MacBook Pro 9,1 CPU Temperature?

One other thing I forgot to mention. Some people like to use those blue nitrile gloves (I get them at Costco). Particularly for ESD protection, but also to provide clean/oil-free fingers. I keep some in my backpack for work purposes only (dealing with millions of dollars of data center compute and storage gear). For home use, I don't bother. I usually just wash my hands thoroughly before starting.

Up to you if want to go that far or not.

Thanks! I picked some of those up too. Didn't get a chance to work on it last night. Will try to find some time today.

Okay, finally got up the nerve to do this. I applied Gelid GC-Extreme on the CPU and GPU using the supplied spreader. Apple really caked the thermal paste on, but even though I felt I did a better job, there's virtually no difference in the temperature readings. Perhaps I should try the pea or line method.

Voltage fluctuations are normal, and typically vary based on system activity.

Your results aren't too bad, considering the temperature of the air exiting out the back is 2 degrees warmer, and HDD temp is 4 degrees warmer. This suggests that you had more activity happening on your system than when you tested prior to the change. (I was going to suggest that the room was warmer than before, but the palm rest is reading a cooler value than before, which wouldn't make sense if that were the case.)

I would still take the heat sink off and check what happened with the paste when you out everything back together. Since it was your very first time, don't be too surprised if you put too much on.
