Hi this is my first post =')

I was searching for this topic on google and found this thread, I hope its ok to raise this thread after so long. Reason I post is because I would like to figure out if it is at all possible to reverse the direction of airflow through a PC fan. I have 2 power supply fans I have recovered from junk computers, and I would like to experiment with counter rotating fans. My idea is similar to the way a jet turbine works, having 2 fans counter rotating but the direction of airflow being the same.
To my disapoiment I have realized that simply reversing the polarity on the fans will not work. So I hope someone can give me a hint as to what might work. Thanks for taking the time to read.
