CPU Fan Error - H100i V2

Hi guys, 

 

I've recently replaced my motherboard with the same type I previously had (had an issue with the old one). I've installed everything and plugged everything in and upon startup I get a warning "CPU Fan Error". 

 

The H100i fans are both spinning, and the cosair logo illuminates. The fan speed doesn't appear  in the Asus bios. CPU temperature rises a degree every few seconds - I've turned it of before it gets too high though. I've tried using the CPU fan header aswell as the optional CPU fan header, same thing happens though.

 

What's causing this and how would I fix it? 

 

Specs 

Case: NZXT Noctis 450 (this has a fan hub although J believe I have the config right)

Motherboard: Asus Z390-E 

CPU: I7 9700k 

Cooler: H100i V2 

 

Thanks in advance!

Are you sure you plugged the H100i into sata?

As per the NZXT instructions, the CPU cooler connects into the hub on the back. And the hub connects into the CPU fan header. Which I've done. 

 

I've also tried just connecting the the h100i right into the fan header but the same thing happens. Possibly the coolers died?

Turn off the fan monitoring in the bios for that cpu header. 

 

Or lower the reading minimum if anything is being reported. 

 

Could still happen if it doesn’t report in time for the post.

If I was to turn off the monitoring, I could boot into windows right?

 

That wouldn't explain the temp rising to 60+. I'm not sure of the peak it reaches I haven't let it go much further past 60.

Sure, you wont get the warning. But if the pump is plugged into the cpu header and its not reporting a speed the software is doing its job. If the cpu is at idle, being that hot is an issue.
