10980XE hits 110 degrees even on a custom loop

[Nocturn]

I am using an EK velocity water block. However, it is still unable to draw all of the hear from the cpu. Is there something I am missing?

CPU is clocked at 4.8 all core

They can be hot CPUs even at stock and you're running it overclocked quite a bit. If memory serves correctly that is a generation that was soldered to IHS so you're not even going to have delid as an option to try and get a bit more out. Back off the overclock is my best suggestion.

What's the rest? Not going to do much if it goes into a single 120mm rad for example...

What's the water temp?

Quad Slim from EK(Second 3ple got damaged in shipping waiting for a replacement)

Under full synthetic load on CPU and GPU

GPU stays at 58, while the CPU thermal throttles.

Strix 3090 OC

10980xe 4.8ghz

afaik EK SE rads not really good at dumping heat

 

try EK PE, HWL GTS or Corsair XR5

I have to say I think your expectations are too high. 

"at the moment I'm stable at 4.8ghz with a vcore of 1.23 volts on all 18 cores" -From a thread you posted this July 1st 2020 -

 

You want to aim for 1.20v or less v-core. Most custom loops have a hard time with the mighty 10980XE (enthusiast chip) on ambient at 4.8ghz. 4.6ghz is pretty much a good spot for thermals.

 

It's too transistor rich to achieve high frequency on ambient cooling. 5ghz maybe with a chiller loop.

I have actually moved to 1.3-1.4 on all cores for stability. Will the cryocooler help?

I go to 100 degrees, but stay at 4.8.

What cryocooler. There's all kinds of different ones.

 

It won't throttle. Some boards while manually overclocked will remove the throttle protection. You should go in bios and turn it on. You're gonna bake that chip.

You're not gonna get 4.8GHz all core without a binned chip in the sub 1.25v range with reasonable temps man, and you have a single slim rad, that's no where near enough. I have an XE 360 and CE  360 cooling just a 7700K and 980 Ti, when overclocked even that gets the loop warm, a 3090 and heavily OC'd 10980XE are gonna need probably separate loops with D5's and 2 rads each if you want decent temps, or one very large loop with 3 rads. That or extreme cooling, chillers, SS units. As someone who makes chillers and SS units I wouldn't recommend them for daily. 

You're options are

1. lower the voltage and clock speed
2. get more radiators and see if it's coolable then
3. delid the chip (not recommended)
4. use vapour phase change (not recommended but an aquarium pump that won't go under the dew point might work)

You need at least a 360 (and a good one too, not the shitty EK slims) for a 10980xe. You could also probably do with a better performing block, but lack of radiator space and effective heat dissipation plus some bonkers voltages are your problem here.

 

You really shouldn't be pushing Cascade Lake-X above 1.3v in daily use either. If your chip can't do 4.8 at sensible voltages then you need to wind the clocks down.

Is there a cryocooler that you would recommend?

(and to repeat the fat triple just got destroyed in shipping, and I am still waiting on a replacement)

[Slizzo]

You're asking too much from that CPU as mentioned with the cooling you have.

 

I have a 10940X, at 4.9GHz all core, and you, like others said, REALLY want to be below 1.3v on the cores for a daily.  If you can't achieve that you need to back off the clocks and voltage.
