Can I connect 5V DC Fan directly to ODrive S1 5V Output

Since the Odrive S1 doesn’t have a 12v output fan output I’m thinking of connecting a 5V fan to it. I’ll be running it continuously so no fan control needed. One problem however is the current , most of the fans I have pull 0.2A. Will that be okay?

I’m afraid not, the 5V outputs on the S1 have a combined max draw of 150mA. These outputs are mostly intended for the encoder(s) and are not designed to power a fan. Are you using a heat spreader or a heatsink with your S1? You could always power a fan from a different source.
