CPU Fan Error Question

[Harthelos]

Hi guys,

My board is ROG Strix Z370-E Gaming and just 2-3 days ago I had a CPU Fan error which prevents me from booting up.

What I did was, I went to BIOS and just "IGNORED" my CPU Fan instead of it being "MONITORED". Given I don't have anything running through that port as I'm using an AIO cooler connected via CPU Fan Opt, I thought this was the only safe way of booting up.

Anyway, I have 2 questions:

1. Why did all of a sudden, I had a CPU Fan error? I never had it since and I'm running this rig for about 3-4 years now. - if more info is needed on what are the things that are connected to my PC are, just let me know and I can provide.
2. Whenever I reboot/restart my rig I have to go back to BIOS and redo what I just did of IGNORING the CPU Fan. - Do I have to do this every single time I turn my PC on moving forward?

I know my rig is kind of old and someone told me that my AIO pump which is Corsair Hydro Series H100i could be bad but I just checked on the iCue and below is what is displayed:

Fan running at 1500rpm on idle
and pump is at 1900rpm on idle with a temp of 36.50c

 

Do bad pumps detect as CPU Fan error?

 

TIA

edit: might have posted in the wrong section, if I did, can some mod move this to the appropriate section? Thank you so much.

Pull the cmos battery and check it's voltage. If it's under 3.0v, replace it.

[Harthelos]

Oh, I actually don't have any ideas on how to do that. Once I've pulled the cmos batt out, how do I check the voltage? Or do I pull it out, put it back in and check the voltage(which is where btw? Inside BIOS?)

 

TIA

Yep, this is quite common actually. My Corsair H110i GTX did this about a year back.

This is sometimes fixable though, a simple disassembly of the block could reveal a clogged pump, which can be easily cleaned.

 

As seen here:

Early model Corsair AIO's have this issue quite frequently after years of use.

I actually don't have his symptoms though. My temps are clean and never goes above 100 degrees. I think it never climbs up to more than 50-55 degrees Celsius.

 

I also have no power issues wherein it automatically/randomly shuts down my rig.

 

I'm so confused as to why I have a CPU error when iCue software says my pump is running okay.

you need a voltmeter to check the voltage of the battery. something like this one. LCD-Digital-Voltmeter-Ohmmeter-Ammeter-SDL445616116-5-9dfb4.jpeg (1100×1100) (sdlcdn.com)

 

did you have the pump above or below the rad?

[Harthelos]

It's an AIO, no separate pump other than the heatsink itself. The rad is situated in the front of the chassis, oriented vertically.

Quick question:

1. Whenever I reboot/restart my rig I have to go back to BIOS and redo what I just did of IGNORING the CPU Fan. - Do I have to do this every single time I turn my PC on moving forward?

No the bios should save the setting.
