Loud “fan sound” when accelerating

Before anyone jumps to “that’s just your cold air intake” I can guarantee that it’s not.. my truck is bone stock. So I bought my truck almost 3 years ago and since I bought it there’s always been this intake kind of sound when accelerating it’s even kinda almost like a fan sound/loud sucking sound. I thought it was normal because I had the sport package (yes that’s dumb I’m new to dodge, the sound is always there unless I’m on the interstate doing 75-85 then the sound slowly disappears and the truck sounds like a normal truck afterwards for a couple days… then it’s back. Has anyone had an issue like this before and how do I fix it?
