u must live somewhere cold or ur house is cold cause mine is always in the low to mid 50's

Nope - 95C is where you have to start worrying... cuz if it evaporates water in the air and that water turns to steam, it can play havoc with your logic board... we know the boiling point is 100C - but 95 is the REDLINE - after all, why take chances??
as long as you're under that, you're good.
but DO download SMC FanControl and use it to cool off ur MB.
So you think i will be all-right? I'm not to sure about smcfancontrol is it safe to use it, it can't hurt the computer in anyway?
It is safe. I have smcFanControl running since I got my MacBook, and have it set to 3600rpm.
The program sets the fan to run at a higher speed than the factory settings. When the CPU temperature rises above the threshold for a given fan speed, then the fan controller will spin the fan faster than the speed you have set. So it's impossible to set the fan speed to low and overheat your Mac.
You don't suppose that Apple wants us to purchase a Mac Pro for "serious computing" do you? (No sarcasm).
You know, I have had plenty of folks literally get angry at me for telling them to use smcFanControl. They claim Apple wouldn't value quietness over cooling...Ohhh really? My iMac is not whisper quiet anymore since I upped the CPU fan to 2500 RPM, but it keeps the darned thing from getting "surface of the sun" hot after playing UT3
. It hovers around 88-93 degrees F while word processing/surfing, before I upped the RPM it was at least 10 degree warmer.
i'm on a macbook and smcFanControl says its not supported on launch, but the readme says it is. anyone else getting this?
Not to hijack this thread.....but my imac power supply get's REALLY WARM, yet my AL imac's fans never increase speed....they stay at a constant 1200 rpm for HDD and CPU, and 800 RPM for the Optical drive. Is this normal behavior??
These CPU temps that you guys are saying are normal, are actually quite crazy and way too high. I have a white MacBook 2.1Ghz on the way, and I have to say I'm not happy to be reading this. How involved is it to apply new thermal paste like ArticSilver to a MacBook CPU, and does it invalidate your warranty?
I had been planning to buy a MacBook for work and school, and finally decided last week that for the hardware that you get, it just isn't worth the price (as cool as OSX is.) I ended up buying an Acer instead, with better hardware specs other than a slightly slower AMD dual core, for less than half the price. It runs 41C on low power stuff and barely into the 60s under a load -- which is what I would expect. High 80s and 90s is WAY to high for a CPU to be running. Yes, it can handle it for a time, but it shouldn't have to.
So the day after I bought my Acer laptop, work told me they were thinking about buying me a MacBook to do some stuff on, and last night my boss said he ordered it. They're gonna load some software on it and then ship it to me. So now I'm kind of torn, and reading this about the CPU temps sure doesn't help.
BTW, I also have a Mini (that I'm VNC-ing into from this Acer) and an 8G Touch, so don't think I'm knocking Macs.

1. I think it does invalidate your warranty. Hopefully others will chime in.
2. The temps are normal depending on what they are doing at that time and the Mac can easily take it. I talked to a tech at Apple and they said it was normal depending on what apps you are doing and how many you are doing at the same time.
3. I think the price is well worth it. I would like for it to be cheaper, but I would like everything to be cheaper. If you want the best you pay a premium. Acer is.......well. Enjoy it.
Changing the thermal paste to Arctic will certainly invalidate the warranty and you won't see much of an improvement (like 2 or 3C). Most of the thermal paste that is applied on the MacBook processor in the factory is squeezed out by the clamping of the heatsink. What little paste that is left between the processor and the heatsink is probably slightly too thick for efficient cooling but does not explain cpu temps that are 80 and 90 degrees C.
I have a 2.4 Penryn and have seen 96 degrees C (205F) on iStat with the fans running flat out. General opinion is that Penryn's run cooler than earlier MacBooks !!

Only two symptoms of overheating Macs...
...these are:
Don't waste your time worrying about temps (they're an arbitrary figure to people like you and I). Only Intel know how high these can work safely, that figure will be over 105C.

...these are:
- The unit has shutdown AND a quick look on the console reports something regarding overheating (i.e. the CPU or MLB have shut down the machine to protect it)
- You are beginning to see video artifacts on the display of a Mac while you are completing something computationally exhaustive

Mmmm, all I know is the temps on this Acer laptop with the AthlonX2 range from 36C to 44C and my fan only comes on every once in a while for about 10 seconds. Otherwise it's silent except for the keys I'm typing.
And on my desktop I take care to keep my temps no higher than about 65C on a full load, running some 3D game like Team Fortress 2. I've had plenty of lockups and sudden reboots when my temps got much higher, like in the high 70s and 80s, before I put arctic silver on the CPU and GPU.
There is just no way anyone should be happy with temps that are literally close to the boiling point of water. Especially not for some device that will be typically sitting on your lap.

interesting info on silicon
It's listed melting point is 1683K 1410°C 2570°F
It's listed boiling point is 2628K 2355°C 4271°F
Should I start to worry when iStat reports cpu temperatures over 1000°C !!!
How accurate are iStat temperatures anyway - on a 2.0Ghz Core Duo MacBook mine used to report Heatsink A at 20°C and seconds later it was 102°C then suddenly back to 2°C. I think I even saw -2°C a few times....
