Gotta agree that the stock fan on the 1950 Pro is loud, esp. under load. But it depends on which brand of card you bought and what fan/cooler they put on it. I have a BBATI card and the fan was terribly loud. Went with a Zalman VF900 and couldn't be more pleased. Keeps temps way down from the stock cooler, looks better, barely takes up any more room (not quite another slot wide), The VFR700 also seems to be a very viable option as Gigabyte uses it stock on their cards. But I'd really think about switching over.
The reason I used the Zalman instead of the Accelero X2 was because I've heard the X2 is a complete bitch to get off if you need to. The Zalman, on the other hand, should be very easy to remove and to reinstall the stock heatsink if you had to. To remove the ramsinks, even if very stuck on, just use a single-edged razor blade, slice off the sink from the RAM module, the use isopropyl alcohol to loosen up what remains and remove. Or a little WD-40 put to the remaining goo on the chip will definitely loosen up the glue left from the RAMsink....don't spray it on, just dab it on using a cloth that's soaked with WD-40.....that stuff loosens up glue very well and let's you roll it off in a little ball of glue-goo....and the chip is clean.
