my new gigabyte mobo also has an annoyingly loud constant buzzing sound, extremely slow post and comically buggy bios. a few friends had to rma their gb mobos because DOA, loose ram slots, instability etc... also my gpu is gigabyte 3060ti and it has a lot of problems too, nvidia is mostly to blame but i think it's gigabytes fault that the fans minimum speed is very loud, around 1200 rpm. the fans are normally off but the temps climb to around 60c even when idle, then fans go WROOOOOOM for a few mins and then turn off. my new case has air intake at the bottom, 2x 140 mm fans blowing right into the gpu but still the damn gpu fans sometimes turn on even when just watching a video. and it's not because of dust, the heatsink is perfectly clean.
