You can pick up a 265cfm can fan from ebay. Search for air booster fans or duct fan. As far as building a cooltube, you can get the fan for 30(ebay), a candle vase for 9(michaels, ac moore, basically a good craft store, just check the candle section). Add some ducting and supplies from home depot or lowes or any hardware store, for around 30 bucks and voila you have everything you need to make a nice cooltube that will dramatically lower the temps and can help save you some money. Hope this helps- Diz:rasta:
