Should I be worried with the temperature?

For the Raspberry Pi 4, 60℃ is normal. You may want to check this thread.

Raspberry Pi 4B temperature issues with DietPi 6.25

My Raspberry Pi 4B with DietPi 6.25 is running a bit warm, theres no way i can put it in a enclosure. I even have tried a small heatsink, but it seems to be less effective than i’d like. My idle temp stays on around 55-58°C even though i limited cpu frequency to 600Mhz. (on a Pi3B+ this would be around 39-40°C) Actually my first Pi4B fried due to heat, so this is the second one running warm. Anybody else seeing this?
