Hello guys,

In an aluminum unibody MBP 15" I get these temperatures... just turning it on

Is this OK?

Do you have your GPU activated? That will cause a bit more heat.

But the temps you show are fine. You are just using the machine for its intended purpose, is all.

How can I check if the GPU is activated?... and what is the use of it?

Thanks!

Graphics Processor. Click on :apple:->System Preferences -> Energy Saver (the light bulb). On the resulting screen, do you see option for:

Graphics: Better Battery Life
Higher Performance

And if so, which is checked?

I have High Performance checked

There you are, then. High Performance activates and utilizes the auxiliary graphics card, which is a good bit more powerful than the standard one on the motherboard. Being more powerful, it uses considerably more power, produces more heat... and renders images with far greater depth, speed, etc.

Try to set it to Better Battery. You will have to log out then back in. See if you really notice any difference on screen. I very seldom activate the GPU, only when I *need* it. For most mundane chores, it's off. That will lower your heat a good bit. Make the battery last a lot longer, too...:D

Either way, your temps are within normal range. it's all good.

Yeap... temps going down since I change it to better battery life. I though I could use the extra graphic power since I have the MBP connected to a Led Cinema Display. The main thing I use the computer is for photography... but today is just Internet browsing...

thanks for the info
 
Monitoring your temps is only so useful really. If any of those sensors detect a dangerous temperature, your machine will immediately shut itself down as a safety measure. That's when you know you have a problem. :)

No worries. Fire up the GPU when you crunch some hi-res photos, and crank it back down when you just surf.

It's still awesome, tho, ain't it?

Yes it is... is like hiting the nitro in a car when you need that extra horse power...
