Hey, so recently my fan had given up the ghost, so I bought a new one and installed it. Everything worked fine, until a couple of weeks ago I noticed that again iStat showed 0 rpm. So I opened my Macbook, took the fan out and since I didn’t know what to do, I put it back in. And, voila, it worked again. I had to witness this game a couple times since then, sometimes I just needed to reboot and the fan would start going again, but now it seems it has died, again, eventually. So I’m gonna get a new one of course, but my concern is that the new one also won’t last quite long. So I gotta ask: What keeps killing my fan?
Frankly, I’ve had issues in the past with quite a few of these monitoring apps. I’ve found some don’t report via SMC but by SMART only with the drives. Some have there polling get hung. I’ve found TG Pro has been the most stable and easiest to use. I would recommend you remove the others and give TG Pro a try. While you could still have a fan issue TG Pro offers an effective logging function so you might see a correlation on what is happening when the fan winks out (payed version). As to what to do to fix the fan issue. I’ve encountered odd issues with SMC that you need to reset it. Follow this Apple TN to see if that helps: Reset the System Management Controller (SMC) on your Mac Often I’ve found older SMC temp override software was the issue so do take out any override apps like SMC fan Control (you shouldn’t need them)
