    I just got a 15" macbook pro last week and i've been noticing some issues with heat.

    Whenever I have the magsafe plugged in, the laptop will eventually get very warm (the processor temp reading 170 degrees or so). However, when it's not charging or plugged in, it mostly stays around 120-130. The weird thing is, even if it's not charging and the magsafe is just in, it will still get to those hot temperatures.

    They don't really bother me, but I don't want to damage my laptop, or perhaps it is damaged already.

    So, is this normal or ?

    What are you doing at the time, anything processor intensive?

    No, I'm just using ichat, itunes and perhaps safari. the total %cpu usage is usually around 20%.

    Also, if it makes any differences I plug my charger directly into the wall and I never hear any fans in my macbook

    Sounds like your fans are dead, call Apple or take it in to a store.

    About a week if it needs sent away. Better than having no laptop because it cooked itself.

    Yes, that's too hot.

    Apple has a problem developing efficient cooling systems. It's affected many of their systems from Laptops to the Pro boxes.

    You have two choices. You can purchase a laptop cooling stage or you can install smcFanControl. The smcFanControl is free (donation ware) but will cause dust bunnies to accumulate a little faster.

    Cooling Stages:

    Did you read the thread? It sounds like the fans are dead. At 170º they should be roaring.

    I have hte laptop plugged in right now and am waiting for it to get hot so i can see if the fans are loud enough to hear.

    Do you think if I bring the laptop to an apple store, will they be able to exchange it immediately since i just got it a week ago?

    They might, but chances are they will repair first.

    Yes, I read the thread. He said the fans are moving. So they ain't busted! :D

    It's Apple's fault. This is a common condition! It's the reason smcFanControl was created in the first place actually. :)

    Take the steps prescribed in pittster's link and then install smcFanControl... or get a cooling stage. :)

    He said he can hear something ... processor and HDD both make noise too.

    At 77C? My fans didn't start to come off idle till 85 or so. This seems to be "normal" from what I've been reading. I think Apple went a bit too far to keep fan noise low. I'm using Fan Control now like it a lot. Still think it's a shame that I have to.

    However, for all I know, the machine may be able to handle these temps just fine. But it feels mighty hot to the touch, and for a little bit more fan noise the temps stay quite low.

    I think you're right. I think it's normal - for Apple.

    It is however a little too hot. My laptop runs DVD movies at 32C and idles at between 24C and 27C as an example. Over 50C is dangerous. He said his was usually 48C ~ 54C (120f ~ 130f). The 76C (170f) is REAL cause for concern - but not uncommon for Apple unfortunately. :(

    Indeed, normal for Apple. But not good, and not a good idea. Your temps are pretty nice. I have Fan Control idling at 1800 RPM and the temps are around 39-43. Any climb above that and the fans start to speed up. What a concept! I really don't like how cooling performance is much worse in Bootcamp. Flight Sim X can generate some real heat.

    Apple has problems here, and programs like FanControl and smcFancontrol show that it shouldn't be too hard to fix.

    so i'm unsure of what to do

    Should I just let my laptop go on as normal, getting incredibly hot

    use fan control

    or call Apple and try to have them repair it.

    I would just call Apple, but it seems as if all macbook pros are having this happen, so would they actually repair it or ?

    I thought they will trade it for a new one on spot within 14 days of purchase?

    What laptop do you have that idles between 24C and 27C?! I've had many laptops, from Dell to Acer to IBM and now Apple, and none of them idled below 35C. My current MBP idles in the low 40C and high 30C, and my white MacBook in the high 40C, but I think I may have kinda screwed the MacBook up :p

    Install SMCFanControl to make sure the fans really are working. There is no way SMCFanControl will harm your computer.
