I bought Dedicated 4020 Cooling Fan for Jetson Nano and after soldering the header , I connected the fan and ran the command “sudo jetson_clocks” but still the fan doesn’t work .
To check the fan I connected it directly to 5V and ground of the 40 pin and it was working fine . Then I checked the voltage on vcc of fan pins and it was fluctuating but the highest voltage was 4.8v
which i think is not enough to run the fan , the TACH pin had constant 4.8 v.
Can someone help me out here I don’t know what the problem is .
