    HI evreybody, i've bough a MBP retina Display 13' with IntelCorei5 2.6ghz and 16GB of RAM.T
    When system is idle or under low usage i get the CPU CORE 1 DTS temperature 36(celsius) CPU CORE 2 DTS 38 (celsius) CPU DIE Digital 41 (celsius) and CPU Proximity 38 (celsius). But when i use a program called GNS3 (for emulating Cisco Routers) after few secs i get 96 7 96 98 75 repsectively the CPU COre 1, CPU COre 2 , CPU DIe Digital and CPU proximity.. I don't know what to think..Am i damaging my notebok or is it faulty? Are theese temps trustworhty or i don't have to worry? I've used the program iStat menus Pro.

    Your temps are perfectly normal.

    The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (Source: Intel)
    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.
    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.
    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis), or 1200 for the newest MBAs. Older iMacs have 3 fans with minimum speeds in the 800-1200 range, while the newest iMacs have a single fan, spinning at a minimum of about 1400 rpm. They will spin faster as needed to keep temps at a safe level. If your fans are spinning up without increased heat, try resetting the SMC. (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)
    The intake and exhaust vents are in the back of the computer near the hinge on all notebooks in the MacBook line (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best. For Flash-related issues:

    Thanks for your answer! I was wondering that if using intensive CPU software i could cause a damage in my CPU and notebook..When macbook it's in idle 1/2% CPU usage in total i get 46 49 50 48 temperatures and i think they are normal..Yes the program it's very CPU intensive (297% CPU usage) but even with a high and intensive use are they normal? Am i damaging something using that program? When i'm in idle the fans are at 1278/1300 rpm, when temps get the highest they are 5400 rpm and maybe more. So the fans are working , i hope i'm not damaging my new notebook..:D ps: this happens also with "innocent" software like a game e.g .g Civilization V

    As I stated in my earlier post, no you can't damage your CPU or notebook, because the CPU will automatically shutdown before damage occurs.
