Question My PC makes a wierd crackling sound when gaming.

[Xenokal]

Hello. My PC seems to make a weird static like crackling sound when gaming. This seems to only happen during the summer months, as it never does it during the rest of the year. I thought it may be the GPU so I applied fresh thermal paste. GPU doesn't go above 82c . When the PC is idle, the sound stops completely. I thought it could have been the PSU so I swapped it out with a newer PSU, the sound persisted. I listened around a bit and the sound seems to be coming from the rear IO panel. I was unsure entirely so I decided to ask if anyone else may have had the same issues or similar.

System Specs:
RAM: 32GB DDR4 3200mhz
CPU: Ryzen 7 5800x
GPU: GTX 1080 (other GPU keeled over so I am using old faithful)
MOBO: B550M Aorus Pro P
SSD1 Samsung Pro Evo 1GB
SSD2 Samsung Pro Evo Plus 2GB

Have you tried changing the mains lead connected to the power supply?

It's difficult to diagnose without actually hearing the sound. Is it possible for you to upload an audio file so we can listen to the actual sound?
