Can anyone recognize this CMOS beep code coming from my ASUS P6X58D-E MOBO?

My Homebuilt computer has started beeping out of the blue. It's not heat related, I went down that rabbit hole. Everything is chill.

Below is a recording of the beep patter I get most frequently, but sometimes I get others too. I have reseated everything inside the case, and it helped. For a single day.

Now I have been without beeps for another 24 hours + but it has happened before. Soon it will beep again.

I will appreciate any lead to solving this issue. Thank you.

To me it suggests something to do with the fan monitoring of the motherboard.
In relation to one of the fans of your system dropping bellow the rpm speed the fan is set at in the bios to trigger an alarm to say the fan as it sees it is as broken due to the lower rpm it is spinning at.

Go into the bios setup of your motherboard and check what the trigger point is in rpm for fans you have connected to your system.

Lower the Rpm value set to trigger a audible alarm.
You can tell if this is the cause if the beeping happens right after you first power your system on and the bios test sequence is started.

And if it continues all the way to windows, and while in windows.

Rpm speed of fan too low spinning slower than the trigger point in...

It can also suggest that the pump on the water cooling loop is failing or has a fault since it can be connected to a fan header of the motherboard so check what rpm the water pump should be running at in rpm.

The pump can be a fixed rpm, or can be a variable pump where the rpm can be adjusted on a Aio cooler or custom loop setup.

To be safe check it is operating at it`s rated rpm speed if AIO.

Very good lead, thank you. I am going to try this as soon as possible.
I already chased the fan speed as a possible issue, but that was when I thought the problem was in my hardware fan monitoring device (whatever it is called). I never looked in the BIOS for the fan speed.

For the record, today not a single beep. It's been now 24 hours without a beep. Last week it sounded like an aviary in here. Nothing has really changed, but if you are right, then it's possible that a small temperature difference may trigger the alert.

By the way, should I change the CMOS battery after 6 years of duty? It's one of my possible culprits, but the date in the BIOS is pretty solid. I was thinking of buying one at least so I could be ready.
