I want to hook up both fans to the same power supply. I also have a converter that is 5V, 2000mA. Is it safe/ better to use either one? Thanks alot.

You can run both those fans on that one converter
2 12V 180mA fans equals 12V .360 mA
Your converter is 12v 1000mA which is 1 amp
The 5v 2000mA converter may or may not run the fan, but the fan will turn at a slower speed.
Remember this most PC fans utilize a 3 wire connection Negative (Black) 12 volt (red) and 5volt Yellow.
The Yellow wire is for speed control.
So even when you hook these fans up they never run at full speed and are not designed to run at full speed constantly. Only long enough to cool down the PC Case.
Examine how big your grow area and that will determine how much CFM (Cubic Feet per minute) you need
