Why not get an exhuast pci fan? No room in the case? I't might be a bit old school but about 6 years ago so, I have just a heat sink card and I got something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16835888602 It dropped my card down good 15c+. Make sure to exhaust the air not blow. 90+ heat blow everywhere else is not good lol
