Hello, I have several R715's and R515's all AMD servers. They run great and the noise level is minimum.
We recently purchased our first Intel servers, two R720xd's. We went with this model only because of the chassis configuration allowing many more hard drives.
The units are working but extremely noisy. When our other servers first turn on, the fans make a really loud noise like a jet is taking off. Well the R720xd sounds like that ALL THE TIME. Is this the normal noise level for this server? We have a closed server room with metal door and it can still be heard from outside the room. Had I known this model was so noisy, I wouldn't of purchased it. Dell needs to start publishing noise levels if not already.
