Voltage, heat, frequency of CPUs?

[true1hart]

Goal is 4470MHz all cores 3950x.  Was 4.4GHz all core for a long time and didn't crash under any benchmarks, games, or video editing.

 

I want to know what degrades (kills) the CPU?  Temperature, voltage, or heat?

 

When I ran 4.4GHz all cores, my idle temp was 35c, 55 to 70c gaming, and 86c using Prime95 or Cinebench.

 

If I can achieve the same results with the 4470MHz overclock, is my CPU safe?

 

My motherboard is a X570 MSI Meg ACE and I have a 1600 watt power supply (Corsair AX1600i). I also have a EVGA FTW 3 Ultra RTX 3090 overclocked (temperatures never go past 70c while gaming).

 

Thanks for your help!

Heat kills a CPU. Increasing the voltage increases the heat. Even if electrically the voltage itself has an impact keeping the heat in check will allow the CPU to live it's useful lifespan.

 

I still have a 3930K that I O.C.'d to hell and back. Still chugging along. Just made sure temps we're good.

 

CPU's are quite robust. You don't have to be overly cautious with them but if you're worried about overclocking decreasing the lifespan of the chip you shouldn't be overclocking at all.

Ok, thanks!
