Hi,
Read a recent cooler article, where they put one fan pushing air on the heat sink and one removing it from the heat sink. These fans presumeably attached to either end of a heatsink covered by a nacelle like looking plastic cover.
I encourage you to try this experiment with two identical
fans.
Tape a large garbage bag to the outside of the fan making sure no air leaks around the edges. Plug it in and time how long it takes to fill the bag. (use a paper cone made with some loose sheets of paper to hold the fan if they are small). Now join two fans together and do the same.
You will note that there is not a significant difference in filling up the bag with air (Perhaps 5 percent).
Conclusion: Two fans in series are not going to add alot of airflow over that provided by a single fan.
The loving are the daring!
