Left fan running (over) full speed, Right fan not running.
I was wondering if anyone here can help. My Macbook Pro (Early 2011 15”) left fan is always running at over 7000 RPM (out of an apparently maximum 6200), and the right fan rarely comes on. I think the right fan rarely coming on is due to the machine not being under much stress.
According to TG Pro, and other monitoring software, all my temperature sensors are reporting healthy temperatures in the TG green range, and it can’t seem to pick up any hardware issues.
I’ve reset both the SMC and NVRAM several times. I then replaced both fans (as well as clearing out any dust from the vents) but the issue is still there.
I’m now out of ideas. I figure if it was an issue with the temperature sensors or thermal paste, that it would be reflected in TG Pro saying something was running hot?
Is this a good question?
