Overclocking the Intel 8600K - Delidded on Air and Water

We've gotten to spend some quality time with our Intel Core i5-8600K Coffee Lake CPU, and of course we have spent our time finding out just how far we could push the processor's clock under both Air Cooling and Water Cooling. We relid and delid as well. The results look to be very promising for the overclocking enthusiast and gamer.


Stock TIM Replacement

When we say "stock TIM," we are referring to testing the 8600K with the thermal interface material that Intel places between the IHS (Integrated Heat Spreader) and the CPU die. This has been a fairly large point of contention between computer hardware enthusiasts and Intel for a while now. The reason being is that the stock TIM used by Intel is anemic at best, and simply a cost saving process at worst. AMD on the other hand uses an indium based solder as its TIM. A solder TIM simply conducts heat much more efficiently than the tragic paste Intel shovels into its "enthusiast" SKU processors. So, since Intel has left us with a feeble TIM we have to do our best to fix that. The video below outlines a very safe way to go about delidding your expensive CPU that came with a cheap TIM. (Can you feel the love, Intel? Me either.) The tool we use is version 1 of the Delid Die Mate. Some small modifications are needed to make it work on the Coffee Lake as noted in the video below. Version 2 is for sale now and officially supports a few more CPUs than the original. I do not know if version 2 supports Coffee Lake delidding, but since it supports Kaby Lake, I would suggest it works just fine. As you see in the video, our processor's physical dimensions between Kaby Lake and Coffee Lake CPUs are nearly identical.

Once you get the CPU cracked open, we want to clean the 8600K thoroughly with a plastic razor and 99.9% alcohol, and then get the new TIM in place. We are using Coollab's Liquid Ultra. From there a bit of Red RTV is used to re-seal the IHS and from there we give the RTV a full day to cure. This will give us the best Z height in our experiences. The video below outlines the process of relidding our 8600K.

No Specialty Tools?

You can certainly relid with no specialty tools. We wrote an article on relidding with no specialty tools. Delidding however is going to take some sorts of tools. We wrote an article showing how to use a 3D printed tool with a vice or a hammer , which made for some fun moments. Some folks elect to delid using only a razor blade. Go with whatever works for you should you wish, but as with lots of things where overclocking is concerned, you are very likely going to void your warranty. Take your time and make sure not to damage your hardware.
