i160 CPU coolant temperature strange behavior

[Poluekt]

Dear friends. I noticed strange behavior of the system recently: sometimes the temperature of CPU coolant instantly rises to about 60 degrees C and keeps at this level (floating from 58 to 61) for some time, 5 - 20 minutes, then goes back to normal. The LED lighting gets blinking red and the fan goes to 100%. No other symptoms detected, neither this behavior is connected to any activity. OS independent: if I restart the PC during this symptom is active - the LED indication and the fan speed keeps red\100% even while the system is loading\rebooting. The CPU core temp remains normal, either idle or under heavy load.

 

Have anyone seen such things? Looks like coolant sensor gone crazy.

When you say goes back to normal after 5-20 minutes what is normal temperature for you?  What temperatures do you expect while underload//idle normally?  Restarting with 100%/red on boot has been normal in my experience unless you let completely cool prior to restarting.  Not quite clear on your concerns without more information regarding what you normally have experienced otherwise.  You have not had the CPU coolant rise to 60C before even under load?  If not what temps have you noticed it maxing at prior underload?

Normal is about 30-45 degrees depending on the load. During normal operation the coolant temperature logically depends on conditions and behaves like it should. Let me try to explain: 

The PC is idle, CPU load 3-5%, core temp 45, coolant temp - 40, fan - 400rpm. I do nothing, then suddenly coolant temp instantly rises to 60. Core temp remains at about 40-45. The system starts blinking red and starts the fan to max speed. In some time it instantly gets back to normal. I will get the video next time.

I never saw my CPU coolant higher than 52 degrees. Never ever. GPU coolant may reach 60 at some high-load cases.

[zguy85]

Wow yea I would agree seems like a sensor issue possibly. Try reinstalling ICUE/any drivers related to pump/BIOS for MBO?  Also check connection to MOBO.  I would start there probably.

[Poluekt]

Thanks, bro. Will do.

2 weeks ago, for the first time, my i160 start to shows this problem too. I think that is related to some ICUE software update.

[Poluekt]

Thanks for the info. I am trying to reproduce it. Takes a while...

Hi @Poluekt

Which version of iCUE are you running?

For best results on the i160 please ensure you're running 3.38 (downloads are on the relevant store page - same iCUE for all Corsair ONE variants of that generation)

I was using 4.19.191. It updates itself to the latest version from time to time. Will try rolling back to 3.38.

Reverting to iCUE 3.38.88 didn't help. The symptom remains.

 

I will now try to check the hardware. Will remove the cooler, clean the dust etc.

I checked the hardware. I removed the cooler, changed the thermal compound. There was no dust. Now assembled everything back and the issue occurred at once.

Could it be a liquid cooler hardware issue? An air bubble?

Not sure if you have done it already. It was suggested earlier, but have you check all the connections? So the sensor cable to the motherboard and to the pump. Just to make sure that it's all connected properly. Maybe disconnect and re-connect the sensor cable (both from the pump and motherboard) and see if that does anything.

Did that. I disconnected the usb and the two out of three slim cables. All the same, the symptom occurs from time to time.

Hi @Poluekt

Try this method
https://help.corsair.com/hc/en-us/articles/360025166712-Perform-a-clean-reinstallation-of-the-Corsair-Utility-Engine-iCUE-

And update to 4.20 using the latest iCUE download link

[zguy85]

@Poluekt any more information?  Were you able to either resolve this issue or find out any further information?  I to had a similar issue but that was before I replaced the TIM between the processor IHS and cooler plate.  Wondering if this is a factory issue.

[Poluekt]

Dear, I have been on a vacation, will try to reproduce the issue after I am back home next week. Will update you guys, thanks a lot!

[Poluekt]

Guys, I did a clean uninstallation of ICUE, used the link provided by Corsair Mordred. The issue occurs with no iCUE software installed at all: the system sets the fan to 100% and flashes the red lights on the case. Seems its hardware..

[Poluekt]

I will perform a clean windows installation and see if it helps. It did affect the cooler behavior last time when I had another issue with fan speeds.

Edited February 27, 2022 by Poluekt

[Poluekt]

So, after a clean windows installation the issue is still there. Any recommendations?  Pump replacement?

[zguy85]

@Poluekt So I have same issue and only way I found around it is to DONT use default cooling setting in iCue.  You have to Custom set it.  I found 70-75% to be a good place without being too loud.  Corsair... please address this because non savy customers will be having lots of problems.  Let me know if this works for you, if so I'm going to start a thread addressing this head on.

Well, it still blinks red which is annoying.. 

[zguy85]

@poluekt Give it about 5 minutes once set takes some time for that % to kick in. Let me know.

[Poluekt]

@zguy85, just to be sure you understood me correctly: the issue is not in constant wrong fan speed. The problem is that sometimes the temperature of CPU coolant jumps to high values and the system automatically sets the fan to 100% and flashes the lights. After some time the temperature gets back to normal together with fan and light.

I will set the fan to custom and wait for the issue to reproduce anyway.
