I disagree that a "vibrating membrane" qualifies as "solid state". It has moving parts.
If it's MEMS-based, then it's indeed not solid-state in the purest sense. However, what we really care about are things like durability, efficiency, size, weight, cost, and noise. So, I wouldn't get hung up on the solid-state thing. Plus, if you're starting with a mechanical solution, then you don't really need to replace it with a completely non-mechanical one. All it really needs to be is a better
mechanical solution, and that's enough.
For starters, the part where this thing's power consumption is 20% of its cooling capacity.
How much power do equivalent laptop fans use, at peak output?
- Comparing their mini vs. pro, the latter has twice the cooling capacity at less than 2x the power consumption, which shows it scales well. And the Pro actually consumes 16.6% of the power it dissipates, at 10.5 W of dissipation.
- If you look at the PDF link I posed above, you can see that their cooling solution scales somewhat linearly in power used vs. dissipated. Towards the low end, they claim it can dissipate 6.25 W while using only 0.5 W, which is a mere 8%.
Also, the "pro" branding is cliche and annoying.
I'll grant you that.
