Yeah I threw it on the fan just so I wouldn't lose them in my room AGAIN (lost them like 4 times during multiple runs to radio shack and drinking)! The fan itself pushes them in that order but if I separate them they align perfectly on the outside but lose their strength. So I need to open up a few more hard drives here at work to stack them. Was just wondering if the hard drive magnets would be enough on the 120mm fan or should I just purchase some stronger ones?
I use 1 hard drive magnet on my 120mm fan and it works great.
