Whenever I try to do an encode of a file or anything that maxes out both processors it cranks the heat up way hotter than I think it should. The norm after less than 20 minutes is 175F (79.444C). Is this normal or should I try and get it replaced?

here's the link to a screen capture

I've noticed that with mine as well. At just a "regular" load it's not hot at all on my lap (thank God), but what do you expect when you max out two cores in a case less than an inch thick? And just remember, the inch apple advertises includes the screen.

My point in another thread... Try putting a 60W light between your legs.. Turn it on.. Enjoy. That's about the same amount of heat that those two cores put out.
 
I'm using coreduotemp to monitor the temperature. And to the other poster, I expect my computer to not reach almost 200F (which is close to the temperature used to boil water, mind you). If I didn't have some protection inbetween my laptop and my lap, I'd probably have burns by now.
 
Notebooks not laptops anymore. Even my P3 Dell got too hot to have on your lap. As for the original post, that does sound hot to me. MacBook here and when I achieve 70C or higher, the fans immediately spin and bring system temperature down to 40/50C, according to CoreTempDuo.
 
Keep in mind that CoreDuoTemp is based on "SpeedIt" that has been proven faulty. It's possible that SpeedIt is causing your fans not to come on.

I would remove it, and the speedit extension, reset your pram and smc, install Hardware Monitor 4 and see what happens.
 
The fans do come on though, even after the fans come on and I would guess the max that they go to, it still stays around 170F (76.667C).
 
Do what I did and buy a laptop cooling stand. $20 buys you a cheap one and it keeps mine under 70F (yes, Fahrenheit, not celcius)
That's not under full load though, I'm talking about when I max out the processors. And I have bought a laptop cooling pad, but it broke before I got to use it with my MBP and now I'm still broke after buying this computer.

how do you check the temperature on a macbook?
