Hi, my 2 year old (first POST and windows install March 8 2020) PCs AIO has begun acting up in the past few weeks, randomly loosing power and failing during heavy gaming sessions.
The Common indicator of this is the USB disconnect noise as the system loses the connection to the pump, followed by a extreme spike in temperatures.The Decorative EVGA led on the pump stops lighting and the two Radiator fans stop turning.this has yet to happen during idle loads.This has happened twice in the same day and a total of 5 times in the past 7 days.This issue instantly resolves when i restart the PC, until it occurs again.
I have yet to have the CPU overheat long enough to shutdown the PC but its only a matter of time before it goes unnoticed.
This has also seen a few other odd behaviors, such as a single Case fan losing PWM control and deciding to go full bore, unresponsive to software controls. however this only occurred once and resolved on Restart.
The night before this started there was a lightning strike within a mile that managed to trigger the lights on my USB mouse, requiring me to turn on the PC to cycle the Keyboard and mouse to get to turn back off. I do not know if this is releated.
The AIO is a EVGA CLC 280mm.
Computer specs:
i9-9900k
Gigabyte Aurous z390 Pro Wifi
Zotac 3080ti Amp Holo
2 NVME ssds (1tb & 2tb)
2 Noctua IPPC 140mm Case fans (front intake) + one 140mm Coolermaster Case fan (rear exaust)
Seagate 850gold
Randon DvD drive from older computer.
Seriously Considering putting in a Noctua NH-D15 and running the CPU fans off a seperate Controller atm if i cannot determine AIO failure or Mobo Failure. The AIO has preformed well and never allowed my CPU above 60c. Also Considering buying a Molex to 3/4pin adapter and plugging the Pump directly into the PSU to test if it fails reguardless of where it is plugged in.
EDIT: 6/27/2022: Second Pump header on mobo produced random disconnect.
