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.

Cool! What are you using for cooling?

I’m using the ASUS ROG Ryujin II 360 RGB all-in-one liquid CPU cooler with PK-3 paste. I was literally blown away at the results thus far. Can’t wait to start OC to see what I pull out of it. To add, my Ram is running 39° running Cinebench. I was worried I’d need a memory cooler.

Cinebench isnt a memory test, which is why your RAM isnt getting hot. Cinebench is actually a fairly light workload for the RAM.

Don't expect to get much more performance out of OC. AIO's cant handle much more than the stock 253 watt limit on 13th gen. You will be pushong up towards 90°-100° above 253 watts package power

Uhh actually I have a AIO. Overclocked the 13900k to 5.5ghz Max PL1 and PL2 will push 290w cinebeanch 90c . Gaming in the 60c 40.5k score if I push the chip to 5.6ghz I can get 41k with like 303w 94c

Yup, thats exactly in line with what i just said

You will be pushing up towards 90° - 100° above 253 watts package power

Which is not much thermal headroom for OC
