(moderation:
I have checked all settings (I think!!) but when i run boinc (with einstein as a proj) my CPU starts heatin up! it shouldnt be doin that because im using my computer and its not supposed to start crunching until 10mins of idle time... whats up??

Couple places to check.
Make sure your preferences are set the way you like on the web under "Your Account".
If they're not, change them.
Look at BOINC manager under the activity menu.
Make sure it's set to run according to preferences.
If it's not change it. If you had to change anything on the web, you need to go to the projects tab, highlight E@H and hit update to force BOINC to communicate with the project servers.
And if things are getting too hot, check for dust, failing fans, etc.

This is a brand new laptop, so there wont be mechanical or other issues like that.
I checked all the settings and they seem correct... i dont get it!

MacBooks tend to run hot even when BOINC is suspended. I know--I've had my lap warmed up many times since I got mine back in June. They run even hotter when the CPUs are heavily used as happens when BOINC is running. The solution I've found is to put my MacBook on a desk and aim a floor fan at it when it's crunching for E@H. That keeps it cool. Or if you want to use it while it's crunching, there are several lap desks that you can get that will keep your lap safe.
Good luck.

The current alpha core client

The current alpha core client in testing right now has the ability to do CPU throttling.
I use that on my laptop.
Works well and it seems like the developers have ironed out the last few bugs with the mechanism.

Another way to throttle a MacBook or MacBook Pro is to change the Energy Saver to "Better Energy Savings." That will rein in the CPUs, so you'll see a difference in compute time when using CPU-intensive applications and should also notice less heat produced. I haven't really played around with that option much besides setting it to "Better Performance" as I have several power-intensive applications. Besides, changing to "Better Energy Savings" will cut into my RAC since it will take longer to crunch work units.

Glad to be back to E@H from my hiatus. I never really got this project off my mind, so I guess I will have to keep crunching here. :-)
I have the same issue with my laptop. About a year ago, I decided to invest a touch in a laptop cooler. Best thing I ever did for crunching with that computer. It cost far less than fifty dollars as I remember, so it wasn't expensive, but it gets rid of the heat lickety split. I use it the minute I get home, and I put them both atop a simple breadboard (about $4!) on the floor where it sits crunching 24/7 when its not being used for class while I'm in college. The extra cooling will no doubt help keep that laptop in great crunching shape for many years. Heat is the enemy of laptops in general because of their undersized fans.

I've never heard of a laptop cooler. What exactly is it and where did you buy it?
RE: RE: Glad to be back

Good question: I hadn't heard of any either until I talked with my computer store. Just do a search for laptop coolers and you will get all the info you need. Essentially, they are external mechanisms that help the cooling fan do its thing: cooling the underside of the laptop. They get rid of the heat and therefore (assumedly) prolong the life of the computer. They usually plug into the laptop from one of the USB ports and so are powered from the computer itself. Think of it as a plastic flat board with a couple of built in fans that carry external air to the underside to help cool it. In terms of noise, by the way, they are almost completely quiet, with only a few decibles of sound: the computer itself will drown out what little sound they make.
BTW, if I had it to do all over again, I would buy one with either three or four fans, but really two is enough. :-) Happy cooling!

They are also sometimes called 'notebook cooling pads' +/- 'USB' too...
Cheers, Mike.

If you can afford it, get a more expensive cooler - especially aluminium. These will draw out more heat and transfer it more easily. However, I'm currently typing on a laptop sitting on top of a plastic cooler with three fans on it.
It helps a bit, but what also helps is the throttling in the latest version (otherwise the CPU tends to overheat and throttle itself).
