I bought an Antec Sonata case to try and quiet down my wife's computer in the Kitchen and found that the BIGGEST noise I had was not the power supply, but the fan on this OEM card. Any suggestions for a replacement CHEAP -- card was only $70. Or should I try a passive heat sink (and how/where do I get one)-- she does nothing but e-mail and web surfing so not very taxing on the card at all.
