I have an EVGA Geforce GT 440 that I bought a few years ago from Best Buy, it has been a pretty decent card for a budget buy (about $100 when I got it). In the last month or so, though, I've encountered a problem with the fan that causes the GPU to overheat to the point that it crashes my computer...have seen temperatures near 107 degrees celsius (how it hasn't killed the card outright is a miracle on its own).
The fan simply refuses to spin. Thing is, though, it doesn't seem to be fried. At first I'd noticed I could manually spin the fan with my finger to get it going again, which led me to believe it just needed a thorough cleaning and maybe some WD-40 to get it running again. Took the fan off (which is a pain because of the way the stator screws back onto the heatsink), cleaned it out thoroughly with a toothbrush to get the gunk and dust out and sprayed some WD-40 into the small aperture between the stator and the blade itself. I see a lot of people say "you can take the sticker off the top and the bearings are exposed beneath," tried that, no such luck. Top is completely solid plastic...the only option there was for me then was to spray it into a small fingernail-sized opening between the blade and the base, which I kinda felt was a risky venture because there was a small, exposed IC and circuit board (which I would assume is for the fan control circuit from the GPU) but it seemed to work flawlessly afterwards.
Unfortunately, it has started up again...same issue. I can feel the small motor driving the fan vibrating so I know the fan itself isn't completely burnt out, but there is no motion whatsoever. Anyone have ideas? I've got a small desk fan blowing into my case (also a bad idea, I know) to keep the temperature down, but it isn't a very reliable long-term solution. I've also in the meantime disconnected the 2-pin connector for the fan from the GPU out of an abundance of caution.
