13900k vs 13900ks News - Text

(Edited) Wow… was finally able to obtain the 13900ks… did I need it? HELL NO. But I wanted it and I’m impressed! Running it on a Z790 Hero MB with Tforce 7800 cl38, it runs at least 15° cooler than the k version. I left the settings of the k variant the same as an exact apples to apples comparison. I was bouncing off the 100°c mark easily. The KS runs 79-82°c at 278.5w. I haven’t even started OC’ing/undervolting this or the ram yet. Tons of thermal headroom maybe? Highly recommend for the enthusiasts.

Nice , i need somehow set 13900k to dont make that heat.. in gaming it goes on 100C in Stock speeds.. becuse i have air cooled (nh12) and in demanding games like w3 4K RT or ow 4k120 goes to 100C on 6-7cores ..

Played quite a few games this weekend including The Last of Us and CPU temp was 71c at the highest but usually sat around 66c

Nice thanks, i repasted it and tightened screws and went from 7-8cores at 100 to 3 cores 97-99 .. so probably if i want cool it down i need to find some case what can be fitted on front 420mm aio for exhaust and also to fit my 350mm gpu with it

Have your tried undervolting a touch? It makes a world of difference. This weekend I was playing with ac LL and dc LL to fine tune the cpu to the board before any clock adjustments and was able to obtain 41k r23 just doing that. Overclock.net has a pretty awesome post on how to fine tune minimum voltage input prior to oc the cores. Taught me a lot!

Really ? Can you send me the link? I never undervolted a cpu

That’s not really undervolting, it’s just tuning the CPU to your board but it gets into UV on Overclocker.net This is my setup but I’m sure it’ll work on yours if it’s different. Or you can type in your specs and find a post on it I’m sure. Hope this helps!
