Hi,
the same circuit should also work with 5V. Have you tried it? Normally it should work alright with the same MOSFET. Let me know if it doesn't.
bye,

well... it doesn't actually. we've tried, the fan won't start spinning. I've heated up the NTC a little, but no luck. Same circuit works on 12 volts, and de (5v) fan itself works normal when connected directly to the (5v) power. |

oh, forgot to post about the solution. The solution was to go get new parts. Apparently the variable 10K resistor was a little off and would have required me to screw it over the limit to get the right setting.
With another version of the same the circuit everything worked just fine on 5 volts. |
