Recently, I built my first computer and tried to overclock using this tutorial :https://rog.asus.com/articles/guides/the-kaby-lake-overclocking-guide/ I don't really understand it, but I can adjust the vcore and the multiplier to get 4.7 gHz with vcore =1.24 V. My computer can pass a 4 hours realbench while all the cores reach ~80 C (max temp =85 C). For me, this temperature is very high, and if I overclock ram with xmp profile, the temperature can even reach 88-90 C. How can I reduce the temperature? I don't know whether my cooling system has problem, or temperature drop can be only archived with better cooling system.
The 7700K is known to run hot when overclocking. Intel played a cruel joke by using toothpaste between the die and the IHS. If you want to get a decent OC you are going to have to do the delid process. You can either do it yourself or send it off to Silicon lottery and they will do it for a fee and test it to see what OC your chip is capable of.
I delidded mine and replaced the crappy TIM with cool labs liquid ultra and the temps dropped 20C. This is not to be taken lightly as this is metal TIM and easy to botch and it will 100% void your warranty.

I applied my thermal paste (kryonaut thermal grizzly) but the temperature was still high. I think my room temperature is ~20 C. If I delid my CPU, do I need to replace the liquid metal over time?
The liquid metal TIM hasn’t been on the market all that long but so far there is no indication it breaks down and needs to be replaced.
20C is more than fine for an ambient.
You can apply all the TIM you want 20 ways from Sunday and it won’t change anything. Pulling heat off the IHS is pointless if the IHS isn’t pulling the heat off the die. **
