[QUOTE="6string, post: 1018594, member: 120039"] Nice one TattooedMac! +1 for the sticky. Now for my 2cents :) .....A couple of notes to add other than typos :P The climate (room temperature, humidity, airflow, etc) will effect the operating temp as well. When I lived down south, and woke my Mac out of sleep in the mornings, it used to sit on 30-35˚C, and since I moved up north to a warmer climate, it now wakes out of sleep on 44-55˚C (and yes, all the operating temps are accordingly higher). Also, the built in Fail Safe that will shut down your machine when it reaches a certain temp, is dependent on the machine and it's specs, so although the figure may be around 204ºF (95c), it is just an approximate figure. PPC, intel CD, intel C2D, Logic board components, etc, are all factors that will determine what the Fail Safe temps are set to for the individual machine. In my Santa Rosa (late 07) 2.2GHz C2D MB, the shut down temp is higher, but I am yet to see how much higher, as I have only had it go up to 208.4˚F (98˚C) without shutting down. In saying this, it is also dependent on how long it sits on a high temp before it will cause damage, and therefor how long before it shuts down. End of the day, if your Mac is not shutting down, then there is no need for concern! I think that the worst thing that we can do is to install SMC or any similar app if we are constantly going to be looking at the temp and fan speed and getting nervous every time the temp increases or the fan starts spinning fast. I have it installed to see how hot things are getting when I am on Skype video calls (CPU SUCKER), so I know to increase the fan speed once things get hot unless I intend to end the Skype call shortly. Otherwise, I run it with the fan at the minimum 1700rpm (default), allowing the MB to function as it normally would. [/QUOTE]
