people are hesitant to play around with the heat spreader because they are correct in that the air around the heat spreader isn't really moving, and it can only absorb so much heat and transfer that heat to the keyboard and out of the machine.
Increasing the surface area contacting this air via a more proper heatsink would not change this. Of course, this is assuming that the air to keyboard transfer is more restrictive than the IC to heatspreader to air transfer.
Now, either way, none of this increase in surface area matters if the ambient temp of the air can't be kept low by removing the hot air or better transferring the heat from the hot air to outside of the netbook.
This air doesn't have to move very fast at all in order to be a significant improvement over stock. Blower fans exist (like those i linked) that are fairly thin. Talking 3mm in height.
For the price, they are the best option. If price wasn't a factor, then i would say the best option would be piezoelectric fans. At ~100 bucks a pop, these guys can be made very small, push a significant amount of air and are totally silent, solid state, and run on nearly no power.
I have two goals when i get the stupid thing (damn dell takes forever to send a netbook).
1. Upgrade cooling to handle overclocking the gpu and cpu. I want to go to at least 1.8Ghz cpu and whatever gmabooster will let me get away with on the gpu. After i measure the clearance between the mobo and keyboard and chips and keyboard and find that it is enough room, i'll get those heatsinks i posted and then get the largest 3mm high blower that can fit. Larger means quieter.
2. Using a usb to pata/sata bridge adapter cord, I plan on disconnecting the usb pins to the wwan pcie connector and running wires to the stripped down usb-ata bridge chip. Then running the pata wires from the bridge to the appropriate pins on the wwan's pcie connector (disconnecting those pins from the mobo if necessary).
After running power lines, i should be left with a mini pcie slot that matches the main ssd
pcie slot. Then when i upgrade my ssd
, i can simply demote my primary ssd
to the secondary wwan ssd
slot and still make use of it. It'll be over usb instead of pcie, but i should still get about 80%+ of native performance
