Strange overheating on Android

[CometHunter92]

On my device, RP5, NooDS makes the cpu temperature to wildly oscillate, and reaching immediately 40°C/45°C from idle 25°C, seemingly randomly. I noticed on some games that the highest temperatures are achieved during the menus and not during gameplay, strangely. Other DS emulators, or even the Retroarch port of NooDS, don't act like that. Being seemingly more lightweight than other DS emulators seems like a strange behavior. I don't use enhanced resolution, and I've tried different settings for threaded rendering.
