    Hey,

    I've got a feeling that my Macbook Pro 15 (mid 2012) has been running a lot hotter lately.

    When I check the activity monitor, nothing seems out of normal.
    And the fans are spinning only when I do video rendering, 4k video playback or have it laying on a bed - all of these make sense.

    The CPU Core Temp. is running around 65C - is this okey or too hot ?

    Before doing any hard resets, is there anything else I can do to further investigate / solve this issue ?

    Cheers!

    65'c is perfectly normal. It won't shut down until 105'c, and usually runs about 50'c.

    There is no issue. Ignore those temperature monitors which just seem to make people worry, and instead worry if it starts to shut down when you turn it on.

    If it's idling at about 65 °C, maybe it's just too dusty.

    Take of the bottom cover and clean out the dust from the heatsinks and fans. That should help quite a bit; especially if it has never been done before.

    Same here. My 2012 rMBP has run hot ever since the logic board was replaced last year. The CPU in mine is running up to around 90 according to iStat. I used a thermometer to measure the temperature on the section above the keyboard and it measured 47C/116F.

    ok, great. Thanks for the tips.
    Never opened up a Mac before, but I'll give it a go.

    You'll need a pentalobe screwdriver head to open the device. Cleaning dust is easy. I've never attempted to check heatsink or add thermal paste but iFixit is a useful resource.
