  This may seem different, but you could try and adapt this solution to suit your / a notebook.

Russian engineering at it's finest, Dave!

Now my Hear sink is dust-free, i have a coolpad under my notebook (which just helps very little, as the downside of the notebook has not many air cirkulation slits) and reduced frequencies of the main components (CPU: 1833-->1200, GPU: 400-->250, gfx-mem: 450-->350). Result: 67°C CPU-temperature when playing FleetOps (still fluently), so it fullfills the purpose.

I'm not happy with the current solution, so I'm tankful for any suggestion.

I use ATI-Tool for the clock-changes. I noticed something strange. When i underclock the GPU and then start a game - as it changes video mode - the orignal clock for the GPU is being restored. If i then enter the desired frequencies again, they are kept. Any ideas why that happens, and how it can be changed?

Thanks

you need to make the clock changes in the Bios

That's essentially what he's doing. Some manufacturers release utilities which allow you to do this stuff on the fly from within Windows. The BIOS, or perhaps the utility, may be keeping seperate settings for windowed and fullscreen modes

That's actually pretty ingenious. It's not just blowing the air away from the computer, it's taking it and dumping it far away. The only downside is the PC has to be next to a window. I'm not sure if this idea ports too well to laptops for a number of reasons. 1) I requires that the vent be placed directly over the fan itself, not just a vent, to achieve proper air flow. 2) Laptop's don't work very well without their cases (they usually fall apart ) 3) Laptop fans are usually placed so that they push air across the heat sink rather than pull it away. Or to put it another way, they are intake fans, not output fans. 4) Laptops usually have their fans on the bottom or the back. In the case of the former a vent would interfere with placing it on a desk; in the later case there is very little mounting space.

Just some things to consider, granted you could still try.

I like how now, the ad banner at the top of the page is showing ads for notebook coolers.

well, BIOS does not keep seperate settings for windowed and fullscreen modes, that is only with the utilities. So u got the settings nailed down if you set it in Bios aslong u dont run this utility.

The only catch is this: some (read: most) laptops, especially proprietary ones, don't let you change clock speeds in the BIOS. So the only way to do it may be through the utility. *shrug*
