    Would someone be kind enough to post here the maximum CPU temperature under full CPU load and Fanspeed?
    Would love to compare this fact with the i7.

    Skylake I5 3.3GHz (6600) CPU temp and Fanspeed vs i7 4.0GHz (6700K)

    Not sure about the maximum temp that they get on either of the iMacs, but I can advise that the TJ max on the i5-6600 is 100C, and the i7-6700K is 105C. (Depending on which source, some say the i5 is also 105C.)

    But at any rate even if the CPU is getting around 95C it won't do any damage. If it approaches 100C the CPU will throttle to prevent overheating, which naturally will slow down CPU performance but won't shut the computer down.

    Which model do you have and what temps do they hit under CPU load?

    Is it an standard on Intel chips to shut down at 100c?

    I have an iMac i7 + M395 and want to compare it with a 3.3GHz i5 (6600 without the K)
    i5 (6600 - TDP 65watt) vs i7 (6007k - TDP 95watt)

    My iMac fan speed is/remains at maximum fullSpeed, CPU at +/- 95°C
    Would like to see a picture of the i5 iMac under full load as compared to the i7 iMac.
