Could you clarify if you're asking about expected temperatures during an IBT event?
Could you clarify if you're asking about expected temperatures during an IBT event?
Dear gurus,
I'm experimenting with some OC attempts on my (old) 4670K (3.4GHz). I used Gigabyte's EasyTune (which comes with the motherboard) and chose one of the default settings—medium—which pushes my CPU up to 4.2GHz.
After running IBT for 10 rounds, the results look excellent. However, I'm not very experienced with OC and am unsure about CPU temperatures during the tests.
My CPU is cooled with a Corsair H110i liquid cooling system. The temperatures of the four cores ranged from about 30 to 95-100°C (two hit 100, one at 99 and one at 95). The package temperature also reached 100°C. Is this typical or should I expect more spikes?
Also, my H110i never exceeded 35°C—would those spikes be unusual here, or would a longer test be necessary? (IBT lasted around 90 seconds). Would it be better to extend the testing time?
Thank you in advance for your help!
90-100C is extremely high. The CPU has hit its thermal limit and has slowed down. You might want to boost the fan speeds or reapply thermal paste to the CPU. With this cooler, it shouldn't get that hot.

temperature is quite high at 90-100C. the cpu hit its thermal limit and slowed down then. i think increasing the fan speed or reapplying thermal paste would help. using this cooler should keep things cooler, though the cpu still reaches around 95. i’ll lower the fan speed again once i get new thermal paste. Thanks!
I wouldn't rely on any presets without checking what they do. The typical error from those motherboards is using an excessively high core voltage. This guarantees the preset functions but causes extreme heat. A normal core voltage for a Haswell CPU should be around 1.3 volts, while 1.35 volts often results in the overheating you mentioned. If you're targeting 4.2Ghz, I recommend the link provided.
