Do you hear a fan blowing to cool the radio?
Hi Everyone,
We have a 2014 X3 28i. We recently noticed that there is a quiet but rather bothersome fan blowing on behind the radio controls. I can hear it blowing through the vents, after the climate control is off. It almost always turns on after driving for 10+ minutes. I don't recall this fan noise in the past, typically car the car is dead silent when you turn off the heating vents. Brought it to the dealer and they said this fan is very normal and that its a "newer feature." They did not do anything to correct the "issue". Even when the car is shutoff the interior fan continues to blow until it's locked and about 30-60 seconds pass. I am aware that other mechanical fans may make noise after the car is shutoff; however, this is a specific interior fan behind the climate control area that blows on the inside of the radio (as the dealer claims). Has anyone else noticed this as well or is this an actual issue with our X3? Also note, the fan pushes out no air from the vents, it rather circulates air behind the controls. I've been reading posts here for a while and appreciated everyone guidance. This is my first post, we picked up our '14 X3 in October and have enjoyed it thus far. The temperature in our area has rarely been above 35 degrees, so we are no experiencing any heat that would be out of the ordinary. Thanks |

Interesting that you mention this, but I hear a noise from behind the radio/idrive screen. It does sound like a fan. I can't hear it above the stereo, but if I have the music off, it is a bit irritating. I am going to mention it to the dealer when the car next goes in!

Thanks a lot, I really appreciate the insight. I'd be curious of any other members have noticed this before and if I'm just driving myself crazy with this small issue.

You basically have a custom built desktop computer stuck in the dash there. It packs a fairly powerful CPU, hard disk drive, and a current generation graphics chip. Stuff like that is gonna generate heat, it's a fact of life. To cool a hot computer, you will need a fan. I hear mine whenever the NBT boots up when opening the door, but I quickly ignore it once the engine, ventilation, and radio are going. Don't sweat it. Turn on the radio and enjoy the drive!

Yep.. I have the 2011 x3 20d with basic iDrive, 7" screen, no nav, no hdd.. the fan noise is there. I only notice them when the engine is off (after shutting off the car, or when turning on the car without starting it), otherwise not noticeable at all.

I had an old car once with a mechanical cable driven speedo and the cable drive made a similar noise to this. If you have had one, you may know what I mean. |

Have you brought it back to the dealer?
I have a 2016 320D. Exactly the same issue. Incidentally, this annoying fan sound also gets activated, when a door or doors, trunk or hood are opened or simply turning the radio on. Then when driven, it becomes progressively louder as it coincides with engine revolutions. The sound actually drowns out the a/c blower. I sometimes get confused as to which fan is running. On the bright side, it shuts off in exactly 5 mins. and 55 seconds. The timer begins as soon as the engine is turned off. The doors, trunk and hood are closed. Unfortunately, turns right back on as soon a door is opened, or an accessory is turned on like the radio. This is super annoying. Can this fan be permanently disconnected?

I assumed you were not aware it's a 7 year old thread, that's why I mentioned it, sorry, my bad. Maybe someone else will jump in and help you |

No problem! The dust usually throws the fan off balance, I’ve seen this a lot on the e38/39 hvac fan. If possible use compressed air to clean but be very gentle.

Am glad that this is not an isolated incident. The dealer wants the entire head unit replaced. Thanks again.
