Very powerful portable fan DIY ( Bitcoin ASIC 😂)

I made a very powerful pocket fan for my size (1.8" X 2.4" \ 4.5 X 6 cm) that will save you on hot days.
It is enough to take it out of your pocket, turn it on, and you will get a strong airflow that will cool you down.
To create it I used:
1. A server with a dual-rotor fan (for its operation, it is enough to combine the pros and cons of each fan) - alli.pub/6ew9wr
2. DC-DC converter - alli.pub/6ew9nt
3. Charging board with double protection function - alli.pub/6ew9sa
4. The battery is in my stock, you can also use any suitable size. (preferably high current battery)
