To operate a single CPU fan, use one or two small solar panels designed for small electronics. Silica material collects solar energy and converts it into direct current, or DC electricity. The voltage is sent through a series of output wires and can be connected directly to the CPU fan or to a toggle switch for added convenience.
Parts:
- Solar Panel - 6 Watt, 12 volt solar panel, Amazon or Ebay, $40
- Fan - 12 Volt, 0.25A CPU fan, $2-3
- Wires, from Walmart
