A good datapoint, thanks.

If by "single slot" you mean "doesn't block the adjacent slot" you may 
have problems. Most (make that every) fanless VDPAU card I have seen 
will block the adjacent slot to some degree.

I have an  EVGA 8400GS card with a fan that can barely be heard (just 
put it into service last night in fact), I have also seen some 
replacement GPU fans on the market that might be quieter than some 
standard ones.
