Can you wire computer fans in series?
Fans require a minimum start-up voltage or the fan blades won't start rotating. If you wire two fans in series you will cut the voltage that each fan receives in half. If that voltage happens to be less than the start-up voltage then non-functioning fans don't help you at all.
What happens if you put two fans in series?
Using Multiple Fans "n" fans in series will increase pressure "n" times at a given flow rate, with no additional free delivery flow. Fans in series can be useful in high resistance systems. "n" fans in parallel will increase flow "n" times at a given pressure level, with no additional shutoff pressure generated.
Should fans be wired in series or parallel?
Use 12V and wire the fans in parallel. If you use a 36V power supply and wire the fans in series, the voltage might not be shared equally. This could even cause the fans to burn out. In parallel, they will all get 12V.
