The Definitive eMachines 6805 Interior Slideshow...
I did some modding to the interior of my 6805. Deciding that I hated the pathetic aluminum heat spreader on the VPU from the factory, I created my own copper monstrosity. Several people have emailed me requestion some photos, so here they are..
Here is a photo from Anandtech from his review of the Voodoo Envy M:860 which happens to be idential on the inside to the 6805. You can see the sad little aluminum plate on the GPU to the right of the fan assembly. It's roughly 1mm thick, and 6 cm x 4 cm size. Needless to say, it's there's not a lot of surface area on this tiny, flat, and small thing. Also, it's held on with crappy thermal tape basically.
My first fix was to use this extremely low profile aluminum northbridge heatsink. It improved things a bit, but it was still limited in size and usefulness. I used generic silicon paste to 'attach' it. With the pressure of the fan assembly holding it in place very effectively.
I took off the heatspreader that came with the machine and took some photos of what's underneath.
So, I had a small 1U server copper cooler made by Cooljag/Dynatron on hand to mess with. So I made a rough template and got out the dremel and spent ~4 hours grinding and cutting.

How incredibly rough looking, eh? Well, dremeling a block of copper like this is a real challenge. I was wishing I had a table grinder or something, but alas, I wasn't spending that kind of money on this project
I used Arctic Silver 2 Thermal Paste between the copper beast and the VPU. This is about as good as you can get. The copper beast gets just as hot as the original heatspreader, meaning the thermal connection between the VPU and it is quite good, considering the massive increase in surface area and thermal conductivity between copper/aluminum.
A little too ghetto-rigged for ya? NAH!
With this, not only is the VPU significantly better cooled, but I also can run it at 445/230 in games and not get artifacts. That's up from 420 - I got an additional 25MHz. I was more concerned with the heat output at 420 with that little aluminum thing. I just wanted to cool it down more. But, additional headroom is nice too!
