Does an average Temperature of 70 degrees affect cpu lifetime?

[Bronski]

When running windows only the  i7 13700 cores have a temperature between 30 and 40 degrees Celsius. When gaming at least two cores have a temperature between 70 and 80 degrees. The other cores are between 50 -70 degrees.

So 70 degrees is the permanent/steady temperature/temperature-load (sorry I don't know the right term).

Does this affect the cpu's lifetime ?

I have only two fans + cpu-fan in my case. Can I reduce the temperature further by installing more fans ?

Is  water-cooling absolute necessary ?

These temperatures are perfectly fine. Your processor is happy at 70c. In fact, Intel will tell you that anything below 100c is fine, but I would say that you should target keeping sustained temperatures below, say, 90c (but short spikes above that is ok).

Sounds like you don't need to do anything further - and no, water-cooling is NOT absolutely necessary.

Thank you for your answer.
