Wiring 12 volt fans - series or parallel?

[Zzippper]

I am building a DIY cooling unit for my tank...  2 x 250 w MHs are warming things up a little too much.

I have two 12 volt fans and a 12 v power supply. Should I wire the fans in series or in parallel?
I'm pretty sure it's supposed to be parallel... Can anyone confirm? Thanks!

all - to the neg wire, all + to the + wire. not sure what that is called. if you ran it +- then +- you would need 24volt supply i believe

This is called parallel wiring.

+- then +- .

This is a serial connection.

Thanks for the confirmation.
