Macbook pro with C2D disable one of two cores?
Hi guys. It's possible to disable one of two cores on my mbp? I want to decrase heat release of my mbp trying to turn of one of cores. Any suggestions?

It won't reduce heat output, but it will cool down the machine faster at the cost of sound and fan life.

You can manually set the fans to run a little higher to keep your machine a little cooler.

You can undervolt and underclock with Coolbook. Google it, very cheap, works amazingly well.

Nope. That's not how it works.
If you have Apple's CHUD tools installed, there was an app that would let you disable a core.
However, I haven't bothered with it since Tiger. They used to have an ftp site set up but now it just takes you to the xcode site, so it's possibly built into the dev tools these days.

(but yeah, it's for testing out the processor and wouldn't do much for heat, really.)
