Question CPU high temps - low usage ?

[Kingcrusi]

Having some cpu package temp issues curious if I’m missing something.

Fresh startup. No programs running and the cpu is at idle 3% and sitting at 60-70c. I think that is too high but I could be wrong. I have clocked it down from the default 57x to 55x using the intel utility. When at 57x it idles closer to 90c.

I have fans at max speed always and pump at max speed.

I did a test today. I pulled the cpu block and cleaned off the thermal paste and put a fresh on it to see if that’s would resolve the issue. Sadly no change.

It is a custom build. And custom water loop.

Double radiator running 3 120’s each.
One rear exhaust.
Water goes from pump -> gpu -> cpu -> radiator -> radiator -> pump

Motherboard - ASUS ROG Maximus Z790 Dark Hero
CPU - Intel Core i9-14900KF - Core i9 14th Gen 24-Core
Ram - 64gb ddr5 6400


CPU block - CORSAIR XC7 RGB ELITE LCD CPU Water Block

Hopefully I answered everything that might be asked.

Welcome to the forums, newcomer!

What pump are you working with? As for your cooling setup, what is the make and model of your radiators and the fans on said radiators?

 

[Kingcrusi]

Thank you.

So in the current setup.
pump - LIAN LI O11D Distro-Plate G1 Designed by EKWB with DDC 3.1 Pump LGA 1700

Double radiator both - Thermaltake C360, 27mm Thick 360mm Long, High-Density Fins, Copper Tubes Copper Radiator CL-W228-CU00BL-A

And all 7 fans are Corsair QL Series, Ql120 RGB, 120mm RGB LED Fan
3 on each radiator and 1 back exhaust.

For flow. 3 bottom fans pull through the radiator up. The top radiator pulls air up from in case to exhaust out. Final fan is the back fan that is set to exhaust.


To note my concern on the temps. This is my second build so my assumptions are based on my first build that would idle at 30c while this one as mentioned above idls at 60-70c.

Did you flash latest BIOS with last Intel microcode ?
That CPU is on endangered list from Intel, some damage may have already occurred.
Also forget about CPU temps on earlier generations, 90c+ is pretty well standard on top models nowadays. Idle temps are not a concern and could be lowered by running pump at 100%

Okay wow. Good to know on the temps for idle. I was thinking that was an underlining issue overall. I still have a heat issue. I currently have to have the case walls off with a large fan blowing in additional air constantly to game on the computer. If I close the case. Maybe 10 minutes in. The computer shuts down due to overheating. So something for sure isn’t working properly with heat dispersion.

I will check the bios again. I flashed it 2 weeks ago to the latest bios. I will check again on the bios for sure.

I do currently run pump and fans all at 100%.


I have had trouble trying to turn on xmp. Ram does support it. But if I enable it. Pc crashes constantly. So it’s currently disabled. Possibly right on the chip already damaged unless running xmp is a motherboard thing. Still learning the ins and outs of everything.

New BIOS with fixed microcode came out only couple of days ago. That's one you MUST use.

Awesome. Wasn’t aware it came out. I’ll get that done today.

Okay I applied the bios update. It's now running back at default clock speed. Still running at 100c non stop when anything is running. But on a different note the pc is running so much better with bios update. Also when I say 100c. That is just what all the displays and programs max at when it comes to the temp.

But looking at temp though still. It's sitting at 100c non stop with the double radiator and a large vornado fan pushing extra air flow over the radiator to keep it from overheating and shutting down.

At this point, something wasn't installed correctly along the way.

Water goes from pump -> gpu -> cpu -> radiator -> radiator -> pump

The order doesn't matter too much - at least, not to be seeing results like this.
That's why I suspect the problem has to do with the installation.
Post a picture of the loop - side panel off, please. One of the custom loop experts may notice something off that way.

For sure Phaaze88,

I tried to get 3 different angles trying to get the full loop in view. If i need to get different angles or close ups just let me know.

It's all soft tubing for now. But I will upgrade to hard tubing once im sure its fully working as expected. But I don't see changing the tubing from soft to hard being a factor in the system. This was just my first custom loop attempt so felt like soft tubing was a better option to learn with.

Something is wrong with your configuration. I am using an air cooler with my 13900KF, and my temperature is better when idle.

If I were in your position, I would disconnect the pump to GPU to see if anything is getting better.

Okay. I have some new fluid arriving tomorrow. I’ll swap it all out and remove the gpu. I’ll check back in once I can retest without the gpu.

Radiator on the bottom, not best place even for inline serial cooling system.

@Eximo
Thoughts?

 

[Teknoman2]

Stupid question but someone has to ask it. Are you sure you removed the plastic cover of the water block you put on the CPU?

 

[Eximo]

I would also think there is some contact issue with the CPU. I don't recognize that CPU block, not intended for a delidded CPU or direct mount or anything like that?

Did you install one of those CPU contact frames? If you have to take it apart anyway, you might as well, shaves a few degrees off. Thermaltake one is cheap and it could very well solve the problem if the cooler is overly tight and bending the motherboard.

Understood. I do have a new plate coming in as well. Since the default cpu clamp can cause bending for intel chips.

I’ll will be replacing the thermal again when I recheck everything. So I’ll also confirm for the plastic. Hey nothing is stupid at this point. I could have easily made that slip this time.

Really? Looking at Techpowerup, gaming temps are in the 70c area. 90c at idle is defo wrong. I do think idle temps are an important indication of cooler issues. I also think this must be some contact issue. It shouldn't be idling that high. At high load, absolutely the CPU will easily go past 90c.

Within reason of course, also depends how idle it is but to be higher at idle than under load ?? to me it looks like slow pump and maybe under powered or bad water flow.

Yeah, i think you might be right
