here is something which has helped a lot.

if that doesnt work try this link http://www.targus.com/au/accessories_workspace.asp

the fans are not loud and it prevents the cpu fan going into overdrive

i have tryed it & it does help a little .
the most amazing stuff i have done to cool the cpu is to underclock .
i have tryed it on a athlon from 1.6 to 1.2 & the result was amazing .i couldn t crash the pc , but i am not sure if its possible on a laptop.

how do you do that? do you miss the performance?

the main way to do it is to change the multipliers , its very simple if you have a brain , remember that overclocking reduce the life of you cpu .
but underclocking allows you to have a more cool/silent computer .
most of laptops have underclocked cpus because of the shit fans instaled.
to explain it fully would take me ages .
it all depend of your motherboard & you need a spare software to do that as well . i have never tried it on a laptop but i presume that because laptops are already underclocked there is a possibility to do it . a few weeks ago i started building a clone laptop but i haven t got to the stage of cpu setups yet .ill tell you more wheen i get to the stage.

for the performance , yes you miss a few vsts but it run so smooth that when it s really warm , the computer don t crash & you can switch of your fan when you record without really damaging the cpu.

try this links for explanation about overclocking & underclocking .

It varies from laptop to laptop, but your CPU has to support processor frequency scaling first (most modern ones do). On a mac, you can do it in system preferences under energy saver. Some PC's also let you do this from within the windows control panel. Most laptops won't let you arbitrarily tweak your CPU speed settings, but a lot of them will allow you to modify the settings to conserve energy. In my experience, most of the laptops I've used take an external power source to mean "use all the damn energy you want", so you'll probably get a lot less heat if you run off of the batteries.

I would ignore spiderprod's post if I were you (no offense, man), as he seems to be talking mostly about desktop hardware. You'll find that not a lot of laptops have hardware jumpers for CPU frequency settings iirc, mostly because PC laptop manufacturers don't expect end users to open up the cases on their own. Thus, the CPU settings are usually found in the BIOS menu when you boot your machine up... next time you start your laptop up, go into this menu and look around, as you'll probably find some energy settings in there.

As far as performance hits go, it varies from laptop to laptop, too. My old acer laptop ran atrociously slow when I turned frequency scaling on, whereas my mac doesn't really hurt that much. I've also used other PC laptops that didn't have a tremendously noticeable performance loss when scaling was turned on. Fundamentally, you are sacraficing performance for cooling, so you can't have your cake and eat it, too.

like i said i ve never done it on a laptop , but i presume the whole process depends on the motherboard so is not that different from desktop PCs as long as there is jumpers to allow it .
have you ever tryed to change clock speed effectively from the bios on an athlon laptop ? by experience i have never been able to change the clock speed directly from the bios on a laptop ,that would be a dream for me,imagine you can choose the clock speed when you switch on your pc.

the dream would be to have a knob you can twist on the side of the pc that let you change the clock speed live (like fan controlers).

i've used a little usb fan pointed at the machine to cool it down. it's kinda loud, but it gets the job done.

I juz got a brand new laptop cooling fan! It's called X-Cool & you can actually adjust tyhe fan speed!!!! Now that's COOL!! It also looks better than my previous fan(by Mac Mice)!! It's available in two colors: SILVER & SILVER/BLACK.
