Intel Core i9-14900KS alleged benchmarks leaked — up to 6.20 GHz and 410W power draw | Tom's Hardware (tomshardware.com)

410W is obscene!

I just moved from intel to a 7950x3d 

And what can I say !!! 🤩 wow.

great performance .

paired with. 3080ti and 6000mhz ram.

will Def be getting the 8960x3d ig my mobo supports it. Fingers crossed.

 paired with. 4090

 

Mikey, what are you cooling that thing with?  What kind of temps in MSFS?

So is 500w 4090 but under normal gaming it`s below 300w. And it`s likely the same will be true of the 14900KS under normal gaming use.

So true!  I have a 4090 and rarely go above 300w.

I really like my 7800X3D + 4090 setup with MSFS, temps are around 55C to 60C in a typical sim-session.  I cool it with a Corsair H150i (360mm) although that's overkill...

I run 32GB of G.Skill Trident Z5 (2x16 sticks) model# F5-6000J3040F16GX2-TZ5K which is/was on the QVL list for my ASUS Rog Strix X670-E Gaming Wifi 6E motherboard.

A  Corsair H150i 

cpu at 70c

CPU cooler is only good if the case temps are handled correctly. I have custom case fans 4x140mm that move air through the case as fast as possible. heat buildup in the case will defeat the best CPU and GPU coolers this will cause throttling after a time.

4090 will be way lower than 300W because I will only be running it at around 30FPSx2.  4090 is only for FG and VRAM.

Have never seen throttling in 30y of this because yes good airflow.  I use a Phanteks FT case which sports a large floor fan which draws in air directly from the basement thru a port in the floor below the case so it's always being fed with 60F air will helps a lot.  My 9900K rarely sees more than 58C under load, on an air cooler.

I undervolt both my CPU and GPU, that keeps them cool without any performance loss.

My 7950x3d runs mid 40s which is great because my fans aren’t screaming. Running the Corsair H150i as well.

What do you have the 7800X3D voltage at now?  Any other changes need to happen besides lowering cpu voltage?  I have a Noctua NH-U12A and under MSFS load average CPU core is around 64C with a brief peak of 70C once.  Obviously these are totally fine but if it can be lowered w/o loss of perf all good.

After getting memory setup correctly I haven't done anything beyond BIOS defaults for CPU performance.  I disabled HT or SMT whatever it's called.  Anything else you can recommend to improve performance w/o introducing instability?  I had all cores on my 9900K at 5gHz for the first 3y, then reduced it to 4.9gHz and increased voltage a bit as I was getting some instability and lockup crashes.

For my brand new build I have 5x140mm and 1x200mm case fans, and the Phanteks case came with a PWM hub on the back of the case.  I connected the hub per instructions including setting each fan to PWM mode and Smart Mode, but the BIOS does not display each fan's RPM, while it does let me set them with the usual graph line w/ moveable dots to cross spin rate and temp it just doesn't display what they're doing.  The same applies to the MSI Center app which supports the motherboard.  That app lets me set Custom settings per fan in Smart Mode, as well as one-click options for Extreme, Balanced, Silent and Custom, and they clearly work indicating the hub was setup correctly I'm pretty sure.

Can one see actual spin rates if you plug each fan into its own header?  These are all 4-pin.  This motherboard I think has 6 fan headers including the CPU header.
