Hello everyone, I bought a used 6800 XT and the fans are completely inactive. They barely spin when the PC powers on. During gameplay the GPU gets too hot and causes performance issues. I've attempted several fixes: moving the GPU out of its PCIe slot and power connectors, checking the PSU cables, uninstalling drivers using DDU and reinstalling via AMD Adrenaline, adjusting fan curves to 100% in Afterburner and Adrenaline, turning off the zero-speed fan mode, ensuring no blockages and confirming fans move freely when shifted. Connectors appear properly seated. I also reinstalled the old GPU which now works fine with spinning fans and full control in Afterburner. I’m considering a refund but want to double-check. Any advice or additional steps you recommend would be appreciated.

It seems Afterburner displays the fan speed percentage. Do you notice a value above zero when fans aren't spinning while it's managing them? Or would it work better to adjust manually using the ruler and press Apply each time you make changes? Edited June 23, 2025 by leclod
GPU coolers come with a different header than regular ones, which is why a converter is necessary. (It’s quite surprising that two or three fans stop working completely at once, making it very likely they’ll all spin.) Edited June 23, 2025 by leclod
I installed it in the lower PCIe slot and the fans began operating. After moving it to the higher PCIe slot, the fans also started running there. This was the third time I placed it in that slot. I’m not sure what caused the change, but it’s good that it’s now working.
