I have a hp G60-244dx, which features the nVidia GeForce 8200M G graphics chip, and nVidia nForce chipset.

It runs Windows Vista Home Basic.

I don't use this for anything beyond web browsing, email, reading news, etc. No heavy graphics use, no gaming.

Is there a reliable way to underclock the GPU, so as to reduce the overall heat generated by the laptop?

EDIT: I tried nVidia's System Tools, but I could only see how to overclock with that tool. I want to underclock.

Right now I have an idle PC, doing nothing. The nVidia GPU reads 72C (161F), which is extremely hot for doing NOTHING. As a result the laptop's fan is constantly whirring at an audible level. I don't need high performance graphics. I especially don't need the whirring sound. How can I turn it DOWN?!?!!?

I would also consider modifying the DSDT for the ACPI BIOS, but I can't figure out how to do that either.

From Troubleshoot your video card by underclocking :

If you have an NVIDIA card, then you should start with CoolBits because it uses controls provided by NVIDIA. If that doesn't work then you can try PowerStrip. If PowerStrip has problems then you can try RivaTuner.

I've heard good things about overclocking with RivaTuner, maybe it can underclock your GPU for you.

Thinking about it, this is something my work lappy could do with as well (Nvidia NVS 135), I'll try it next time I'm at the machine.

Try going to the Power Settings, and looking at the advanced power settings. There should be options in there to help you out.

I don't have your hardware, but I have a laptop with an Intel and a nVidia gpu, and I was able to turn mine off, and there's a setting for telling the fan how to behave. Whether it should kick up the fan when the GPU is demanded, or whether it should just slow the GPU down. Some other interesting settings too that you might find useful are in there. If you came across a setting that you don't understand and you're afraid to change it, just google it, and you'll find a ton of sites explaining the setting in detail to you.
