Considering a lower voltage?
Considering a lower voltage?
After spending many hours browsing for information about my temperatures, I came across a Reddit post from someone who used their X72 Kraken as a top mount and reported high temps. When they removed the top panel, their temperatures decreased. I plan to check mine now. I attempted to set the vcore to 1.3 but it was unstable, so I’ll try to understand the adaptive voltage issue and see if that works. I’m not very experienced with downvolting, but overclocking seems simpler since there are plenty of guides and even Gigabyte provides instructions for reaching 5 GHz with an i9-9900k.
It's quite challenging to locate reliable data on actual manual voltage configurations for a standard default configuration and stock values. I faced similar difficulties when trying to reduce the auto voltage vcore and IO + SA auto voltages for my 9900K. While there are many discussions about achieving a 5GHz all-core overclock, finding information on reducing it was more difficult. The same applies to the 9900KS, as most threads focus on reaching 5.2GHz or higher.
I adjusted the same settings I used during overclocking, but changed the offset values and aimed for closer alignment with Intel specifications. These adjustments help balance Vcore, stability, and heat. You can also apply them in reverse.
Keep in mind to modify one setting at a time. Changing both vcore, vccio, and vccsa simultaneously can lead to instability.
If you choose to underclock by reducing the multipliers, consider using a “per core” multiplier approach. This allows you to set individual multipliers for each core—such as 50 for 5GHz cores and 49 for lower frequencies. This method lets your CPU run at 4.9GHz when all cores are active, while still boosting to 5GHz with fewer cores. I tried this during my 9900K overclocking and it significantly improved max load temperatures compared to full-core 5GHz.
However, since this was an overclock experiment rather than a standard configuration, the results may differ from your KS setup.
Always benchmark after making changes, and consider using a negative AVX offset if needed. I still think your CPU should work well with the default settings when paired with your cooler.
The 9900KS shouldn't be overheating excessively...
Make sure the Kraken's pump is functioning properly. Inspect it carefully while the device operates:
-cpu block
-tubing
-radiator
They shouldn't be unusually cold, except possibly the 'return to cpu block' tube.
Thanks for the update, dude. The top of my tower feels a bit cooler now. I plan to try a front mount to check if it improves temperatures and will test it with my H100i V2 aio. I also spoke to someone on Reddit who’s running 5 ghz at 1.24 volts stable.
No, because the critical temperature is 100C on that CPU. It would have caused a shutdown if you had kept testing.
It seems the radiator is functioning properly.
It looks like the problem might be with the motherboard – specifically the auto settings, which are likely set too high.
That particular motherboard doesn't meet Intel's TDP requirements and is providing excessively high voltage.
Your CPU is essentially a representative sample of the 9900K; it should handle 5.0GHz at lower voltages than that.
If that's accurate, then your motherboard's auto settings are probably set far too high...
I received a reply from Intel after submitting performance tests and data. They confirmed everything is okay but mentioned I only have three RAM modules installed, even though I have four. I plan to rearrange the RAM, ensuring all are detected. If that doesn’t work, I’ll test each one individually to identify the faulty unit. If all fail, I’ll need to return the board via RMA. In the meantime, I’ll reach out to Gigabyte support to inquire about voltage issues and what I’m experiencing—my luck is always this way.
