Water cooled 8700k temp issues
Running a 8700k with a master ml240l water cooler on an asus prime z370-a is working, but I'm struggling to maintain a stable 5GHz OC without overheating. To keep it running for over 10 minutes under a synthetic load, the temperature should stay around 1.4v, where the temps are in the high 90s. Everything looks fine with the cooler, but I've noticed reports of higher frequencies being common. Thanks in advance.
I wouldn't suggest running continuously at 1.3v or higher. Definitely avoid 1.4v. As Ryan mentioned, the temperature problem was resolved by reducing the CPU load. Regarding the overclock, not all 8700K models can reach 5GHz. Most achieve 4.8-5.1GHz with appropriate voltage settings. The typical method to detect an overclock limit is when a substantial increase in voltage is needed for the next 100MHz.
P.S.
This CPU might still be able to hit 5.0GHz, but it could depend on finding the right configuration. Factors like VCCIN, VCCSA, VCCIO settings, fixed or dynamic mode, VRM switching frequency, and load line calibration all play a role. Other aspects such as cache multiplier and RAM speed also matter.
Many attempts at 1.3v are using CPUs without delidding if 1.4v is getting you into the high 90s, which is problematic. You should either reduce the overclocking or think about removing the CPU. Another choice is to upgrade your water cooling system, such as a custom loop, but delidding remains a more affordable solution.
I wouldn't suggest running continuously at 1.3v or higher, especially not at 1.4v. As Ryan mentioned, the temperature problem was resolved by reducing the CPU load. Regarding overclocking, not all 8700K models can reach 5GHz; most achieve 4.8-5.1GHz with appropriate voltage settings. A typical sign of an overclock limit is a large jump in voltage needed for the next 100MHz.
P.S.
This CPU doesn't necessarily stop at 5.0GHz. It might just need the right settings—such as proper VCCIN, VCCSA, VCCIO values, correct fixed or dynamic mode, accurate VRM switching frequency, and load line calibration. Other factors like cache multiplier and RAM speed (lowering RAM speed can add headroom) also play a role.
P.P.S.
Don't expect miracles from your AI-O. The term "liquid" in the name doesn't guarantee excellent performance. Many high-quality air coolers can provide similar or better cooling with less noise.

Affirmative!
Great observation!
