Hello everyone,
i will skip directly to what i need.
I have 5 pieces of 12 volt 12cm FANs with 0.23A draw each. They are 3 pin fans. I need to have some sort of control for rpm of those fans. Starting voltage of those fans is 5V. the control should be 1 centralized for all 5 fans.
I have found designs on web but they are either controls for one fan only or separate control for each fan.
I am not that skilled in electronics design so i need some guidance. I solder frequently so that wont be a problem.
Is there anyone who can point me to some , or make some design for me ?
The whole thing should be as small and simple as possible. I need to feed power into it with 5 separate lines (each for one fan, plugged into MB with 3pin male fan connector) and the output should be 5 female 3pin fan connectors. I still need to feed back the rpm readings from fans to motherboard.
if thats too much, what is the simplest way to decrease the voltage on each of those power lines to lets say 6 volts ?
i know it can be done using just an inline cca 50 Ohm át least 2W resistor, but thats a little dirty solution to me.
