"MTBF 300,000 Hrs" I know they're ceramic bearings, but damn that's a long life. At their price, airflow, and noise it's a pretty good fan if the readings are correct. for $1.50 more you can go blue led.

 

wow, how long is 300,000 hours, is it like 30 years lol?

 

A bit over 34 years!
They're pretty good , i like the red!
