Hi, my Toshiba p100 laptop is used as a media center, and has the lid closed. I have just cleaned the inside and re applied heatsink. Used normally I have no problem with heat, but since this is placed in a little shelf, and the lid is closed, it produces a lot of heat. I have found it is the graphic card that produces the heat. Can I underclock the Graphic Card? Or increase the Fan speed?

What tools to use?

I am also working on a custom plate with fans mounted to create some air flow around the case, but a force of the nVidia fan to 90% would be awsome!

Greetings!

To underclock (or overclcock) use coolbits-

You can adjust the fan speed as well-

A 'laptop cooler' may help your heat issues as well-

Hope that helps ;)

Not a problem.

BTW, you may have more video stuttering if you underclock the video card, it really depends on what your playing.

2 hints on your fan coolers from a long-time hardware modder-
1- hook up the fans to the USB BEFORE you do the taping, etc. Some fans will not run on 5v, and other fans will run..if you give them a push to get going.
2- see if you can find 92mm/120mm fans (instead of 80mm fans). No only do they move more air, but also in my experience they are slightly more likely to run @ 5v.
