CPU Detection Error

[Zenoz]

Just built my first custom loop setup and everything seems to be working fine but on booting I got a CPU fan detection error, I see other connectors on my motherboard but they’re all 4 pin and my cpu water block is a 3 pin.

 

The current spot it’s plugged in is called “CPU_OV ADD GEN2_1”?

 

Motherboard: Asus z790-E 

The temps started at around 47c and have been steadily rising in bios as I left it running(57c at the time of writing this), I expected some increase but this seems like a lot so the issue is definitely there especially since I think the volts for the cpu seem low from what I’ve seen (1.305V i9 13900K)

 

I’ve included photos of the connector and where it is currently plugged in

 

Not sure where else this would go as the headers have 4 pins? Thanks would appreciate the help

I don't know that plug, I don't know much on water cooling though

On my mb, the pump header is the same as all the fan headers and this isn't it.

Anyway, if the issue is the CPU fan detection error, than you could just connect a random fan to the cpu fan header.

Thank you for the response

 

So I've done some research since and it seems like the plug is called "D-RGB 3 Pin Connector 5V Digital LED Header" which confuses me even more and makes me question if its not just a RGB cable that doesn't control the actual cooler. Prior to knowing this I ordered a cable yesterday that I thought would fix the issue (I cut the outside black plastic as it was in the way) but it doesn't even seem to fit? Even more lost now.

 

Whilst testing this and just letting it run, the CPU hit 65C in like 20 minutes starting from mid 40c, I know my CPU runs hot and this is prior to me changing any settings but I don't even an operating system installed and this is it just sitting on the bios screen, the temperature leads me to believe that the cooler just isn't working, the motherboard temps etc all run fine.

 

My water block is the "EK Water Blocks EK-Quantum Velocity² D-RGB CPU Water Block For Intel 1700"

CPU: i9 13900K

 

Does anyone know if I'm missing some sort of cable or something I need to plug in (I checked the box and looked at pictures and there doesn't seem to be anything)? Hope any of this information helps

 

thanks

I wonder if you know what you are doing.

So you seem to have a waterblock with some RGB lights. We don't care about those lights for now.

What we need is a pump for water flow, some fans on a radiator for water cooling and some water flowing, do you have those ?

Of course, I have one big 360 radiator with 3 fans then I have a smaller one with 2, both are connected and the fans are all spinning.

 

My pump is also connected and has pumped the coolant through the entire loop. All my temps are fine except for the CPU.

 

The only reason I looked at that cable is because it was the only cable that I had with the waterblock so I thought the error was regarding that.

And you have the pump connected to a PWM Pump/Fan header

and one (array of) fans connected to the header named CPU Fan ?

 

By the way the RGB header seems to be located just on the right of those (Yes that ADD GEN2_1 should be it)

 

(Nice board !)

Thank you for all your help, I’ve actually managed to solve the issue by stumbling into it out of frustration. The whole cpu cooling didn’t make much sense as it’s a water block anyway so the pump is what really matters but the error confused me.

 

In short: When messing around my fan RPM, my bigger set of fans with the radiators didn’t actually adjust its PWM but the other ones did without any problems, I checked the lian li controller and when I disconnected the RGB, all of a sudden the PWM worked, I got no clue on why the RGB was causing this as the RGB worked but for some reason it’s breaking the PWM (still haven’t figured out why, even a static RPM won’t work whilst RGB is connected)

 

Managed to install the OS etc without any issues and seems to be working fine apart from the XMP, looked up several tips and stuff from people and no matter how much I change the voltage, profiles, PMIC,CL, just won’t work even if I’m using less than the advertised speed

 

My ram is the Kingston 6000 MTs DDR5 64GB, works fine without XMP but would appreciate it if you had any insight regarding those 2.

 

Thanks for all the help
