Description

Same as a regular "blade-less fan", this aerospike fan uses the principle below to move air: blowing a thin high-velocity smooth airflow from a continuous slot across the surface of the tube or toroid.

The difference is that the aerospike can generate a narrow and high velocity stream of air, but the regular blade-less is focus on moving large volume of air. More info and original designs

The fan size is 5015, you can just buy one, no need to strip down from your machine..

The fantastic design makes me want to try it out immediately. May I ask if the screw specifications are M2 or M2.5? The length is approximately around 34mm. If M2 is used, there seems to be too much gap (0.25mm on one side), but if M2.5 is used, there won't be any gap, making it difficult to fasten the screw. Could you please help confirm? Thank you!

Hi thanks for your interest, I use M2 x 30mm screw.

I like the dual battery holder, may I ask the if the batteries are 18650? and the total voltage is 7.4? does that mean the fan won’t run at 24v full power? thank you in advance!
