Chip running hot on blink sketch

Hello,
My ESP32 (TTGO) is running hot, and I think it causes eventual reset.
I first noticed it running complex code (sensors, WIFI, web server etc.) - it reached ~65 Celsius.
So just to test I run simple blink sketch:

function onInit() {
    let ledOn = false;
    setInterval(() => {
        console.log(`temp = ${(E.getTemperature() - 32) * 0.5556}`);
        digitalWrite(13, ledOn);
        ledOn = !ledOn;
    }, 1000);
}

Surprisingly even on above it reached 62 C.

I made same test with Mircopython:

import esp32
from machine import Pin
import time

led = Pin(13, Pin.OUT)

while True:
    led.value(not led.value())  
    print((esp32.raw_temperature() - 32) * 0.5556)
    time.sleep_ms(1000) 

gave me: 51 C

Arduino:

void setup() {
  Serial.begin(115200);
  pinMode(13, OUTPUT);
}

bool state = false;

void loop() {
  state = !state;
  digitalWrite(13, state);
  delay(1000);
  Serial.println((temprature_sens_read() - 32) * 0.5556);
}

gave: 53 C

Any ideas?
