Throttling issue detected at 70°C for i5 8600k processor
I have an i5 8600k on a MSI Z370 A-PRO board with an EGVA AIO water cooler. My clock speed is set at 5000MHZ, but Cinebench R20 initially runs at 5000 for about 20 seconds before throttling to around 4500 MHZ. I'm using CPUID Hardware Monitor to track speeds and temps. Voltage was adjusted to 1.280, but all other settings remain auto. I'm concerned about power delivery limits and want to know if this chip can handle temperatures above 80°C.
If temperatures exceed 80°C, coolant performance may deteriorate under a prolonged heavy load, especially with varying radiator sizes...(thermal runaway occurs; as coolant heats up it retains less heat, causing further warming, etc...) You might safely apply a uniform multiplier based on your cooling system's ability... Above 80°C, maintaining 5 GHz would be risky. Monitor Prime95 results at 26.6/s small FFTs (default Blended mode), which remains the benchmark for CPU thermal testing. A crash is likely within two to three minutes if core voltage can't sustain the required all-core turbo speed, as seen in my 7700K tests aiming for 4.8 GHz at default voltage...
