Use the i9 13900K in combination with the Corsair iCUE H170i Elite LCD 420mm with 6 Noctua NF-A14 140MM 3000RPM fans in a push-pull configuration. They can still keep the processor at 99C max with FPU stress for 10 minutes using Aida64, which is somewhat comparable to Prime95 in terms of load and temperature.

This is with a room temperature of around 21C where the video card isn’t as warm (GTX1080Ti to 320W).
At peak times, the processor consumed about 310 watts with a bottom voltage of -0.04V (Global Core SVID voltage), since it does not reach 100C, then the clock speed remains at 5.5GHz / 4.3GHz.

Now it works quite stable at a low temp of -0.06 a friend even set it to -0.07v with no problems then the consumption drops to ~280-290W I think max temps are around 95C while at MUCH MORE Realistically normal scenarios I don’t see it getting above 80C starting in games like GTA V, World of Warcraft and Halo Infinite, of course the wattage is around 90-110W and 100-170W.

This is with the fans at 3000rpm (well they get 2750rpm) and 2450rpm for the pump (balanced profile), now the fan profile has been tweaked to around 1750-2250rpm because it doesn’t make much difference on Anyway at higher speeds but quieter.

I think I was able to achieve peaks of 360-370W via the Prime95 but there was no dip at the time but it soon got to 100C and started to choke. The bottom provides lower power consumption, less heat, gives the cooler more surface area to prevent throttling and you have more net performance.

Even with -0.06v undervolt I was able to get top scores in Cinebench R23, higher than without undervolt. (single run 40839 to 40856 dots from 300-318W to 290W approx.)

Now you will say, why such a processor? Been on an i7 3930K (dating back to 2011) since 2013 but with Windows 10 things got a little sluggish with day to day use, but it had to use a lot of its max capacity in some games and even Halo Infinite was constantly running on 100% with frame rates of 30-60 or even lower, and that’s now more than doubled (~100-130+) despite the 1080Ti loading at 99% even on low settings (1440P/120 FOV).

The i7 3930K has a TDP of 130W and even at 4.4GHz for overclocking under Windows 10 it was still far from achieving the performance of Windows 7 with 3.8GHz, but it could achieve this consumption where almost full load was required. (up to 180W under FPU voltage test).

The i9 13900K is so efficient that in fact it is not inferior in terms of consumption compared to the old processor in fact it has so much power that you can do a lot with less power consumption because in idle mode it also drops to 25 watts your games will have similar limits For what you’re going to 3930K (whether 165Hz is maxed out with less CPU power), the final consumption will simply be less than the old system, so it’s not black and white and totally depends on the user’s circumstances.

And you often hear that it’s better to upgrade your video card for games. Without a good foundation as a processor, you can still put a powerful video card in it, but sooner you will face a problem that the video card can’t be. Fully utilized and frame speed is poor due to extreme lag spikes due to limited CPU capacity.

Upgrading from i7 3930K to 13900K, though 1080Ti, a world of difference in maximum frame rates achievable and framerates being more consistent/smooth, and where programs used to take time to load, everything is now almost instantaneous, with the 840 A normal Pro SSD, a VM is also started and only booted three times in terms of boot times, etc.

Where the old system was drawing about 600-650 watts at peak moments, it’s more likely 650-700 watts if you’re going to put a heavy load on both components, but while gaming it’s more likely 400-550 watts on the new system, while the old certainly Keep drawing 550W in heavy gaming. Good thing it will be more in the future with the heavier GPU, just games that now draw full power no longer need that in the new game, they can also end up lower.

And I believe that instead of 7 fans (including the CPU), there are now a total of 14 in the system.
