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.
