I mean I'm getting sweaty just using it on my lap. Do they really generate this much heat or did I get a dud? It's pretty damn warm. What's the best way for me to check actual temperatures to compare with others?
 
are the fans running? I heard they get warm....just not as warm as the memrons
 
My 17" gets hot enough that it is not comfortable to use it on my lap. I think this is why Apple stop referring to them as laptops and now call the MBs and MBPs notebooks.
 
BklynKid , download that widget listed above....if you can report the temps, everyone here will be able to tell you right away if this is normal for it.
 
I know this is unrelated but my 17" g4 got very warm on my lap too so I am kind expecting the heat.....thin laptop made out of aluminum....it kind has to get hot.
 
I agree, it gets very uncomfortable when using the MBP on my lap, sometimes I have to use pillows because it gets so hot.
 
you shouldn't be putting your computer on your lap...it should be used on a hard surface..
 
Ok it was definitely hot than this before but now it's at 52 degrees and Fans are going at about 2000 RPM each (left and right).

I really appreciate the help guys.
 
Thanks cmm26red, I'll check that out in a bit.


davinche, you have a Penryn MPB?
No I have a SR but I've also own two other MBPs and they all ran warm enough to make lap use uncomfortable. I believe the case gets warm as part of the heat dissipation (I think that's the right word), it is by design. I know the Penryn are suppose to run cooler but I don't think cool enough to make you able to keep one on your lap for an extended period of time.
 
Fan rpm is fairly normal - temps (depending on what you are running and what is being measured and what the ambient temperature is) may be a tad high - I'm running 104 F @ 2002 rpm doing web browsing only.
 
I'm running at 139 with fans running at 2000rpm. I'm web surfing, listening to music in iTunes, have mail open, and have Parallels running my XP boot camp partition.
 
Now that I think of it, I was doing DVD-drive intensive things before. First I was installing Windows and then Orange Box (two DVDs and it takes forever). So the DVD drive could be to blame?

In the power options I see three options, Better Energy Saving, Normal and Better Performance. Do these have any significant impact on temperatures (if anyone knows, before I go and try)?
