This model uses a new air duct but the core air cooler is still the standard Dell OEM lga1151 socket cooler.  Bios is designed to specifically detect fan resistance load and current drawn.  When a replacement fan has significantly different resistance from stock fan, you get a startup error.  Consider checking out other Dell OEM lga1151 heatsink fan. Perhaps one of those is quieter than yours now.
The CPU fan of my Dell Inspiron 3671 is not as quiet as I like it to be so I purchased a 4 pin 80 mm Noctua Redux to replace it. The fan runs with a variable speed but my PC says : Processor Fan failed to respond correctly. Did any of you succeed in replacing the CPU Fan with another aftermarket one? If yes, which one will work? Many thanks
