i7 6700k runs at approximately 4.7GHz with a voltage of 1.344v on an NZXT Kraken X61.
I've increased my 6700k to 4.7GHz at 1.344v and it handles a full load at around 75c with the Kraken X61 fans running at full speed. This temperature feels a bit elevated. With an NZXT S340, the X61 needs to be mounted front and the fans positioned at the front of the radiator as intake fans.
That's quite a nice overclock you have, with decent voltage too.
Them temperatures are just showing that you may not be able to go too much higher from that overclock, as the temperatures spike a little more when you're pushing your CPU a lot, and with the higher voltage and clock speed, 75c is perfectly fine.
I don't see anything wrong with what you have, and during gaming I doubt the temperatures will even be that high, how often it'd get to that temperature while gaming, it may stay around the 60s.
Not very high at all, actually it's excellent.
Intel's advice for the best lifespan of most recent CPUs is around 70 degrees Celsius, although voltage also plays a role.
If you intend to keep this for a long time, it might be beneficial to lower the voltage. You can adjust it later if problems arise, though this depends on whether any noticeable degradation occurs.
To put it simply, predicting how long such a CPU will last is nearly impossible.
Given that it reached 5.2GHz at 1.35V (and 5GHz at 1.3V according to some sources), you may consider slightly reducing the voltage if feasible. It's still a matter of silicon chance and the stability of the voltage supply (especially the motherboard VRM). Prioritize system reliability by running an overnight test with a suitable program. I usually use Prime95, though some people advise against it.
Photonboy shares his thoughts on the CPU's performance and longevity. He notes Intel's advice for optimal temperatures in the low 70°C range and mentions voltage effects. He suggests lowering frequency if you plan to use it long-term, though this depends on potential issues. Predicting CPU lifespan remains nearly impossible due to silicon variability. Since the processor runs at 5.2GHz with 1.35V and possibly higher, he recommends slightly reducing voltage for better stability. He advises testing with a suitable program overnight, like Prime95, but warns against rushing it.

The recommendation from Intel for the best performance of most modern CPUs is around 70 degrees Celsius, though voltage also plays a role. If you intend to maintain this setup over time, it might be beneficial to lower the frequency to reduce voltage. This adjustment can be made later if problems arise, although it depends on what exactly starts to fail.
It’s nearly impossible to forecast how long such a CPU will last. Given its current speed of 5.2GHz at 1.35V (and up to 5GHz at 1.3V), you may want to slightly reduce the voltage if feasible. This is just a matter of silicon chance—so be cautious about system stability.
An overnight test would help, especially since it’s convenient for me right now. I’m not an expert, but I found this site: http://www.playtool.com/pages/prime95/prime95.html. It might trigger false alarms, but I’ve seen errors before, even on my overclocked i7-3770K after years of use.
Major problems usually cause significant errors. Intel’s own diagnostic tool resets the CPU to default and won’t confirm your overclock; you’ll need to reboot or adjust settings manually. They also offer their own overclocking utilities, but I prefer doing it myself through BIOS/UEFI tweaks.
Photonboy shared his thoughts on the topic. Intel's advice for the ideal operating temperature of most modern CPUs is around low 70 degrees Celsius, though voltage also plays a role. If you intend to use this setup for an extended period, lowering the voltage might be beneficial. You could adjust it later if problems arise, depending on what causes degradation. It’s nearly impossible to accurately forecast how long such a CPU will last. Given its performance at 5.2GHz with 1.35V and up to 5GHz at 1.3V, you might consider slightly reducing the voltage. This is largely a matter of silicon chance and the stability of the power supply (especially the motherboard VRM). Prioritize system reliability—run an overnight test with a suitable program like Prime95, though some suggest it’s not ideal. Some recommend using P95 version 26.6 or earlier, as newer versions aren’t truly representative stress tests. He agrees that overclocking for performance is common, but reducing voltage and clock speed can extend lifespan beyond immediate needs, unless you push into higher voltages like 1.45/1.5V, which could shorten life significantly.
Photonboy shared some insights about the situation. Intel suggests keeping newer CPUs running at around 70 degrees Celsius, though voltage also plays a role. If you intend to maintain this setup over time, lowering the frequency might help reduce voltage needs. This adjustment could be done later if problems arise, but it depends on what specifically starts to fail. Predicting how long a CPU will last is nearly impossible, especially with components like this. Given that it recently reached 5.2GHz at 1.35V and possibly higher at 1.3V, you might consider slightly lowering the voltage if feasible. It's a silicon gamble—better to prioritize system stability by running a test program overnight. I recommend checking out Prime95 on a site like playtool.com for further guidance. There could be false positives, but I've seen them before even with stable systems. For now, it seems a blend might be worth trying. What voltage do you think would be safe?
