Alright, this is starting to bother me to no end. I've got a 14" iBook G4, whose year-old hard drive died about a month ago. It was probably on the verge of dying for a while (I wasn't the primary user of it then and was only told about the "strange clicky noises and freezing up" months after it started), but finally kicked it a few days after it was upgraded to Tiger. I replaced the old 60gb one with an 80gb with no problems. Ever since then, though, it's been getting pretty toasty and the fan is turning on quite often, which I'm told didn't really happen before. It's still within normal temperature range, but hotter than I'd like, around 63C at times. I'm not running any huge programs, just Adium, iTunes, Quicksilver and Firefox. The vents aren't blocked or anything ; it's sitting on a wooden desk. I can't figure out what the problem is, or even if there is one, but I just don't want anything else to go wrong. I still don't know what caused the hard drive to crap out, so I'm super paranoid. Advice and words of comfort greatly appreciated.
