Looking for these? A vertical wind heat sink

For those who asked whether the fans within Jalapenos are blowing upwards or downwards, it's upwards in the original package. I have removed the casting and flipped the fan to blow downwards.
I agreed that BFL might have tested both way and decided that blowing upwards is the best way but this is with the constraints of the casting. So without the casting, i think it's better to blow downwards.
