The PWM Arctic F-series are perhaps the best of the budget quiet fans, in many tests being more efficient (that is, more airflow when adjusted for the same noise) than far more expensive fans. Unlike the old Panaflos, they seem to be consistently quiet and it's rare to get a bad (noisy) one. Truly a great deal for 5 or 6 bucks.
However until a few years ago, they specified a lifespan of only 30,000 hours--exactly the same as a sleeve bearing fan. FDB is just a sleeve bearing sealed in an oil bath, often with grooves intended to pump the oil around, and so the lifespan is primarily dependent on the quality of the seals. They no longer list a lifespan in their technical specs, likely because it's too embarrassingly low. But it is just as long as those expensive Scythe sleeve fans (though you can oil a plain sleeve bearing).
For comparison, the >$20 Be Quiet! fans are even more efficient and are rated 10x as long: 300,000 hours (34 years!).
Noctua fans are supposed to have less clicking noises than other PWM fans when set to very low RPMs, and are rated >150,000 hours.
Plain old ball-bearing fans last ~60,000 hours but do get noisier/rattlier over time. They are far less likely to silently stop than sleeve or FDB fans because when they start to go, the squealing will warn you!
The sleeve bearings in your car engine can last a long time because they float on a pressurized film of oil, and despite seeing more load and revs will generally last much longer than the roller or ball bearings in the wheels which are only greased. When wheel bearings fail, they squeal or rumble too.
