System boots at 89 C

[Jarthur144]

So, I built my first PC today. It booted up fine, but gave me two errors- one that my CPU was above temperature and another that there was a CPU fan error.

I’m using the h150i elite capellix to cool an i9-12900ks. I have the tach cable plugged into the AIO spot and the other cable plugged into the icue commander that came with it. I also have the fans attached to that commander which turn on when I start my system. So, I don't believe there are issues with the commander or it’s connection to the motherboard. 

My pump also doesn’t show up in the bios, there is no pump speed displayed only an N/A. 

Could my pump/tach cable be faulty or is there something else that would cause this problem? I’m fairly certain the heat block is installed on the processor correctly with an appropriate amount of thermal paste, but I’m more than willing to redo it if that could be the issue causing this, but I don’t really think it is. 

I am planning to go out and buy a standard heat sink to see if that’s able to cool down my CPU and maybe isolate if it’s the h150i that’s the problem.

Thank you for your help :)

The CPU fan error is the result of nothing connected to CPU Fan. This is standard motherboard protection to make sure you don’t boot up without a cooling method. It’s also why you connect the tachometer cable from the pump to cpu fan. It’s not required for the cooler to work.  It’s only there to satisfy the MB safety requirements. It can be turned off in your bios, but I there seems to be a secondary issue. Move it to cpu fan for now as a secondary check. 
 

The 89C cpu temp is an issue and you should get a reading on the AIO fan header. No signal there plus hot cpu means the pump is probably not running. On most AIOs this means we’re done and you need to replace it. However, the Elite series has a more unusual power delivery. 
 

Shutdown the PC and then flip the PSU switch off. Go around the back and disconnect the wide power cable from the pump to the Commander Core. Then reconnect it with the white stripe properly aligned with its mate on the controller. Make sure the SATA connection for the Commander Core is good (fans would be stopped as well if this were the issue), then flip on the PSU and boot normally.

 

If you can get to Windows and open CUE, the H150i Elite Temp in CUE is coolant. With a stopped pump that is going to be near 60C. If so shutdown and send the AIO back as faulty or contact Corsair Support. If the coolant temp is low and the cpu temp high, it could be a contact issue but the lack of a report from the pump on the AIO header suggests that’s not the case. You should feel and hear pump vibrations when you are close to the pump top.

Yep I did make sure the white parts were aligned. I also tried plugging it into the cpu fan port and it still wasn’t recognizing anything. 
 

Trying to get into windows to do anything just leads to a pc crash from what I’m assuming is the cpu shutting everything down from high temps. 
 

I’m planning to return it and get another one. Thank you for the helpful response!

Hi, this is my first pc build so I’m a little confused on what to do right now.

So, I have finished building my gaming pc and have booted it into bios. However, I am running into two problems.

The first problem is that the temperature starts at around 40c and then shoots up to 89c over a few minutes. This seems really for he computer being in idle. I checked and my liquid cooler (Corsair H100i v2) seems to be running properly. The cooler is plugged into the CPU_fan header and it’s two fans are plugged into the Y cable coming from the cooler. Is this the correct way I should I have these cables plugged in? And is there specific settings I should be using bios to make sure my cooler is running properly? In addition, I removed the default thermal paste and applied my own.

Secondly, I am getting a CPU fan error which I am not sure how to fix.

Finally, just some other information. I have not installed windows yet because I am nervous too when the CPU temperature is 89c. Is the Corsair link software necessary to install for my cooler to work properly? As for my parts:
-intel i7 8700k
-asus Rog strix 2730 E
-nvidia 1070ti
-Corsair H100i v2
-EVGA 750w supernova G3
-Corsair vengeance 16gb
-Samsung 960 evo series 250gb ssd

A H100i v2 has a different power delivery than most modern coolers and gets pump and fan power through the motherboard fan header. In the BIOS make sure the header providing power (most likely cpu fan) is set to Full Speed, Disabled, or whatever language indicates a constant 100%. For Asus this is “Full Speed” in the EZ Bios Q-fan section. 
 

See if that corrects the issue. If not, then likely the pump is not working correctly or the flow rate is restricted somehow. 
 

Corsair Link was replaced almost 5 years ago and is may not work properly with current Windows 10/11 operating systems.  CUE 4 is the current control program for the lighting, pump and fan speed. It is not required and the cooler will run from its hardware saved settings without it, but you won’t be able to adjust it either.

No response about my answer.

you may have to go in BIOS and set your CPU fan header to a fixed full speed, to make sure the header supplies a constant 12V to the pump.

If left to default it's possible you have a lower voltage there, basically not allowing the pump to spin at all.
