It's been a while, but I think so. May be worth waiting for other people's comments first though.

Stop and think a second, something is more than nothing.

It will work, but you wont be able to control your fan speed. It will run at 100% all the time as there is no way to control the voltage.

it will run, at full speed all the time no matter you like it or not. Bad thing since this fan is rather loud.

Yep. If all you want is a spinning fan a 2-pin black/red wires to Molex adapter will get the job done. However is there a resistor built into the adapter? You say 7V but molex cables only have 5V & 12V rails.

Yes, that works fine and the fan should run at ~60% rpm.
