Fans running loud/often in FX50?

I bought my FX50 a few months back and since I got it, it seems like the radiator fans both run often and more loudly than expected. I had the coolant replaced just in case and nothing changed. I’ve never seen any fluctuation in the temp gauge etc, but the fans just seem too loud for a luxury vehicle. They don’t sound faulty, just like a lot of air moving and seemingly on almost all the time.

Anyone else have a similar experience?
 
Could be a bad cooling fan module or coolant temp sensor. Both could potentially make the fans go off like that. Both are a cheap fix.

Is it throwing any codes at all?
 
Mine (FX50) seems to always make a lot of noise when the A/C is on, this is a big change from my FX45 in which the engine fan made almost no noise. When I first got it I thought that a fan module may bad, but they change speed from pretty fast/loud to really fast/loud. They go off if I turn the A/C off.
 
Mine is a 2014 5.0 and it’s pretty loud when the AC is on as well. Not sure I want to mess with it though.
 
I had this issue with fans running constantly. It was a cooling fan module that wasnt replaceble so the whole fan assembly had to be replaced. I have the paperwork somewhere. Im out if the U.S. right now so i cant send a picture.

Hi OP, did you end up having to replace the fan assembly? Mine is making the same noise now too. Def not the AC noise that other posters mentioned.
