Summary: Now, for my personal tech tip. This fan recently slowed down and started making noise. I started researching buying a new fan and became curious about how these fans worked. Basically, sleeve bearing fans will stop working once the grease is gone/dirty in the sleeve bearing You can also tell this by spinning the fan blade manually; if it does not spin freely, it is likely a grease issue.
Pros: This is a recently priced fan that has lasted me several years with the PC running continuously. The LED lights are just right.
Cons: It will stop working at some point, as do most PC fans.
