The fan is always spinning, so more than likely if you really listened with minimal road noise, no chatty passengers, and no radio playing you'd still hear it. When it's not fully engaged it just won't match engine rpms, but rest assured it's still moving air.Another update. Just drove home and it was on at some capacity from low tones (hard to hear but definitely present). Less than a handful of times I did notice not hearing it. It’s only 78*F here in Phoenix currently. . Current temps: coolant:192 , trans temp: between 165-170, oil temp 199-201, oil pressure:32PSI
Im beginning to hate this fan/fan clutch design in its entirety lol there’s no upgrade I’ve seen with proof and data behind it other than the mishimoto system that but that’ll run me a few grand
If you're not seeing abnormally low coolant temps (I hovered around the 168-180 degree mark in the summer) the fan is disengaging. Possibly not as it should and when it should but the clutch is still hanging in there for now. Have a shop test it if needed, or just ignore it unless it fails.
You might slightly be able to hear the fan all the time, but it should require you to really listen for it (unless it's fully engaged). A lot of manufacturers use the same design. GMs and Fords aren't really much different and I heard my fan as often in my F250 as I do my Rams. Heck, we hear it in our Armada as well.
Are you expecting not to hear any fan noise at all? Certain noises irritate me as well, so I am wondering if your expectation is that you will hear no fan noise at all. Probably not a reality and you might possibly be more keen to listening for it since your brain has marked it as a nuisance.
I missed this earlier but you mentioned that the fan seemed to kick off when you turned off the AC. The fan does run more when the AC is on. It's part of the heat exchange process. It's pulling air across the condenser that's in front of the radiator.
