MBP running really warm in Windows7

Hi,

I got my new MBP today top end 15" one.

I am currently installing a game in windows. All that is happening is I am posting on here whilst steam downloads something. The bottom of the laptop is ROASTING! on the left hand side, so right on my thigh as i am sitting down. The heat is comparable as to when i used to be playing WoW on my old 13" unibody macbook.

Is it normal for it to be this warm when im not even doing anything intensive?
 
why are you running WoW in windows? It works on OS X too doesn't it?

The high end MBP 15" has a pretty powerful GPU inside so it's not really surprising that it would get pretty hot while playing games.
 
My 15" 2011 does get hot running Win 7 64 bit under bootcamp while playing videos (haven't played any games yet), so I assume it's normal.

I'm not running WoW in windows, the heat is comparable to when i play WoW in OSX.

All i am doing is downloading a game and listening to music on spotify whilst posting here!
 
Well, I couldn't even play games in my 2009 15"mbp (9600m GT). Played really well for a bit then shut down (probably because of overheating). At the end I was struggling to get 15-20 fps on parallels with lowest settings :p (LoL, not WoW)

Quick question: Does the new macbook pro use the intel HD3000 at all in boot camp or is it like the old one which only used the discrete gpu? That kinda sucked...

Cheers thats the same as I am running so it sounds about right! I think on my old mac windows always ran hotter than OSX.

I am about to try a game so will post back if it gets any hotter.

From the heat im guessing it just uses the discrete GPU and not the intel chip at all.
 
Windows does run warmer than OS X, at least on my 2010 13 inch MBP.
BUT, you say you just got it today. Doesn't windows do some sort of indexing thing when it's new, to make searches faster? If that's going on too, it could be causing extra heat.
And I'm assuming you haven't got it sat on a bed or blanket, tiger skin rug, etc

Its just on my lap, no tiger skin rugs in this house haha.

I'm back in OSX now and can feel it cooling down already so yeah, it can just be another thing on my list of reasons why i like OSX better!

Astounded by the sound quality on this compared to my old 2009 13" unibody macbook worlds apart!

What can you expect from something Microsoft made?!

lol...really...
Windows 7 doesn't overheat on laptops that were made to run it. It's because Apple's "amazing" computers can't handle running it.
 
/sigh lots of misinformed fanboys bashing windows

its apples fault it runs hot because they didnt write graphics switching drivers for windows just like previous generations.

you are running the discrete gpu 100% of the time in windows. on the mbp 13" this shouldnt be a problem but nobody will post any damn battery tests on windows for it.

basically apple gimped windows on the macbooks on purpose to make windows look bad.

I bet windows would get better battery life than osx if it had access to the hardware like osx does.
 
In addition to what boonlar mentioned, Windows is also less efficient than OSX and I'm guessing the bootcamp drivers don't manage power as aggressively as OSX. More power usage = more heat output.
 
This is normal (as long as it's not running too hot). I think there are two things at play here:

1. Apple has not developed/included any graphics switching drivers for running Windows on Bootcamp. Therefore, the discrete GPU is always running.

2. Macs are engineered to run OS X optimally, not Windows.

I use LubbosFanControl when running Windows 7 using Bootcamp. I actually find that I need to set the fans to a minimum of 4000rpm if I want to keep the temperatures controlled.
