Overclocking i5 4690k causes overheating problems.
Hi,
I'm attempting to overclock an i5 4690k using an ASUS Z97-A motherboard. I'm using the Corsair H60 2018 AIO with the standard thermal paste. When running default settings or the XMP profile at 3.9ghz, the CPU stays around 35°C and reaches a maximum of 59°C under Prime95. That's acceptable given the room temperature here. If I try to push it to 4ghz or higher (targeting 4.4ghz), the idle temperature remains steady at 35°C, but Prime95 causes it to jump to 100°C and then throttle. This also occurs during gaming, where temperatures sometimes reach 100°C before dropping back to 60-70°C.
I'm following the same steps as in the video you linked:

I'm not very experienced with this process.
My setup includes a Fractal Design Meshify C motherboard, two 120 fans front-mounted and an AIO exhaust at the back. I also have an ASUS GTX 1060 STRIX and 16GB of 1866 DDR3 RAM from Crucial.
Your voltages could be excessive, especially at 4Ghz+. The voltage you're applying seems to be too high, and any minor rise in voltage combined with significant temperature spikes indicates you exceeded the safe limits.

Your voltages could be too high, what voltage are you using at 4Ghz+? A slight rise in voltage and a massive temperature spike suggest you pushed it beyond safe limits. I began at 1.175v, which also caused these issues. (I posted the original question from an incorrect account; this is my post) I also think my two 120mm intake fans aren't delivering enough airflow (using the standard fractal design fans that came with the case), so I'm upgrading to Corsair ML140 fans today. I plan to reinstall the CPU and cooler, and replace the default thermal paste with Noctua Thermal Paste.
Currently, the side of the case should be removed to allow proper airflow, and you're checking if the AIO is effectively drawing in cool air.
