Just cleaning out my closet, found these in a corner box haha.

Have done multiple custom PC builds in the past and these are from one of them. 

Should be functional, I've never had dysfunctional fans that I can recall. But, I did not test them so I'm just selling AS IS for convenience. 

If buying the entire quantity (5), I'd be willing to do like 5 for 15. Again, convenience. Just trying to clean up.
