what does the heatsink of the p40 look like with the blower shroud removed? if it's just a normal fin stack i would just zip tie some 120mm fans to the front of the card after removing the shroud. the new 120x30mm (standard is 25-26mm thickness) antec fans (storm 120 t3) perform exceptionally well for the price and max out at 2200rpm, i would pick up a few of those. i have some of the 140mms and they're very very good.
