GPU fans are at their maximum speed.
GPU fans are at their maximum speed.
I searched thoroughly and followed all suggestions, yet BST still occurs periodically—it's quite bothersome. The system performed well after assembly in October, but over the last three months I've noticed this issue. I don't recall any changes, except possibly a component being moved. My setup includes an AMD Ryzen 7 7800X3D, MSI Suprim Liquid 4090, Asus ROG STRIX B650E-E, and two sets of Corsair Vengeance (16 GB each) DDR5-6000 CL36 memory (64 GB total), plus a Seasonic Vertex 1200 ATX3 PSU. I've used various 12VHPWR 16-Pin cables, including the ones from Seasonic and CableMod; no signs of damage or melting were found. All updates were applied: Windows is current, Nvidia drivers and GPU firmware are latest, and the BIOS is up-to-date. The GPU is securely installed in the main PCI slot. I ran memory tests via Windows 11 and MemTest86—both passed without issues. The RAM is firmly seated, and I rechecked all connections, verifying the motherboard, GPU, and PSU. The PSU is operating normally.
Have you experimented with the adapter? The 1:1 12VHPWR model caused the most problems compared to others, especially the fan slowing down when idle. It might be related to the sensor pins.
