I have a 2020 13 inch MacBook Pro. I physically can see that it has a left & right set of fans on the machine, but I notice that the only fans that ever run are the right set. How can I fix this? I can't seem to find a solution, and the only major thing I've tried is resetting the PRAM (although, I'm still not certain if I did it correctly, since I can't notice any major changes on my machine).
