My 4790K operates at an average of 70 degrees C with occasional spikes up to 80.
I'm using it at 4.5Ghz, a Vcore of 1.198V, and it's running smoothly.
The default Vcore was 1.260, so I lowered it to 1.198V in an attempt to lower the CPU's maximum temperature, but it doesn't seem to make much difference.
The temperatures still rise to 80 occasionally, which is almost undetectable since my average is around 70 degrees.
Could these readings be an issue for the 4790K?

Temperatures by themselves cause less harm than high voltage would. Increased voltages raise the likelihood of electromigration, which can damage the silicon in your CPU die. Your current voltages are fine, so this shouldn’t significantly affect longevity compared to standard settings.

Also, when a CPU gets close to extremely high temperatures, it will start throttling to protect itself, lowering performance as it tries to cool down. If it becomes very hot, the system usually shuts down automatically. I’ve heard that Haswell chips tend to reach around the 90s before thermal throttling occurs.

Generally, if the CPU doesn’t throttle, everything is okay. But many...

I think that your cpu's temps are fine, especially given that overclock you have for it.
Lowering voltages will only really help temps if you have too much of an excess for a given cpu frequency. Even with lower voltages, you are still pushing your cpu to work harder (overclocked) and it will try to draw the appropriate power it needs to particular parts of the cpu, which is why your cpu gets hot even at lower voltages.

Thanks for taking the time to reply.
Just wondering coz I read elsewhere on this forum that 80 degrees is bad for the CPU longevity..
What do you think about that?
Should I step down the frequency?

Temperatures by themselves cause less harm compared to high voltage. Increased voltages raise the likelihood of electromigration, which can damage the silicon in your CPU die. Your current voltages are fine, so this shouldn’t significantly affect longevity beyond what we’d expect from standard settings.

Once the CPU reaches very high temperatures, it will start throttling to protect itself, lowering performance as it tries to cool down. If it gets extremely hot, the system usually shuts down automatically. I’ve heard that Haswell chips tend to thermal throttle around the 90s.

In most cases, if the CPU doesn’t throttle, everything is okay. But many overclockers prefer keeping temperatures below 70 degrees, as it feels more comfortable. If you’re okay with temps reaching up to 80, that should be acceptable. If not, you might want to improve your cooling solution or reduce your overclock slightly.
