I am sure I did read a few times of people overclocking the K6 3+ that they said delid and copper cooler did help a lot.
But it also does look like the limit with cache 3 on is 115-120fsb
But look at this 😵 Level 3 enabled 😵

800 mhz is insane 😊
It depends on what they are doing with the chip. I could very likely overclock my 4790k to 5ghz (or near it) and get to the desktop stable enough to open CPU-Z and validate my clocks, but it would crash once I put any load on it regardless of my cooling setup because the chip simply can't take the frequency. Either it's not getting enough voltage for what you want, or it's getting too much voltage and static is dancing between the transistors to the point of trouble. To me and most people into overclocking, it's useless until you can get through a few (or many) stable passes of x264 or more extreme stress tests that are going to put a heavy load on the processor, and that's where aftermarket cooling, delidding, lapping, etc come into mind. It would keep the k6 cooler, extend it's life, that's true, and it will help you keep your overclock stable under heavy loads so you could take that big overclock in cpu-z and actually USE the computer without it frying. So you see getting a stable overclock consists of getting the CPU stable AND keeping it cool, only one of the two variables checked off and the system will crash (or burn).
So when people are saying the CPU isn't thermally limited, they are saying that you're basically at the highest voltage and frequency the chip can take and run stable, and it's within the specified operating temperature which I believe is 70C on these. I'm pretty sure k6 chips don't have an on board diode, maybe just a motherboard socket sensor to give you the old CPU OVERHEATING! warnings, so you still can't be 100% sure. Trial and error and a thermal probe could help, a delta AFB series fan on your copper cooler will help even more 😈. In my experience a good heatsink + fan will drop temperatures far more than delidding, I've used the cool labs liquid pro and others and typically only see a change on the order of zero to a couple degrees Celsius.
I see pictures in the link you provided, looks like the CPU is being phase change or TEC/peltier cooled which would bring it below ambient (room) temperature, something impossible on an air cooler regardless of the efficiency of your heat transfer from the CPU to the heat sink.
As for overclocking in this case I haven't played with socket 7 in ages, I'm sure there are plenty of guides dealing with sweet spots to try out with your memory and bus configs to get more speed out of the CPU, I'd look for whichever combo got the best real world performance.
One last edit: In my experience, it's almost always (99.9998%) the VRM (voltage regulator module) that blows out before the CPU could ever cook. So how far you can get may be very dependent on your motherboard and not the CPU. It's been a while since I've toyed with these older boards with socketed VRMs, but I'd wager a guess that the voltage required to run a stock K-6 at 500MHZ is already in the upper range of voltage I would want to pass through these old systems 🤣. Oh, and then there's the exponential increase in amperage being pulled from your power supply which could cause that to blow up as well 😜. Lot's of things to consider here along with delidding 😊 😊 😊
Sup. I like computers. Are you a computer?
