Palm-sized PC might contain the future of gadget cooling

I'm excited to see where this goes but needing two 1w Airjet Minis to cool one 7w CPU is a pretty terrible power ratio. I'm sure the 1.7 watt fan in my Win Max 2 is much louder, but it can cool a 35W APU.

As always with these things, it is important to keep in mind that there as some underlying physical restrictions.

The static pressure (1750 Pa) doesn't tell you much, if that happens to drop to near zero as soon as any measurable flow starts. With a power of 1W, the theoretical maximum flow at that pressure is 1.21 CFM, but it is probably much lower in practice. In any case, it is meaningless to quote the pressure without the CFM.

I remember someone on HN hypothesizing that these will be used in Apple's upcoming VR headset. (Can't find that comment, sorry )
