    it would be helpful if you had a temperature monitoring program and told us the various values

    but the back of the iMac does indeed get hot to the touch under normal use

    Use iStat Pro to monitor the temperatures and fan speeds your iMac is producing. If you want more feedback, report the values here and don't forget to add the temperature scale (Celsius, Kelvin and that other one without the 451 following it).

    Suggest downloading / installing iStat Nano (widget) and tell us its many different temp readings. re:

    IMO.... Temps within 60C range is hot. 70C is "super hot" and 80C is way "too hot". Fans run full RPM at 83+ temps. If wondering, my iMac 21.5" comfortable runs within 25 - 50 C range. Mostly within 35 - 48 C range - for my general home user tasks.

    thanks, i'll download the widget

    by chance, does ram have anything to do with heat generation?
    i just installed 4 gigs of ram today bringing my imac up to 8

    i mention this because i've never noticed the fan noise before
    until today, which is what prompted me to touch the back
