Hard Drive Death, Overheating?

[cwesk]

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.

That's normal, don't worry about it. Just for fun though, what brand HD are you using? Is it a 7200rpm family?

iTunes (especially with AirTunes) and Firefox (especially on flash intensive sites) can easily force an iBook well into the 60s. Shouldn't be a problem.

One thing though is that you should get Flashblock to get rid of those annoying flash ads and thus make Firefox a bit less CPU hungry and everything should cool down (into the 50s).

A combination of either heat death and tin whiskers, with HDs adding the dreaded mechanism failures.

Chances are electronics made in the wonderful lead-free days with close packed soldered components will eventually fail due to shorts caused by the tin growing little whiskers across the gaps.
