Which year did BMW stopped using Fan Clutch?

Is there any gurus here that know which year did BMW stopped using Fan Clutch?
Maybe around 2010 models and later, just a guess?

Browsing realoem, it appears that the E39 was the last one with a mechanical fan.

Arrow N series engine have no mechanical radiator fan/water pumps....

Starting with the "N" series engines... BMW went to an ELECTRIC powered water pump AND thermostat. So that is basically around 2008 model year or so. One exception would be the e60 535i (twin turbo six N54 engine code) which was the first 5er to have no mechanical water pump or mechanical clutch for the fan. The N54 engine was one of the first BMW engines to embrace electrical water pump and thermostat.

First car to get the N54 was the 335i(e90) in 2007. Then the e60 and later the e82(135i's) and all the rest of BMW lineup: X's, Z4, etc.

a electric fan as a SECONDARY fan(aditional to the mechanical clutch coupled fan). But all e46's(and e60's, except for the 535i N54 USA only model) had the old mechanical clutch driven fan off of the (mechanical) water pump. All M-series engines had this setup.

It was not until BMW came out with the N-series engines that we started to see NO mechanical clutch driven fans.

ALL M-series engines had a mechanical clutch/fan & water pump.

Don't you remember how everyone with an e36 or e46 would do a delete fan clutch and add on an electric fan. This free'd up a bunch of (free) Hp with no real loss of engine reliability.

Not exactly. My 2005 530i has an M54 engine with mechanical water pump but electric fan. All factory. If I'm not mistaken, the 2004 had the same setup.

Again, my 2004 M54-powered 330i only has an electric fan from the factory.

Guys, the E46 used both setups. Autos had the mechanical clutch while manuals had electric. It's a no brainer to get a 6 speed E46!
