Default Overheating issue

I'm running Slimbean 4.3.1 ROM with Iodak 9.95 kernel. I have played Modern Combat 4 for like 10 minutes and the phone felt like it was about to catch fire. Any idea on how I could solve this?

Sent from my Optimus 4X
Device: LG Optimus 4X HD
ROM: Stock JB 4.1.2
Kernel: STOCK

underclocking and/or and undervolting is really all you can do, the are plenty of protections in the kernel for individual components from overheating, the phone will begin to throttle (automatically underclock) around 75c generally and shut down in the mid 80c. So other than the battery drain, theres not really anything to be concerned with.

How hot is the phone allowed to be? I wouldnt say that my 4XHD catches fire, but when I do something like play a game it is so hot that I cant touch the back of the phone for ~10 seconds because its too hot. Is this bad for the phone? I did no overclocking oder such things. Stock kernel and Vanir 4.3.

Well theoretically the SoC will start to deteriorate rapidly around mid 90c+ but it has built in protections, independent of kernel/ android to prevent that, still you would have to go out of your way to disable/ remove all protections in the kernel source before that become a problem.

The kernel will shutdown around mid 80s (this number is usually tweaked in custom kernels) but before that the cpu will start throttling mid 70s (and usually temps wont go past this)

Well not as far as the hardware is concerned, but it gets pretty uncomfortable to hold at 70c lol
