Expansion Slot Fan running at high speed after installing NVIDIA Quadro 4000

I've noticed that after installing the new NVIDIA Quadro 4000 for Mac on my Mac Pro with Mac OS X 10.6.7 with the newly released NVIDIA drivers (03/22/2011) the Expansion Slot Fan is running at a VERY HIGH speed (between 1,200rpm and 2,100rpm), if I go back the the NVIDIA GT120 everything will be normal with the Fan speed (around 800rpm), does enybody have experienced the same issue ?, thanks

Mac Pro, Mac OS X (10.6.7), 24GB + SSD RAID 0 + Nvidia Quadro 4000

Thanks for clueing me in. I assume the card's fan is working, not overworking and isnt' dealing with dust under the housing to cause trouble..? you have had it for awhile now. Maybe no warranty but wouldn't it be nice if it could be covered by and replaced if the card is acting abnormal or not properly?

High fans under load to move heat out or to loosen up fan or bearing and expell dust.

I just took it out of my Mac Pro 2008 and it was quiet. I believe the high fan noise has to do with putting this card into my Mac Pro 2010 2.93 12 core. So though possible, doubtful that the noise is endemic to the card. So I don't think the card is defective but something in the new Mac pro is making it go faster (I think.)
