A  heat sink by itself won't work properly, in fact it might be worse.
The genius who decided to make the PCI cards face downward didn't
think that you can't get natural convection  that way in a tower case.
All my PCI cards seem to run hot.  

The 3Dfx fan works fine for me.  You'll be amazed at how simple it
looks but it works well and is foolproof. It is worth the $16 price
since it is easy to  buy and install.    (contact www.3Dfxcool.com)
Don't mess with glues as if they are improperly applied (air  gaps)
they can actually make the heat worse.  If you  got a spare fan lying
around  and are handy with tools you could probably rig up something
similar to the 3dfxcool. You can also consider a front fan, that seems
to blow a lot of air across the PCI cards. 

I have been running my  card at 60 for 3 months.  I leave it at this
speed all of the time and have had many long Wing Commander Prophecy
sessions without a single glitch.
