    My 23 inch cinema display runs so hot my home office is barely comfortable. Is this normal? Will switching to the newer 27 inch displays help?

    Are you saying that the 23" ACD warms up your room to the point of being uncomfortable? Because chances are your mac puts out way more heat than your display ever would.

    Try turning down the brightness, which should reduce some of the heat generated. The LED cinema displays (24" and 27") tend to run a bit cooler, but can still put out a good bit of heat if you run them at full brightness.

    The 23 Inch ACD is actually the culprit. The Macpro tower puts out some heat but not this much to warm up the whole room to the point of being quite hot. The ACD is way warmer to touch than the heat coming out of the Mac Pro.

    Update - Its first thing in the morning right now - the ACD is cool ( because I just turned it on). But the room is hot!. The Mac Pro machine is always running ... Now what to do?

    The 23" ACD has a maximum power consumption of 90W, the majority of which is transformed to heat, yet some of it is transformed to light, I'd reckon it dissipates about 70W of heat on full brightness.

    The Mac Pro on the other hand can generate up to 500W of heat, depending on your model and configuration. Even the most basic pro dissipates about 150W in idle, so more about double of which the Cinema does.
    Touching the devices isn't an accurate measure for heat dissipation, just look at the power consumptions. A computer transforms pretty much 100% of its power to heat (well a little energy is required to spin drives/fans, but not much).

    And just btw, the 27" has a power consumption of 100W+.

    The 23"ers do get hot to touch after extended periods of time. Simple fact, and you can't do much about it. The 27"er is cooler though.

    The enclosure of the 27" might be cooler (due to larger heat dissipation surface and ventilation slots), does consume more power than the 23", though, and therefore generates more heat (presuming you run it at full brightness). Anandtech measured 100W without charging a notebook, 166W with a notebook attached.

    No dispute on that, but the enclosure is a lot cooler to the touch - can't cook eggs on it!

    But you'd be making the outside world a hotter place!

    Not much you can do short of:
    1.) Turning the Mac Pro off or putting it to sleep during the night
    2.) Getting a computer that uses less electricity and generates less heat, such as the Mac Mini or a laptop.

    Interesting - what is the power consumption of the Imac 27'' compared to the macp pro tower?

    That should give you an idea of how much electricity the new iMac uses. With the display set to sleep and the Mac idling, it uses about 50w.

    A mac Mini on the other hand, would probably use somewhere in the teens.
