Hi, @Aiden_Shabka, and welcome to the community! I’m sorry it has taken this long for you to get a response. There could be more than a few reasons you have noise in your render. I’m on mobile, so I’m not able to look at your file right now, but before I do, I thought I’d link you to the manual page about reducing noise: https://docs.blender.org/manual/en/latest/render/cycles/optimizations/reducing_noise.html#reducing-noise
In the meantime, what you could do to test your volumetric scatter hypothesis would be to disable it and see if your render time improves.
When I get a chance to look at your file, I’ll see if I can come up with any other suggestions!
