    Hello.

    I got my iMac about four days ago. and always when I feel it it's very very hot. Even when I'm just browsing the internet. For example, Currently only Adium and Google Chrome are open and the temperatures by iStat are:
    HD 49C
    CPU 49C
    Ambient 37C
    GPU Diode 58C
    Power Supply 67C

    Is it fine? and if not, what can I do?
    ( the iMac isn't blocked on the behind of it, so it can't be the reason ).

    Thank you very much! :)

    Those temperatures are normal. iMacs feel hot because they are made from aluminum, which conducts heat very well. Its nothing to be afraid of.

    Those are perfectly acceptable temperatures, especially in a hot climate. The back is made of aluminium, thus it feels hotter, as it radiates the heat better.
    You can also check Activity Monitor for CPU process, like shown below.

    ______________________________________________________
    Have a look at Activity Monitor (Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.
    Also check the "System Memory" tab to see what your "Page ins:", "Page outs:" and "Swap used:" are.

    image below uses sorting by CPU as an example

    Its quite normal for that to be wrong. My Mini says the ambient temp is 122F, when its really 75F.

    Smc fan control

    I use http://www.macupdate.com/app/mac/23049/smcfancontrol

    (SMC Fan control)

    I have presets for all of the fans. When it first runs, it reads the current fan speed as default.

    You can then preset different speeds. I have one for work, and it accelerates the fan speed by about 20%.

    I have another setting that maxes out all of the fans. Makes the iMac sound like a vacuum cleaner! But it works, drops the temps in a hurry.

    Humidity might play a factor in accurate ambient temps.
