1.upper portion
2.custom rom (paranoid android v 4.6 beta 2)
3. 4.4 based
4.not really but kinda, usually lasts around 10 hours of average use
5.started out stock rom, flashed latest phoenix, cyanogenmod, dn3, and paranoid android
Clearly CPU overheating is the issue. I too had overheating issue. I too did flash several ROMs. But, it all started with DN3 ROM. After that no matter what I flashed my CPU would heat up quickly.
Issue is closely related to kernel. It happens due to migration from one ROM to another. In most cases the wipes and installs are clear. But sometimes things go wrong unexpectedly.
You can try some solutions:
1. Stop indexing service with Titanium and check.
If warm again,
2. Power down the phone, remove SD card and wait for device to cool down. Restart and check.
Still not then
3. U will have to flash stock recovery on your device and do a wipe/ factory reset from the menu. (Of course u will lose all the data on internal SD card). Check for at least 2 battery recycles.
If not then,
4. Backup everthing EFS, CONTACTS,etc and flash stock rom via pc odin. When phone reboots and reaches language screen. Power it down, go to recovery and do a wipe/ factory reset.
This should surely solve your overheating problem.
If not, it might be a hardware issue.
