Hey everyone, I'm building a setup to make things look good for 3D stuff like modeling and animation. I have an i5-8600K processor. Can the Dark Rock 4 handle a higher speed? Is it better than normal chips to keep my temperature down while I do these tasks?

OCs are never 100% stable. Even at their best, they only hit a 99.99% mark. When people gamble on that tiny 0.01%, you might lose a little bit, but it's not a big deal. The worst case is having too much data corruption and forcing a full restart of the Windows system and the game. It's just a game for fun. But paid work works differently. Even though time costs money, if you're 59 minutes into an hour-long render when things glitch, it doesn't mean much compared to running Prime95 all day in the heat. When you spend the next few hours fixing your PC, how much was that OC actually worth? You can experiment with toys and spend whatever you want on them, but don't mess with the ones that make your money. If you need faster render times, check out software that's more effective or look at platforms like GPU vs CPU rendering instead of trying to tweak a toy.

The Dark Rock 4 is a solid CPU cooler that lets you overclock, but only if your case has good airflow too. I've seen people push the Dark Rock all the way up to 4.8GHz, but that causes super high sustained temps. Instead, something like an all-core 4.6/4.7GHz should work well enough. Just test it with your specific games or apps to see if you can keep temps at 80 degrees C or lower and you'll be good. Vcore is also very important; keeping the voltage around 1.3V or below will really help cool things down too. One thing that makes a big difference is delidding, especially with Intel's 8th Gen chips. It can drop temps by 15 to 20 degrees C using Liquid Metal thermal paste. I used this on my 8700K and it was way easier than expected; lots of great guides on YouTube if you want to try it yourself.

If your system works really well and is stable, then why are you trying to speed it up by boosting its clock speed? That sounds unnecessary when everything runs fine.

Cut down rendering times? My idea is that if you buy a K CPU, overlocking and unlocking extra headroom go together. Why leave that extra power idle when it could be used? Some testing shows stable overclocks on Intel aren't hard to do, they can save minutes per render which saves time and lets you work more efficiently... But I'm just saying so!
