HELP!!? CPU fan error for a noob

[menuau]

Hi,

I have the following parts in my new rig:

- ASUS ROG Crosshair hero viii wifi

- AMD Ryzen 3900X

- EVGA 2080 Super

- 64 GB DDR4 RAM @3600Mhz

- Corsair 120mm AIO (name escapes me)

- Corsair RM 750x PSU

- 250GB SSD hard drive (Samsung EVO)

- 6TB HDD (Seagate)

- 2TB NVMe SSD (WD Black)

 

I was powering the rig down for transport, but forgot to power down the PSU before unplugging the cable from the wall. Now I can't seem to power up the PC and when I do, I get a CPU fan error on the boot page after the ROG logo. 

 

Please help?

Hello and welcome.

 

What happens after that error comes up?  Are you able to get into BIOS?  And do you have a fan connected to the CPU Fan header?

Your fan or pump (I don't know what you have plugged in to the cpu fan header) just became unplugged probably whilst prepping it for transport. So check that and that should solve the problem.

Hi Nick Name + Jaslion,

Yes, I can get in the BIOS after pressing F2 (the American Megatrends logo lists the hard drives, as well as the peripheral). The boot options are either my Samsung SSD, enable, and disable (I think), and the boot override is either on my NVMe (which has literally nothing) or disable. 

 

Also, I took extreme care of the case during transport and the fans, given the overall cost of the build. I laid it on its back and was careful bringing it and there's nothing seemingly unplugged after putting a flashlight to it.

Or if you're intentionally not using the header your can set it to Ignore in BIOS.

So does this mean you cannot boot into Windows?  Is that what the problem is?

You are fine, you have an AIO cooling our cpu so you can disible the cpu fan monitor in BIOS as long as you have the pump monitor enabled.

Not automatically, no. I have to go through the BIOS to get it done but every time I restart it says that same CPU fan error. I did notice that it also counted my keyboard + mouse twice on that American Megatrends page.

 

A friend went in the C:/ black window (CMD centre?), and did chkdsk for all my hard drives and found no errors.

 

Sidebar: my Samsung SSD drive is where my Win10 software installed, the NVMe is brand new (empty), and the HDD is for videos, pictures and saved games. I also did not overclock or RAID anything (I probably wouldn't know how to anyway )

It will give you that error until you use that fan header or ignore that fan header.  I've posted a picture a couple posts up in the thread.

Okay. I'll try that. Does that mean I'll have some numbers here (see pics attached)? It's odd because I see the fan speeding.

OMG, Thank you everyone!

It works and boots up normally! I was terrified I fried my PC and was confused it said there was an fan error whilst fans were fanning (maybe not at the right speed). 

 

I am so relieved! Are there any issues with this solution I should be keeping an eye for in the future?

As long as all your fans are plugged in where you want them then that's the fix to use.  I don't use my CPU Fan header either.

Do check temps to see if all is still running at the correct speeds to keep them down. You may have had a bios reset by accident causing the issue.
