If you use a power lead from the power supply and split it to two fans do they receive less power?

If you wire them in parallel, they'll both still be at the same voltage. If they're in series, there'll be half the voltage drop across each.

Since you said split, I assume you mean parallel. In this case, they will both be pulling the same amount of power. It will just draw twice the current from the PS.

thanks for the reply

I have a case that came with 120mm panaflow's installed. Since they are 120mm I connect them to the power supply and not the motherboard. The fans came wired with a power lead and then another connector from that, so on the one line two are connected. Any ideas on whether this would be series or parallel

I'll make you a drawing:
My ascii art ain't the greatest, but it should get the point across
.'s are just spaceholders, ignore them

Series:
PS-----Fan-----Fan--
PS......................|
PS-----------------------

Parallel:
PS---------
PS...|....|
PS..fan..fan
PS...|....|
PS---------

That make sense to you?
