Is 82 degrees celsius healthy?

My mbp will be in the mid 60's when doing nothing, and 80-100 when playing world of warcraft on the 9400 gpu.
The highest temperature I hit was 81 C and that was only for a few minutes because Spotlight decided it wanted to index while I had Pages, Keynote, Safari, iCal, and iTunes running.
Are you just making these numbers up or what?
Processors can run hotter than that with no harm. It depends on the model as well.
I have a 2.53ghz 13" Pro, and I've hit 93C, but only two or three times while Handbraking a 15 video long queue. Normally I run around 40-50C, but while watching Flash videos can hit 80. My processor is safe for up to 105C according to Intel.
of course cpu's can run as hot as 105C
BUT components around it cannot withstand those temperatures.
some people seem to overlook this, a cpu running at 100+ C will make components around it fail much quicker.
sure you may have a laptop that has run at 100C for 2 years straight....but it WILL reduce the longevity of the components around the cpu.
88C is high....but i would not worry unless you hitting 100+ C constantly.

Indeed the odd spike around 100 C isn't going to be too serious. My MBP jumped to 106 Celcius for the first time ever today due to flash crashing my browser. (OK I did have 10 youtube videos open). Usually it doesn't ever go above the 80's when working out hard.
It always makes me wonder why so many people bother with SMC Fan Control. I have always found Apple's built in system works fine.
No it is not healthy. Normal body temperature is 98.7°F which is about 37 degrees Celsius, I would say you have one hell of a fever.
None of these programs increase the temp of my book... lol iCal.
Looks like lots world of warcraft people here. Anyone attempted Grad Marshall or High Warlord back then?
Wait you're saying Apple's system is fine... yet you had your CPU go up to 106c?
Lol, well it only spiked very briefly at 106 ºC and then came down again. That may or may not be normal, I don't know. I suspect not, but it has only happened once and usually the default Apple fan control is great.
Certainly one thing I have noticed though is just how quickly core CPU temperature can shoot up. If you go from a cold state to doing something intensive I have seen it jump over 40 degrees Celcius in less than 2 minutes.
I have a 13" June 2009 MBP. Whenever I run handbrake this is what I do. I start smcfancontrol and set my fan speed to 5000 rpm. I put my laptop on little wooden blocks so the laptop is above the table by 2.54cm (1 inch). Then I start handbrake. My temperature stays between 75 and 77 C (167 and 171 F). Doing the above I have had handbrake runs of over 12 hours.
It's important to rev up the fans before the machine gets hot. It is easier for the laptop to keep the temps steady than it is for the machine to lower the temp once it gets really hot. Putting the laptop up on blocks lowers my temperature by about 2 C over just letting it sit on the table with that very small air gap between the table and the laptop bottom. It does make a difference.
The other thing to consider is the temperature of the room where you are doing your work. The difference in room temperatures for me in the winter versus summer can be 30 F or about 16 C.

Yes it's normal.
The CPU is generating 35 Watts of heat (half as much as an incandescent lightbulb) in a volume the size of a postage stamp. It gets hot, fast! I'm amazed it takes so long - it shows how good the thermal contact with the heat sink is.
Good for you. Of course you CAN do all this, but you don't NEED to. When I run Handbrake I .... just run Handbrake. CPU temps settle at about 90 C.
Similarly you CAN drive everywhere below 50 mph, your engine will certainly last longer. But you don't NEED to. The engine will still last the useful life of the rest of the car.
