bigger battery [3]. What Lenovo would not say is whether a shipping version keeps that class of chipset, or whether the module turns up in a variant of an existing laptop or mini PC line at all [15]. Wired's own caveat is the correct one: nobody knows how well this works until it is out of the demo room [16].
Whether any of this is yours comes down to two things: where your sustained workload sits relative to the ceiling this generation of the part supports, and whether your recurring thermal cost shows up as throttled clocks or as service visits. If the workload sits above that ceiling, the answer is to wait for a chassis engineered around the bigger version, not to read a concept built around the smaller one as a promise. Throttled clocks make this a performance question, and it can only be settled by a review unit held at load for half an hour, which a trade show floor is structurally incapable of producing [16]. Service visits make it a reliability question, and a reliability claim about a brand-new component is worth about one field season of returns data.
The question worth putting to Lenovo in the meantime is how much of the volume the vents used to occupy came back as battery [3]. That is the part of this a user notices at four in the afternoon.
