hi guys, i'm looking for a pci slot fan that blows the air out of the case like : http://www.amazon.com/Rosewill-RFX-100-90mm-Case-Fan/dp/B00552Q7SC/ref=pd_sim_e_10 or http://www.amazon.com/Antec-Cyclone-Blower-Expansion-Cooling/dp/B000051299/ref=pd_sim_pc_3 but like 2 fans or something more powerful.. i don't want those that just blow the air below my case want those that blow it outside the case.
