Seems like the thermal results very from one review to another so I think we will need to read more reviews to compare. Different review sites used different CPUs and software to stress the coolers.

Mainstream Intel CPUs from Ivy Bridge till the newest Coffee Lake themselves have inefficient stock thermal paste and excessive gap underneath the IHS so these factors also need to be taken into the account. The thermal results won't be as accurate as the ones tested on the enthusiast-class CPUs (ie. 3930K etc) with soldered thermal interface. Furthermore, bigger chips like the 3930K have larger contact surface than the smaller CPUs.

G3D: performs similarly compared to Kraken X62 (based on 4790K)

Vortez: beats Kraken X62 by 13C (based on 3930K)

OC3D: outperforms Kraken X62 by 14.5C (7700K @ 5.0GHz)

After all these years, you are still an enthusiastic overclocker who always do a lot of tests and reviews. Really thank you for surviving the "cpu overclocking" thread. And your 8700k bench scores are great, low Vcore @5.0 GHZ!

Thanks for your kind words... ehh without support from you guys this thread will be dead.
Regarding the low vcore 5GHz OC, I think I am just lucky to have found a nice chip.
No need to resell and buy another chip just to bin for better one like the old days.

Did you still buy a lot of chip for lottery back in 4th, 6th gen? Back in our ivy bridge, a lot of people did that! Could it be due to good cooling and you able to lower the vcore to run at around 6x C during bench?

Hi guys, i am new to OC. i am using 8600k with gigabyte aorus 5 and deepcool ex 240 aio. I manage to get 4.5ghz around temperature 78 degree celcius when full load with prime95 without tweaking anything in the bios other than multiplier itself. Any suggestion from here for daily usage? Thanks

Hi bro, welcome to OC club. 
With the auto BIOS settings, you let your motherboard to decide your voltages etc.
Depending on your board, auto CPU voltage (vCore) might be way set way too high than your CPU actually required.
For 4.5GHz, try manually setting the vCore at 1.1-1.2v (chip dependent).
For 5.0GHz OC guide, read this (shared in post #1 of this thread).

hi, i trying to change the setting in my bios but it seemed that it dont let me to change anything about cpu clock ratio those. Any solution to this problem?

anyone interested in buying a highend rig?
wanting to sell around 30k++

High end rig for sale! 
It would be better if you could list down the parts included as well as some pictures showing the setup etc.
I also noticed you have a WTS thread separately, perhaps you can put up more details there.

Want to ask . If im planning to build an OC rig with a i5 8600k aiming 5ghz. I have shortlisted 2 mobo in mind. Gigabyte Z370 Aorus Gaming 5 and Asus Strix Z370-F .
I am aware Asus mobo had some vdroop issues in the past and seems like solved with a bios update.
Assuming both mobo is same price, which one to pick?

Anyone here using single 240 radiator oc 8700k can i know what the temp tq  want to change to itx
