why pay extra for dual ball bearing fans? Because if the hot end fan shits its self mid-print it can lead to horrible things like major clogging of the hot end and ruin a long print. These fans do cost a little more but will last a lot longer than sleeve type fans and make less noise at high speeds. Dual ball bearing fans also fail very gradually rather than die a sudden death like a sleeve bearing. This slow death makes the inevitable failure much more predictable allowing you plenty of time to replace them before things go pearshaped.
Dual ball bearing fans offer;
- quiet operation
- reliability
- long lifespan
- ability to position in any orientation
- slow predictable failure rather than sudden death
- excellent cooling properties
