Plumbing/Noise Question

[Reef23]

Hi all,
I will be plumbing my new tank in the next few weeks and had a few questions on noise. My tank has a coast 2 coast overflow with three drains and 2 returns. My sump is located behind the wall that the tank sits against. The drains will be coming out the bottom of the overflow for about 10 inches then a 90 fitting and a 12 inch horizontal run to another 90 and straight down into the skimmer section of the sump. Will this cause any noise plumbed this way ? Any suggestions
