I have a Macbook Air 15". A few days ago, it started running extremely slowly, with the fan at max RPM. I opened Activity Monitor and discovered that I had kernel_task running at about 400% CPU, despite the fact that my computer felt ice cold. Turns out, one of my sensors (the GPU sensor, to be precise) is apparently acting up and reading a good 10 degrees celsius higher than any of the others.
My question is, can I tell the computer to ignore that one sensor? The other sensors are all functioning properly, so I'm not worried about overheating. I just want the machine to stop thinking it needs to compensate for nonexistent heat by slowing me down when I try to use it. A software solution would be preferable, since I'm a relative idiot when it comes to hardware.
