    hello there,

    My macbook pro 13" 2009 (5,5) looked like it had temperature issues. Fan didn't go too high though, but idle temperature is around 80ºC, just browsing the web, and fan at only 2000rpm. I changed the thermal paste and cleaned the fan, which had quite a lot of dust acummulated.

    After done all this, temperatures are exactly the same, if not a 2-5 ºC higher... Is this normal? I used artec MX-4 thermal paste. Please let me know your thoughts. I check the temperature with iStats, and wen opening lots of heavy ups it can get 102ºC easily...

    Check Activity Monitor to see if there is a process that is causing the high temps. Be sure to check "All Processes" and not just "My Processes".

    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). iMacs have 3 fans with minimum speeds in the 800-1200 range. 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 Mac notebooks (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.

    thanks mate, I already knew all that, I have researched a lot...

    It was the ********g Tuxera ntfs processes that were overheating my machine. Now it goes about 10-15ºC lower than this afternoon. Awesome!!!

    It goes around just 60ºC working on the bed. In a flat surface must be below 60ºC. I can't remember when this laptop was so cold!!!! I´m very happy.
