I'm using esp-1 inside a switch box and cpu getting extremely hot.
1. Is there any method to dissipate the heat?
2. Would putting it to light sleep help to cool down a bit?
3. What would happen if keep it running as it is in that temperature? (As of now it is running fine for 2+ days. Not sure for long run it will get fried.)
4. Is there anyway to measure the cpu temperature and turn it off for awhile?

The power is supplied via a LM1117 and VCC, RST, and CH_PD pins are connected to the 3.3 source.
Also I have connected a 10mf capacitor.
Is this wiring ok?
