Random Audio chattering/freezes pc for about 3 to 5 seconds then resumes

[Banshee4711]

System:

EVGA X390FTW  motherboard

32gb Optane module

Samsung EVO 860 SSD

4TB WD Green HDD

8TB ReadyNAS

EVGA RTX 2080 TI FTW

4 port PCI USB 3.0 card

EVGA 1000 Watt Modular power supply (forget the exact model, used to have 2 GTX 1080s in SLI wanted more juice)

Noctua NH-U12S (if i recall) cpu cooler

Intel 9900k CPU

after starting a game like WoW, the game loads, and sometime within the first 5-10 mins it'd sound like a chainsaw, and lock the system up for a few seconds, then resume (it never rebooted).

 

I previously had an AIO and then a Noctua D15s, and had the same problem.

 

so far I think I may have solved this problem, but its a bit late, i'll retest tomorrow. I wound up disabling the onboard Realtek audio on the motherboard, and replaced it with a External USB module, the Soundblaster Omni 5.1.

 

The case still runs hot, even with the 12s coooler on (new case doesnt support the d15s height, around. i have the cpu coolers fan facing in the right direction, in a PULL configuration, instead of pushing through the the heatsink. for some odd reason. all other fans are blowing the right way. CPU idle seems to be 60c OC'd at 4.9Ghz. 

 

If I cinebench 20 it, i get to 93C with a 4652 score

 

edit: changed cpu fan to the right side, and idle now is about 40c .. sill havent seen the stutter problem though since I just disabled onboard audio

blah  it started again. tried updating realtek's driver for the motherboard. at least with the USB sound it just goes silent during the hang. anyone else have this problem?

sounds like the flawed windows update....KB4515384. try uninstalling it if you have it and see if that fixes it.
