I've been looking around on DX and noticed a number of "Thermal Grease" Products.If a Layer of this was applied on the processor, would it act as a heatsink, and reduce how much the processor overheats?http://www.dealextreme.com/details.dx/sku.9339http://www.dealextreme.com/details.dx/sku.22511http://www.dealextreme.com/details.dx/sku.22510

I'm also guessing something like this won't work:http://www.dealextreme.com/details.dx/sku.35816

It is not the processor... the heat comes from the ralink usb wireless card.. try to disable it and feel the breeze

[/quote]You're right, the wifi DOES generate a lot of heat. But I also noticed that with mine, the processor generated a lot of heat as well. With my EKEN disassembled, the processor was often too warm to comfortably touch within a few moments. Same with the wifi card.I tried a few different things to deal with the heat. The most effective was to tape mulitple layers of aluminum tape to the inside of the case above the processor. With the tape thick enough and the case closed, the tape contacted the cpu and acted as heat sink. Of course I made sure that the tape didn't come in contact with anything carrying current. That would have been bad.

I found other chips very cooler than this.. ???However, did you noticed that even in standby, the cpu remains hot?? this means we have no power management and no real suspension there

bad bad bad

(enabling compcache, setting real standby if hardware permits) meanwhile I'm looking to make a script for auto wi-fi suspension when idle ... it's damn difficult cause Android is linux but not that linux we get around last years

bad bad bad[/quote]Same reason as always, I bet - it was cheap. Considering these things cost $100US, something had to give. Like the wifi, the napkin effect on the screen, the rough around the edges android release, etc...

I think that if it were not so impossible, we would have it already.
