looks like they updated the fan for one that had less blades to it, as your's has 7 compared to the reviewer's 13 (both a strange number nevermind)
If you've purchased the board recently it is highly likely that it'll be a r360 based card (underclocked 9800xt) rather than the original r350 that was the 9800 series. It's also a smaller heatsink it would appear (why i dont know as they had issues with the reference cooler before). The fan should be able to spin with a little effort and have a distinct pulse like feel to it.
Out of interest is there a temperature read out in the driver control panel somewhere (indicative of a r360 base core).

If you happen to have a case fan to hand it maybe worth directing one directly at the card leaving a few cm's of clearence to see if that helps with its stability for now.
