[/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.
[/quote]some heat from the cpu is logical.. what I don't understand is why they used a so hot wireless chipset.. 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[/quote]I have my WiFi disabled most of the time so if it is still the WiFi causing all this heat (I actually burnt myself on it it was that hot) then this is shocking power management. No wonder the battery life is crap.[/quote]I worked before with arm7 boards, and I assure that there is much work to be done once we'll get the source for Eken
(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
