For the last few months, this GTX 950 has made some occasionally-loud rumbling noises but usually quieted down shortly after. Earlier today, the fan stopped spinning — entirely.

I dusted out the case and turned it back on at which point the fan started, then stopped, started again, then stopped. Stranger yet, it appeared to be flip-flopping directions. When it does go at full speed, even for a moment, it's doing so counter-clockwise, which seems odd because I don't think that's the way it should be spinning.

I can boot to the desktop and do whatever I like with the system, even enter some games but obviously at an extremely high temperature (close to 100C). Video card itself seems to be fine but the fan isn't. Is this a power issue, a bearing issue, or something else?
