So I just finished making a diy stir plate and everything seems to work great other than the speed of the fan is very weak. The power supply specs are:
Input 100-240V, 0.2A Max
Output 12V, 500mA
I thought in all the research I read that 12V would have been plenty but I don't know that much about electronics. Could this be the cause of the slow speed?
Only thing set up between the supply and the fan is a 25ohm reostat and a rocker switch.
