Re: Questions about system temps...
I'm not sure about the other temps, but in my opinion the hard drive looks a little bit warm, but it doesn't look too critical to me, you could always go get a HDD cooler if you're worried about your HDD temperature, they're not too expensive. I'd say anything above 60C for a HDD is something to really worry about but I'm not sure. I wish I could help more, someone else could help you better.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
