Hi there,
I have a circuit with four power MOSFETs. Near them (or on the heat sink) is placed a temperature sensor, which detects when the temperature is above a certain level. Now for the tricky bit...
How do a select the right fan/heat sink for the application?
I know the effect of the MOSFETs
I want to calculate the fan flow which is needed to cool down the MOSFETs faster than they heat up, so they don't cook.
