I assume you mean the fan and that it doesn't spin. Which is what I suspected (and suggested to you) all along.
The only long term solution is replacement. It is usually not possible to replace just the fan, so you will be looking at replacing the entire GPU cooler assembly (the fan as well as the heatsink) with a third party one. The good news is that many of the third party coolers deliver either better cooling or quieter cooling, or both.
You didn't mention what card you have. These guys
make high end, quiet coolers for just about all of them, although note that these take up the slot next to the graphics card and that could be a problem in a system with all card slots used.
If you would prefer something more conventional, more like the stock cooler, the Vantec Iceberq
comes in two sizes that cover most modern graphics cards. Unlike the more elaborate kinds, these are frequently carried by local computer retailers.
The usual problem with fans is that the cheap sleeve bearings have seized up. You can tell that is the case by trying to turn the fan rotor with your fingers -- if it doesn't turn freely, it may be worth trying to lubricate it as a short term solution.
The bearings are under the fan and hard to get to, but you can try to get a liberal amount of WD-40 or some mineral oil in there, while turning the blades back and forth with your fingers. You will know it got to the right place when the fan starts to turn freely. If it still doesn't work when powered up, then it probably has burned out and there is no temporary fix for that.
In either case, it still should be replaced ASAP. The benefits of lubrication do not last very long.
