First determine which way your fan blows. You want to ulitmately place the fan on top of your Vid Card to suck up air, so it blows up ^.

Next, Hot Glue the 4 Washers in each corner of the 'bottom' of the fan.
Place it on top of your card.
Connect to 12 VDC power, and you're set

 Took me longer to locate my washers than it did for anything else. Who knows if it works? heh. Now I have 12 fans in there, though, at least until the water supplies come next week.

  After testing , my Motherboard Monitor temps showed an increase in both sytem temp and CPU temp by a couple of degrees, so I took it out. The only thing I can think that may have caused an increase is the disruption of the airflow in this particular case. I don't think all cases are as flow particular, because according to the article I read, he got a benefit. Whatever, it's something to try, if it doesn't work, you're out about 5 cents of hot glue and 10 minutes of your life.
