X62 poor cooling

[Genotabby]

Hi, I'm running a delidded I9 7900X at 4.7GHz all cores and 1.25V on an X62 cooler with thermal grizzly Kryonaut. However my temps are 45degC on idle, 61degC with 10 cores loaded and 95-100+ on full load. Does anyone have experience with this kind of setup? I was expecting lower temps with all the x62 reviews I was seeing. Would upgrading to a x72 or H150i get lower temps

wait what where you doing to get 61c for a 10 core workload and then 95-100 for a full load? (95-100 is very high and not good for your system!)

Looking at your idle temps the problem is one or a combination of things.

 

• Your ambient room temp is HIGH
• Your pump is dead
• You are not making proper contact with the CPU
• You forgot to take off the plastic on the bottom of your cpu block
• Your pump isn't properly plugged in for power.

The only thing that's wrong is using an AIO on a big boy processor.

 

Big boy processor requires big boy cooling. I'd understand a AIO on a 7700K/8700K but definitely not a enthusiast tier processor.

 

The difference between a consumer 4/6 core and a enthusiast 10 processor is, as you can imagine, quite big. HEDT processors dump a lot of heat. Most AIOs will not be up to the task.

 

If OP can afford a X299 setup, then they can afford a proper loop. Even if it's CPU only, it'll do a far better job.

 

EDIT: Also get a delid

The system at idle wouldn't dump so much heat to bring his idle temps to where they are currently sitting.

 

Also a 280mm rad with decent fans should be more than up to the task for a 10 core cpu.

Will be moving the pc every few months so no  loops. It is delidded already.

Ambient is 28 degC 

Pump is working with 2600 rpm

Repasted several times and there's the spread pattern

Plastic is removed 

Pump working, can feel the liquid through the loop

Prime95, selected 10 workers and all 20 working for full load

A 17c from ambient temp at idle is pretty high. I would expect idle temps to be within a few C of ambient on a decent AIO. Does the x62 give you a way to monitor your water temps? I would be extremely curious in what your DeltaT is.

 

As far as pure heat dissipation goes you should easily have 350-400 TDP with even low grade fans at a deltaT of about 10c

 

I mean your impeller could be damaged. Meaning you feel coolant flowing, you hear the pump, but the flow is really low. So low that heat is building up faster around the cpu block than it can be carried away. Which is resulting in higher than normal temps.

 

I would personally reach out to your AIO manufacturer and talk with them, chances are they are going to recommend an RMA.

Although I don't think this is the cause, just going to put it here. I've always religiously spread kryonaut manuall as per the instructions. While its been shown time and time again that it doesn't matter, just another variable to really eliminate.

 

As AngryBeaver says above, water temps according to NZXT cam would be of incredible value since the CPU should be within a couple of degrees of the water temp for idle.  My idle water temps are a couple degrees higher than ambient temp, so that makes my CPU warmer than ambient by a reasonable amount.

Liquid temps are about 37 degrees at idle and 45 under 10 cores load
