As some of you may or may not remember, my logic board on my early 2008 MBP went due to the dreaded nVidia 8600GT card on monday. It was diagnosed as such and the local apple stored gladly switched out my logic board with a brand new one. I went there tonight to pick up the machine, I noticed the top case had not been properly clipped back into place, I told the genius, clipped it back on myself, shook hands with the genius and went on my merry way. Here's where it turns sour: First off I notice my pristine MBP is covered in greasy dark smudges, as if the person working on it had motor oil on his hands. I open up the computer from sleep mode, it sounds like a frickin' jet engine, both fans are going nuts at 6000rpm and the computer is at about 30C. I shut it down, reset both the PRAM and SMC, turn it back on, no improvement at all. I pull up iStat and I notice that the CPU temp is not showing, even though it is checked in the preferences. I open up FanControl in the system preferences, not only does the temp read incorrectly, it reads as -128C, yes, MINUS 128C. All the while the fans are blaring at 6000rpm. I close the system preferences, decide to check my e-mail, and get a Kernel Panic instead. Pissed off, I shut down the computer, turn it back on, only to get similar results. Long story short, I'm extremely pissed, and I feel sorry for the fellow that will be getting me tomorrow, he's going to have an earful. Do they even test the machines before they give it back? Surely fans spiking up to max speed on idle is something someone would notice?
