Good GPU & CPU temperatures?

[zd30]

Whats considered a reasonable temperature for gpus and cpus?
my gpu stays at like 30-35° when idle and the cpu varies from 35-45° when idle.
and when Im gaming the gpu gets up to 60-65° and the cpu is similar but a little higher, depending on the game.

ive been running some games like farcry 3 and metro last light on max settings and the gpu temp gets up to 70° but haven't seen it go over.

i was just wondering are these temperatures normal or is this too hot and should i turn up the fans or something?

thanks!

It depends on the CPU and GPU some run hotter than others. For instance my I7 920 will idle around 40c and run maxed at around 73c. While my gt 430 doesn't get as hot idle at 25c maxed at aroound 40c. (It isn't all that powerful to begin with though)
