What happens when a CPU becomes too hot? and how to cool down CPU

 

The CPU I'm using is I5 8400

You will thermal throttle if it gets too hot. If you get to 100 C, your computer will shut down as a safe guard.

 

What cooler are you using?

[linustouchtips]

The pc will shut down to avoid damage. 

 

What kind of a cooling solution are you using stock, aftermarket, liquid. 

 

If your running stock might have to suggest getting a aftermarket cooler like a Cryorig or Noctua for better thermals.

 

You can also adjust the fan speed for your CPU in the bios to cool it quicker at certain temps.

In the event that all failsafes fail, if the CPU gets hot enough, it'll enter a thermal runaway state. Semiconductors have a weird property where if they get too hot, their electrical resistance decreases, allowing more amperage, which increases the heat even more (https://en.wikipedia.org/wiki/Thermal_runaway#Semiconductors)

 

Basically at that point the CPU cooks itself to death.

[Mr. Question Asker]

Thanks all for helping.

 

Have a good one.

Wouldn't worry though, even the drastically STOCK Intel Cooler can manage an i5 8400 (in most environments bar a deserted desert)

But in due time, it'll still get quite warm, likely not enough to throttle clocks or shutdown.
