Fans won't spin up to check airflow direction

I have purchased the Coolermaster V6GT and fitted it to an i7 930 on the Gigabyte GA-X58-UD3R Motherboard in a Coolermaster HAF912 with Corsair TX650W PSU. I had to remove the fans on the CPU Cooler to fit it and I then tried a power on to check the fans i took off the V6GT cooler were refitted correctly on a push/pull configuration. The problem is that when I power up the fans dont spin up on the cpu cooler but the case fans do so I can't check, could this be caused by having no Memory and no Video Card installed?

 

You can test the fan with your power supply or a battery, does your power supply work ?

 

I managed to get power to the fans by removing the additional 8pin power to the board
