    Well its summer and my mac gets very hot on the back. This may be due to the heat 35C, but it also happens on cool days. When it does get very hot I just shut the system down. My question is how hot is too hot and what is the best way to monitor this?

    iStat Pro to monitor the heat.
    CPU and GPU temperatures of 80° C are quite normal, the HDD shouldn't go over 55-60° C.

    Btw, the aluminium back works as heat dissipator, therefore it being hot is quite okay. The heat has to go somewhere.

    Computers get hot, and the iMac tends to compound the perception of it, as the case is aluminum and acts as a heatsink, which gets pretty hot. You can download iStat pro if you like to keep an eye on temps, but you really shouldn't have to worry about it. Computer components can withstand some pretty high temps (often up to ~100-105C for CPU/GPU). If it thinks it's getting too hot, it will spin up the fans and cool itself off.

    You've nothing to worry about your iMac. You can monitor its temperature to be safe, but there have been hundreds of people posting the same exact topics worrying about their iMacs because the aluminum got hot on the top/back, which is right above the exhaust. Aluminum conducts heat well, and acts as a secondary heat sink to the computer's components, so it's all normal activity.
