Msi Z97 gaming 5, CPU fan strange behavior?

Hello, I just assembled a computer with MSI z97 gaming 5 and 4790K. Upon powering it on, I noticed that the CPU fan doesn't start spinning properly, instead it has this pattern:

Tries to start spinning (doesn't actually spin, just attempts to) > Stops completely > Tries spinning again > Stops completely > Start spinning

 

I never witnessed such behavior from any computer I built in the past for my self. Is this normal with this board?
I also would like to mention that 2 of the CPU socket pins are slightly bent but everything works normally.

 

Things I have tried so far:
Down-dated/Updated BIOS
Changed CPU Fan Header Connector

 

 

EDIT: I found a video on youtube that showcases what I am experiencing

I would think its more your fan that is bad. If you plug a different fan into that header, does it exhibit the same behavior?

I do not have another fan available to test with...

Then try plugging the same fan into a different header meant for case fans...

Nothing to see here ;)

I mentioned on the OP that I've already tried this, the out come was that the fan didn't spin at all.

Yea, that seemed like the likely cause. Glad you were able to locate a 2nd fan to test with!
