    Hi guys,

    I have few questions. I run a 27 iMac on 10.11.1. It has a 2,7 GHz Intel Core i5.
    I have a question about temperatures. I am playing games on my iMac a lot.
    Sometimes when I play Runescape or HotS, the temperatures are bit high and fans are bit loud.
    It takes some time to cool system down. I know its a old iMac but I love it.
    I have never cleaned him. Should I? and if how so?

    The tempetures are:
    HD: 56 C
    CPU: 50 C
    Ambient 34 C
    GPU: 70 - 72 C when gaming after its about 60 C
    Mem Controller: 56 C
    Optical Drive: 52 C
    Power supply 2: 69 C

    And the CPU fans are usually about 2000 - 3200 rpm (when runescaping)
    The others are 900-1100 rpm
    Can I do something?

    Thanks for the answer.

    Games cause hot, and there's really nothing you can do about it. You're pushing the CPU/GPU to the point where the fans try to keep up and given the thin/closed design of the iMac it struggles.

    Those temperatures are actually pretty low, especially compared to what a notebook can get to. There is not a lot you can do, as you say giving it a clean out may well help and new thermal paste won't hurt either but thats not a job I would relish on an imac.
