Sorry, should've provided some info.
Intel® Server Chassis P4000M Family
The chassis I'm looking at specifically is P4308XXMHJC which is part of the P4000M family (I think, it's not explicitly stated).
This particular chassis has 2 1.2kw platinum psu's and hot swappable fans.
Per the P4000M manual that means 5x80mm fans.
Considering the chassis was designed to possibly vent 1.2kw worth of consumption, I'm not sure if the 80mm fan wall or psu's are screamers.
I found a video of a guy with a 750w PSU's and 2x120mm fans version of this chassis and it screams on power-on like most servers, but does get to much reduced levels after POST.
tl;dr - 1.2kw psus and 5x80mm fan wall, recipe for loudness?
