I have been gaming a lot recently on my 2010 13" MBP, (GTAIV). I started experimenting with software overclocking the GPU. I also, of course, am using a number of programs to monitor temperatures and control the fan. In talking with my friends (who are all PC guys and rag on me for my MBP all the time), I've gotten really nervous about the CPU & GPU temps I'm getting. During gaming my GPU temp would get up to 91c. It seemed to stabilize there and even with my fans forced to run at full blast I couldn't get it any lower. My friends told me that was stupid hot and that I should check and make sure I haven't turned my thermal paste to dust. So I checked my thermal paste last night (it actually was fine), but I replaced it anyway with Antec Formula 7 Nano Diamond. Since doing this my GPU only gets up to 82c or so. Pretty sweet to get a 10c drop. My buddies still think this is way to hot. But it really doesn't get hot to the touch at all.
So question one is, why does an MBP seem peachy with what PC users think is damaging heat? I mean, these guys think my laptop should be soup, and I'm like, nah -it's cool.
Anyway, the real question in this thread is this: when I had the laptop apart to redo the thermal paste, I noticed these little pins that poke out of the logic board in several places. A few of them over where the ports are, but one that's just kind of in the middle. They are pins that act in a way sort of like the pins in your mag-safe adapter, in that you can poke them and they give way. I wonder what those are? Are they for grounding to the aluminum case? Some kind of heat dispersion?
