I've had my MacBook since last Christmas, so it's the model from fall 2009. Okay, so my question is, what does this mean for my "battery health": 144 cycles, 88% (4798mAh)? Also, what's the normal/average temp. for a mac to run at? Right now my fans RPM is 1998, and the temps are: HD: Macintosh HD: 110 degrees (fahrenheit) CPU A: 137 Heatsink B: 125 Enclosure bottom: 101 Northbridge 1: 121 HD Bay 1: 110 It's pretty hot in my room right now, and it just finished charging.
