One of my fans does not run.
Using iStat pro I discovered that my left fan is not working and the temps were running high. I then installed SMC Fan Control to beef up the other fan. I also took out my battery. That has the machine running cooler, but I need to fix this.
How can I know if I should just replace the fan or if something else is making it not run? I figure it is not a sensor problem since SMC cannot make the fan run either.
Is this a good question?
