I can't say for sure with that model, but u can kinda tell the normal temps...at least the difference between cpu and rsx based on the chip size. if the cpu is larger, it's going to give off more heat, so those temps may be normal. u can find the chip size for that model on psdevwiki. I personally have temp thresholds set at 65 degrees C. which is around 150 degrees F I believe. mid to upper 70s is normal for most systems while running a game. I'd be concerned if it hits 80 or more though. I'd suggest having temp thresholds around what I put mine. it might get a little noisy, but u don't want the console to overheat.
