CrazyLexx Posted April 4, 2007 Share Posted April 4, 2007 Hi there folks, I'm currently running Vista Home Premium on a 2,16 GHz C2D MacBook Pro with the latest beta version of the BootCamp driver suite installed on it and all of its components seem to run fairly well. However, my MBP gets quite hot after a short period of time under Vista compared to running comparable applications (mail client & browser) on Mac OS-X. Why is that so and how can I get my MBP to be as cool under Vista as it is running OS-X?! I've already set the fan speed up to 2000rpm and set the Vista power saving features to the highest levels (just like in OS-X)... Since the hardware configuration remains the same, I'm wondering what precisely cause it to heat up in Vista!? Is it just the CPU or even the GPU? Why is it so different on OS-X? Thanks, Tom Link to comment https://www.insanelymac.com/forum/topic/47476-mbp-and-vista-why-much-warmer-than-running-macos-x/ Share on other sites More sharing options...
crocitto49 Posted April 5, 2007 Share Posted April 5, 2007 I have the exact same problem... except I use a MacBook... Vista & windows altogether run so many processes in the background that it just gets the machine running hot... however... Vista won't sleep in my MacBook.. and when i close the lid it just runs hotter and feels like it's burning a hole through my bag :( OS X is just plain and simple a better OS!

Adrian Fogge Posted April 5, 2007 Share Posted April 5, 2007 For the most part, it is because of all the stuff that is turned on by default in Vista. What you can do is go into "msconfig" (type in the "Run" box - Windows+R) and start disabling some of the things under Services that you do not need like Server, Tablet PC Components, Terminal Services, Remote Administration, Windows Sideshow, Windows Sidebar and the like. As far as Vista staying on when you close the lid, it is a power management setting that can be changed. By default it is set to go into standby when the screen closes which happens on both the Macbook and Macbook Pros if you have the drivers installed. ~Adrian Link to comment https://www.insanelymac.com/forum/topic/47476-mbp-and-vista-why-much-warmer-than-running-macos-x/#findComment-340373 Share on other sites More sharing options...
Archvile Posted May 26, 2007 Share Posted May 26, 2007 I'm currently running Vista Home Premium on a 2,16 GHz C2D MacBook Pro with the latest beta version of the BootCamp driver suite installed on it and all of its components seem to run fairly well. However, my MBP gets quite hot after a short period of time under Vista compared to running comparable applications (mail client & browser) on Mac OS-X. I've noticed the same thing on my Macbook (non-pro) running Vista Home Premium. My guess would be the Aero interface (dwm.exe), it's not only a resource hog but also puts your gfx card through the paces (more so than OS X, at least). That, combined with the fact that it has so many more processes running in the background, and it accesses the hard drive almost constantly (mostly due to superfetch), would make sense why it tends to get a little warmer. On the other hand, I haven't experienced *any* problems with Vista whatsoever (no missing drivers, conflicts, etc.). I don't know if I've been lucky, or it just works. It even sleeps just fine on my Mac.

I still don't buy that line of thought. If I don't touch the system and let it stay in an idle mode, the cpu isnt't used for more than somewhat around 3% of it's max power. Same with the GPU: If I don't touch the system, the Aero interface doesn't have to render any news stuff and the system still runs way too hot. My best guess (and observation) so far would be, that the power managing functions under vista aren't supported properly by the BootCamp drivers (yet). No matter how much stuff I actually do on my MBP, both the CPU and GPU seem to constantly run at a maximum performance level.

rollcage Posted May 26, 2007 Share Posted May 26, 2007 It's the same reason your body gets a fever, there's something inside it that shouldn't be and it's trying to kill it. You might want to try going into power settings, advanced, and make sure the min cpu level isn't set to "lava". You could also lower the max cpu level a bit and that might make a difference.
