Your card will most likely never see the stress put on it by Furmark, so it will probably never see those temps. If it does, however, yes it could be the reasons for the BSODs. I seriously doubt it will though. Furmark is designed to run your card as hard as possible. But, in my opinion you did the correct thing. The rep on the AMD series has been the run excessively too hot, with the reference cooler. Some have come out with custom cooling which makes them much cooler.
If you have a utility that came with your card, I would use it and set a custom fan profile and run it with the fan speed increased considerably. If you don't have a utility to do that you can use MSI Afterburner which is primarily an overclocking utility, but allows a custom fan profile. I have it in another rig and have not overclocked that card, but I do use it for a custom fan profile and monitoring.
Try this and see what difference it makes. Download Ungine Heaven 4.0 Run it with the basic preset and see how hot it gets. If it seems to do OK, run it again after the card cools down with the Extreme preset. It has a benchmark function if you want to use it.
I would suggest you watch your Graphics card and CPU temps any time you are doing anything stressful with them. I set mine for on screen display which tells me, among other things, the temp and fan speed of my card when gaming.
