i5 4690k Overclocking overheating issues

Hi,

I am trying to OC an i5 4690k on an ASUS Z97-A motherboard. I have a Corsair H60 2018 AIO (using the stock thermal paste that came with the cooler).

If I run the default settings (no OC) OR the XMP profile (3.9ghz), the CPU idles at 35C and under Prime95 it tops out at 59C. Pretty good, considering its 28C ambient temperature here.

If I try to OC the CPU to 4ghz or above (target OC is 4.4ghz), the CPU idles at the same temp (35C), but under Prime95 it immediately skyrockets to 100C and throttles. This also happens during gaming, I see that temps sometimes hit 100 and then come back down to 60-70C.

I am basically doing everything the same as in this video when OCing: https://www.youtube.com/watch?v=2ERLk7Qus-A&t=215s

I am not that experienced at this.

My case is the Fractal Design Meshify C, I have 2 120 fans pulling at the front and the AIO is the exhaust at the back. I also have an ASUS GTX 1060 STRIX and 16GB of 1866 DDR3 RAM from Crucial.

Thanks

Your Voltages might be too high, what voltage are you setting when hitting 4Ghz+? When there's a small increase in voltage and a huge increase of temperatures it means you pushed it too far

I started at 1.175v, which lead to those same results. (posted the original topic from wrong account, I am the OP)

I also feel that my two 120mm intake fans are not providing enough are flow (using the default fractal design fans that came with the case), so I am upgrading to Corsair ML140 fans today. I am also going to try reinstalling the CPU and Cooler, will also substitute the default thermal paste (it came pre-applied to the heatsink) with Noctua Thermal Paste.
