Hey y'all I wanna know what you're idle temps are on your 13900K please.
The voltage, how many watt, and cooler would be good bonus info but the main thing is what is your stock idle temps at the desktop?
 
Here's 13900ks (which is essentially just a binned 13900k)
Cooling - Direct Die with EK's block, 1x 360x60mm rad, 1x 360x45mm rad, 1x 420x45mm rad, and a 3090 also in the loop.
Clocks - 5.7P, 4.6E, 4.5C
Idle temp - 34C (Package); 29-31C (Cores)
Wattage @ idle - 28.148W
Voltage - 1.3v @ idle

Note, note a cold boot. I've been using the PC for several hours and had a gaming session for a couple hours, but these are where things have settle just watching Youtube and doing some light tasks.
 
I‘m really keen to work out what this looks like with speedshift, cstates, hardware duty cycling and core parking enabled…
 
One thing to remember is that at idle conditions, thermocouple values are erroneous according to an Intel white paper. They claim you should only believe temps when close to thermal limit. If I find the paper I will post it. My reported idle T for a 12700K is 27 Celsius.

Nice, thanks for sharing. That is some very good rad space.
 
my 13900ks stock settings except -0.025 negative offset is at about 33*C at idle. why does this feel high to me? although during high loads it cools amazingly. I can keep it from thermal throttling in any stress test on full 32 thread 330W load at 5.6/4.3 I guess I was just expecting the idle to be lower?

I hear you man. My 12900k usually idled 24-26C (copper IHS and LM) at 5.3. BUT it wasn't any cooler than my [email protected] under load.

Maybe the 13900ks just has a higher operating voltage or power usage which causes the higher idle temps?
I have a lot of radiator and cool air flow and the new quantum velocity 2 block all perfectly installed and can't bring the idle temps below 30c no matter what I do. I'm used to the 6900K and 12700K idle being in the 20s sometimes even under 20C so I'm alarmed not being able to break into the 20s with the 13900KS.
I know most of you are thinking you shouldn't care, but I want to know why lol

All C states enabled? Core parking enabled? Speedshift enabled?

Around 34 C with 28C ambient temperature
 
Default v core voltages BTW. Which I want to decrease.
and watercooled cpu. Have to upgrade my radiator...
If you're on the 13900ks you can go -0.025v offset completely stable. I tested undervolting this chip a lot. You can undervolt -0.085v if you shut off 12 e cores which makes a huge difference.

Not all 13900k(s) chips will be the same, some may not work with that.

this has been true since sandy bridge.
 
C states and speed shift are yes, core parking I couldn't find in the BIOS lol z790 Aorus master
Core parking isn’t in the bios… google quickcpu, set core parking to 2%.. enable power plan ( and while you’re at it, hit the c-state demotion stuff using the menu at the bottom)
 
So I caved and got a 13900k. Stock idle is about 4.6W, idle temp is about 28-31C according to the sensors.

Cinebench temps are about 75-80C full load. (with minor AC/DC LL tweaking)

package idles at 40-45 cores are anywhere from 30-36 around 10-15w 1.2 static vcore
 
I have my 13900ks Direct die idle 32c but cinebench load can see as high as 90c. i may undervolt after seeing this

Seems similar to a standard 13900ks temps but with direct die cooling? You should have seen massive temperature decrease. Unless you are overclocked very heavily.

chip before direct die was 98-100c load - now hottest core is 90 but the other p cores mid 80s

FYI I used the following method to undervolt

1. Set LLC to 4
2. Set DCLL to 1.02
3. Set ACLL to 0.25
4. Test
5. Reduce ACLL by 0.01v at a time, and retest.
6. When you get it to the point of instability, increase ACLL by 0.02 (you want a buffer). - Then you're done

I got ACLL down to 0.15 before it failed tests so pushed back up to 0.17

After doing that, cinebench temps are low 70s

is it better to undervolt a tad or ASUS MultiCore Enhancement Enabled - Remove All Limits (90c) ??

This is territory I have never embarked on lol. It's seems like a secret trick to drop temps by 20 degrees. I may try it. Where did you learn about this particular LLC and dcll and acll tweaks?
 
So, why in the world is my EK Quantum Velocity 2 blocked 13900KS with 960mm of rad idle 5 degrees or more higher than my air cooled 12700kf with a Deepcool AK620 dual tower air cooler single fan mode?
The 13900ks even has the thermalright anti bend bracket for perfect mounting pressure lol.
The 13900ks wants to idle at 35c idle when the air cooled 12700k can dip into the high 29c range idle.
I get that it is a hotter chip with more cores but it has 3 radiators and tons of air flow and the max load temp on it is laughably low so it is mounted perfectly but why is the idle so high? It's the highest idle chip I've ever had...
 
You need 1120mm of rads and an Optimus block to get a 13900KS down to 30c. Make sure your 4090 is on the same loop to further optimize heat transfer away from the cpu. And tell the e-cores to chill out. They think they gave to be working all the time. Little tryhards.

Don't feel bad. My 12900KS with a $38 FS140 is sitting 5 feet away at 29c.

Nice temps. I'm seeing if I can make any tweaks in the bios to bring the idle temps down some more. Your systems look great (y)
 
13900K
Cooling: Corsair 150 elite (360mm) AIO
Idle on the package is 26c
I do anything like pop a web page while typing and she settles in at 32c Package temp .Fan 2 is my AIO
Ambient room temp is 65 F ( Rec Room in my Cellar)
