i5-8600k Overclocking Questions

[aDuck0nQuack]

I currently have a i5-8600k overclocked to 5ghz at 1.3V.  Quite often core temps on random cores will spike from about 35C to about 60C and then drop back to 35C. I have a Corsair H100i v2 and I'm wondering if its normal for the cores to randomly spike like they do and also if idle temps of 35C are normal.  I don't have pictures but under a full load on Cinebench temps are around 67C on all cores.

ur fine

Id only worry if it sustains 80C+, even then its not going to kill it any time soon, just potentially reduce its operational life span from "way past the point where it will need replacingg" to "the point where you will probably replace it anyway".

Pay attention under heavy load as even mine only peaks around 60C in normal usage but can easily reach 80C when encoding video so I had to drop it to 4.6Ghz.

Ok thanks. I think the reason mine stays under 70C under load is my cpu cooler

Yes it will be, although I have heard a good air cooler can achieve the same as is the direction I plan to go.

 

Although I'm seriously considering switching to the a new Intel 8 core CPU (assuming they aren't significantly more expensive) with them soldering the heat spreader, as that alone could make a huge difference.  I compared a 150W TDP air cooler to a 200W TDP air cooler (I had them both from old builds), and they make barely any difference as I don't think the heat is reaching the cooler efficiently enough to begin with.
