Your n900 is heating because,if you dont do the following steps, the system sets the CPU to its maximum (1150 mhz): 1) go to /system/etc/ 2) search for files oc-profile-***-***.conf 3) rename one of these in "power.conf" Personally I've renamed "oc-profile-250-500.conf" and increased by leafpad the 500 limit to 750 limit and is perfect Note that, everytime you will use wifi in nitdroid, the n900 will still heat a bit
