I was about to suggest this. If the only problem with the card is the fan, then just convert it to water cooling. It will be much cooler and quieter than you'll ever achieve even with a non-faulty fan. I would say the expense can be justified based on the free upgrade you received. Alternatively you can buy replacement fans on Ebay usually.
