"And, really, how often do modern fans fail ?"

Few companies give MTBF figures, but those that do rarely say more then 40-50k hours, which is about 4-ish years. At at the MTBF (if correctly given and a constant rate) only 37% are working by then.

For always-on devices they are *significantly* more likely to fail than semiconductors.
