For the sake of anecdote, during an Australian summer my drives can get to 50c, and will usually be around 30c to 40c for the rest of the year.

For fun, my GPU will hover around 50-70c, occasionally hitting 80c. The CPU around 50c, and the rest of the machine is a mystery!

Thanks to some utterly awful cooling my laptop CPU idles at about 70c, peaking in the 80s. I don't know if it's within spec for an i7 or just dumb luck but its still running just fine.
