Weird negative temp in istat pro

They are a cheap part, under $15 I think. Apart from the machine not knowing if it is overheating or not, there isn't much impact. You can change it if you want, I know I would especially if I still was in the warranty period.

If you're using a MacBook Pro with both integrated and discrete graphics cards, you can install gfxCardStatus to manually select your other GPU. If that doesn't apply or help, try reinstalling iStat Pro.
I just did a little experiment. Interestingly enough it only shows a negative temp when I'm on the integrated GPU. If I use gfxcardstatus to switch to the discrete gpu, it shows up as a positive value; ~113 degrees F in light use.
Perhaps it only reports on the discrete gpu, and when the integrated GPU is active, it reports that negative value.

Exactly correct, Bozz. This happens within istat where once the dGPU is forced it will display a positive number (actual), once it pushes to integrated again istat doesn't recognize the change and displays an arbitrary number until your machine is re-started.
No shinnanigans save for istat being selective!
