or run dual fans so they come on with a stepped speed, so they start slower and as long as the temp is good they run slower, coming on full rpm when needed. that would require some wiring though, possibly a couple of thermo switches with different temp settings and possibly a resistor or dc motor speed controller set for a slower fan speed. of course, air coming is is only gonna be as easy as air can get out somewhere. no place for easy air escape means the hot air is just gonna circulate under the hood.
