    Hi,
    I got my iMac 27" in October and more and more lately I've been noticing that along the top it has been very hot to touch (sometimes almost too hot to touch).
    According to a widget it is running at about 49-60 Celsius.
    Is this normal or is there a problem?

    Your Mac is not overheating. The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat (around 100C/212F - 105C/221F, depending on your processor). iStat Pro will give you accurate readings of your temps and fan speeds, among other things.

    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). They will spin faster as needed to keep temps at a safe level.

    These temperatures are normal. If it was overheating, the fans would rev up to remove the extra heat. If the fans could not keep the extra heat out, it would shutdown to prevent damage. The iMac's body is made of aluminum, which conducts heat very well. Apple designed the iMac's body to act as a big passive heat sink. This is why it feel warm, almost hot, to the touch.
