Hey everyone! I recently cleaned up my PC for the first time in a year without using compressed air and closed it back up. When I turned it on, I ran a fan health check using Trixx on my 7900XTX, but it showed 0 RPM for all fans. The fans only spin during the boot-up phase but don't turn on while gaming or under load. I've also reinstalled my GPU drivers several times, and I'm not sure if that caused any issues. Any ideas on what's going on?

It sounds like your GPU is likely in a "zero RPM" mode, which prevents the fans from spinning until it hits a specific temperature threshold. This is pretty common with modern GPUs. You can adjust this setting using software that allows for custom fan curves, so the fans will kick in sooner if needed.
That's a good point, but if your fans aren't starting even when the GPU hits high temperatures, then there could be more to it. It’s strange that the fan health check didn't register any spins at all. You might want to double-check connections or try resetting your GPU settings to see if that helps.
