I have a fan with a PWM control input wire on the fan. Using anything with an open-collector and reasonable amount of source/sink current (cant find a spec) can drive this control signal. Right now I have 2 fans pwm signal powered from 1 logic buffer (schmitt). Is that bad form? should I instead of have 1 signal on 1 buffer?
Its the same PWM signal to both fans, thats why i thought 1 would be ok.
