Question Faint Beeping Sounds

[In2Photos]

This should be a fun one to figure out! 🙄

I am having a faint beeping sound that I notice while playing games. It sounds exactly like a UPS has lost power, 3 beeps about 1/2 a second apart, but it isn't my UPS as I only hear it through headphones, no speakers are connected to my PC. Here is my hardware:

MSI x-58 Pro Motherboard
i7-920 OC to 3.6GHz
24GB DDR3-1333
GTX-1060-6GB

My headphones are Razer Kraken, plugged into my Razer Black Widow Elite keyboard using a 3.5mm jack. The keyboard is plugged into the back panel audio ports of the x-58 Pro.

I only wear the headphones while gaming. Occasionally I will connect a small speaker for watching YouTube or something instead of my headphones, but I don't hear it on that. I'm thinking it may be some sort of alarm, perhaps temperature related that only occurs during gaming. My CPU temps are 75-80C, GPU hits 70C.

Anyone with any experience like this?

Thanks.

Do you have a "Beeper" (piezo speaker) connected to the mobo? If so, it may be a temp or fan alarm from the BIOS. Probably temp. Either adjust your temp alarm settings in BIOS, or clean out your heatsink and PC (probably pretty dusty in there).

No speaker connected to the mobo. Unfortunately there is no setting in the BIOS to adjust for any alarms, if in fact there even are any alarms. PC is clean actually. I recently cleaned and re-applied the CPU and northbridge thermal paste to try and reduce temps after overclocking my ancient CPU to try and get some additional performance out of it util I can upgrade everything. So the insides are all clean. I've added some fans and adjusted CPU voltage to try and get the temps down as much as I can.
