Device uses movement of ions to generate airflow without any moving parts like in iPads and MacBook Air.
minus-squareryannathans@aussie.zonelinkfedilinkEnglisharrow-up2arrow-down10·6 hours agoYes but they generate more airflow than the fan alone can
minus-squaresplinter@lemm.eelinkfedilinkEnglisharrow-up14·4 hours agoThey do not. For a given power input they produce less airflow at lower velocity than a regular fan. They’re a complete scam.
minus-squarehOrni@lemmy.worldlinkfedilinkEnglisharrow-up21arrow-down1·edit-26 hours agoI recently watched some YouTube video that debunked that claim. They are basically pointless. Edit: https://www.youtube.com/watch?v=ySSo5PmZZJM It actually works better when You take the inner fan out of the casing. So they are actually a scam.

minus-squareEvil_Shrubbery@lemm.eelinkfedilinkEnglisharrow-up7·6 hours agoThey literally generate as much as that small fan in the case can generate. With the aerodynamics of the case it’s just a matter of converting higher pressure into lower pressure with higher (& a bit more laminated) airflow.
