What would be regarded as excessively warm?
I have an i7-7700k and a Cryorig h7 cooler. I recently experimented with overclocking, achieving 4.9Ghz at 1.45V but maintaining low to mid-90s temperatures under stress. Alternatively, I can reach 4.8Ghz without voltage changes while keeping temperatures in the mid to high 80s. Should I continue with the 4.8Ghz overclock or is the CPU suitable for lower to mid-90s temps?

Although the Throttle temperature is set at 100°C (212°F) for the i7-7700K, it’s not safe to push your CPU close to its thermal limit. If the hottest Core approaches its stated Tj Max Throttle temperature, then the CPU is already too warm.
Experts agree that keeping temperatures lower enhances stability, performance, and lifespan. It’s wise to maintain a comfortable thermal buffer below the Throttle threshold, no matter the surroundings or system setup.
Temperatures exceeding 85°C are discouraged.
What tools are you testing with? I'm not an expert, but 90* at high altitude looks fine. I wouldn't operate it at those temperatures or voltages. Keep it below 1.4 and in the lower 80s.
I'm trying to stay within my limits, you know. I don't want my CPU or GPU going over 80c. It's better to lower the frequency and voltages a bit unless you really need that full 4.9GHz clock speed. Or maybe just install a water-block and push it up to 5.0Ghz. If I were you, I'd undervolt and clock it at 4Ghz while keeping the temperature around 60 degrees. But honestly, I'm a patient gamer who's fine with 720p at 60 FPS with V-Sync.
7700k performs well up to 100°C with a TJ limit. I aim for under 90°C during stress tests, while keeping game temperatures between 50-75°C. That’s my general guideline. What is your Vcore setting?
Although the Throttle temperature is set at 100°C (212°F) for the i7-7700K, it’s not safe to push your CPU close to its thermal threshold. If the hottest Core approaches its stated Tj Max Throttle limit, then the processor is already excessively warm. The general opinion among knowledgeable builders, reviewers, and overclockers is that lower temperatures yield better stability, performance, and lifespan. All experts agree it’s wise to maintain a comfortable thermal buffer below the Throttle temperature, no matter the surroundings, system setup, or workload. Temperatures exceeding 85°C are discouraged. Temperatures under 80°C are considered optimal. Changes in ambient conditions cause core temps to rise or fall accordingly. The typical normal room temperature is around 22°C or 72°F; for every degree above that, so are your cores.
What’s your room temperature?
Overclocking is constrained by both voltage and heat. Too much Vcore and core temperature can trigger early electromigration damage—see the linked resource for details. This damage weakens the processor’s internal traces and junctions, leading to more frequent blue-screen errors over time. The recommended maximum core voltage varies with microarchitecture from 14 to 65 nanometers since 2006: with advanced cooling you may surpass the 85°C mark, while lower-end cooling will hit it at 85°C. In any case, stop once you reach your chosen limit.
Keep in mind the balance—small speed increases, like moving from 4.5 GHz to 4.6 GHz, are barely perceptible and don’t significantly affect overall performance. Pushing beyond suggested core voltage and temperature isn’t justified just for marginal gains.
