Video Card Fan Not Working...please help!

Hello,
I recently put together a brand new computer, however BOTH of the video cards I installed have non-working fans. I also got the "no signal" error so I tested everything on the comp and even got a new motherboard when I realized I have a bad processor, which I am getting replaced.

My question is this.....will a defective processor cause video card fans to malfunction as well??????
