Dear all, My Macbook Pro 13 Mid-2009 has served me (mostly) well for three years now, but the battery ist kaput, and I'm considering pumping a couple of hundred quid into replacing it and upgrading the RAM and Hard Drive so that it may continue to serve me well for a few more years to come. However, before I do that, I'd really like some advice on some temperature control issues - I've seen that they're common but I'd appreciate some help on my specifics. Basically I don't want to drop loads of money on this machine if doing so won't result in any better performance, because of the temperature issues, or worse, if it's going to suffer a heat-death on me in a year or so anyway, like my previous macbook did. So, even completely idle the CPU will sometimes run up to 85/90, with the fans roaring out at 5000rpm just to keep it there. Anything more labour intensive and the fans shoot up to 6000 to keep the CPU at around 100. I tried resetting the SMC, but it has no effect. Not had it shut down on me yet, but that doesn't stop the worry that it might happen soon. So, is it serious, is there anything I can do, and is there any way the upgrades will help? Thanks!
