I would suggest, depending on card, an Arctic-Cooling heatsink/fan for your video card. I believe Revision 3 will fit a 9800SE. You can purchase it on ebay for about 16.99$ and it functions more efficiently than the two you linked. Instead of dissipating heat off the card into the case it dissipates the heat off the card outside the case.
Arctic Cooling's VGA Silencer Revision 3
*Not too expensive
*Direct heat exhaust
*Cools better than stock by 30 deg C (straight from arctic-cooling.com)
*Quieter than the stock fan on low speed and about the same on high
*Takes up the PCI slot directly under the card.
*Not much else i can think of
PS I just ordered the ATI Silencer 3 (not to be confused with Rev. 3) for my 9800XT, should arrive tomorrow. I'll let you know how the install/real world results are on it.
