I used a calculator (found here) and input 12v to 7v, 0.16a (my fans amperage) to get ~53.6 ohms and 0.46w, which is close to 1/2w. I'll try for 1/2w resistors but if I can't I'll run 2 in serial.
PS: Big noob here, so do I connect the SPST switch to each end of the inline resistor?
ASCII...
I want to make a circuit to switch the fans in my computer from 12v to ~7v (using 2 53.6ohm 1/4W in parallel for each fan) but it has to be controlled using a SPST switch. How can I make the circuit switch from 12v to 7v using only the SPST switch? Thanks!
