    Ambient room temp: 74F (roughly 23C)

    Mid-2009 Macbook Pro (17", 2.8GHz, 8GB RAM)

    MBP idle temp: 56C

    MBP load temp (Photoshop and an antivirus scan): 94C

    Are either of those too much?

    I can get the system that hot in OS X 10.6.4 or Windows 7 Pro (64-bit), preferring OS X when possible but temperature is the same on both.

    Thankfully I only use my MBP once per week, for 5 hours, but I'm planning on keeping this for a few years and the thought of thermal death creeps me out...

    Idle temp is fine, the load temp is a little high but nothing to worry about.

    If you are worried about it, download smcfancontrol and turn up the fan speed when you are working it hard.

    Your load temp is perfectly normal if your CPU is at or near 100% load.
    The MBP will stabilise at Tj,max - 10 C, your Tj,max is 105 C so 95 C is the target for the cooling system. It will wiggle about a bit between say 92 and 95 and the fan speed will go up and down to keep it there.

    Intego X6's firewall has gone off on me a couple of times with various intrusion attempts. Not often, but I'm happier leaving it on.

    It's much more than semantics. There's a significant difference between various types of malware. If you prefer to run AV, that's up to you, but don't blame Apple:

    I know of smcfancontrol (it's helped a bit) but it's for OS X only. I also need a Windows equivalent... I've got licenses for some software that runs on Windows but crashes on Mac (e.g. Bryce 3D with certain plug-ins, but any Windows-ported app is more likely to have problems than a native OS X app to begin with...)

    I have heard the fan really speed up around 80C... and it gets loud.

    Excessive heat will lower a CPU's lifespan, never mind other components in the immediate area - that much is inevitable. Never mind instability issues. Apple likes to market itself as being "reliable". So far I'm lucky, but a fellow student who bought the 15" model shortly after I bought mine recently saw his crashing as well. (Which was sad, he went to Apple after being fried by Dell. Literally - overheating problems from Dell as well...)

    And for a $2500 computer, seeing such high heat on a regular basis is not good. Even if the CPU is at 100% load, the temperature is still arguably high.

    I have an extended warranty plan (Best Buy), but for $2500, one should expect Apple to put in a little more time and involvement. (my other laptop, a PC running a 1.7GHz quad i7 and nVidia M320 doesn't get up to 71C under full load...)

    Just as long as my unit doesn't die of thermal death, display weird green and purple lines, or has the same problems I've read from other 17" mid-09 MBP owners will I accept that the warmer temperatures are "normal". The numbers still seem high.

    My 15" C2D idles anywhere around 40C-50C when I'm on a light load using the 9400M, and tends to stick around 50C-55C when I'm using the 9600GT. During heavy use, it idles around 70C. I've never seen it go higher.

    I'm not sure what you think Apple should be doing, exactly. Is your computer actually malfunctioning, or just running warmer than you think it should?

    I have one of these and the fan is often running at 6000+rpm. Even when I start the machine, I can hear the fan and it's running at 2000 rpm or around that speed.

    I expect Apple and Intel know exactly what they are doing. Apple has made millions (tens of millions?) of laptops with the same temperature performance. Intel specifies chips in this way for render farms and server farms. If Intel didn't think the chips would last a very long time at 100% CPU load Tj,max - 10 C they would change their temperature specifications. We don't see many reports of CPU failure on these forums. Far more common is internal power supply failure resulting in inability to charge which I suspect is due to overheating of discrete components in the PSU. You still need a new logic board whether it's a $2 PSU capacitor fails as with a $300 CPU. And yet no one writes blogs, or worries about those though :)

    Your blogger is IMHO wrong. He says "the SMC is not very smart". IMHO the SMC is very smart, it has built in hysteresis to prevent the fans winding up and down at each small spike in CPU load. Fundamentally, the headline in the blog is wrong:- your Mac is not overheating. It remains within Intel specifications, therefore it is not overheating.
