I do not have experience with this specific computer, but it seems that all small form factor devices with fans (laptops, all in ones, xbox) seem to run louder than their desktop counterparts because they use faster, smaller fans which make much more noise.  You could/should use a temperature utility to check your temps, but if they are where they should be, there isn't really anything you can do.

My experience with a Dell 780 was to get into the bios and make changes in there that fixed those fans that seemed to be trying to take off. There is information here:

I turned off the hyper threading setting in the BIOS and it really stopped the loud screaming of the CPU fan.

if you turn off hypterthreading, it will in essence, bottleneck your CPU causing it to not run at full force-which would cause it to run cooler, hence quieter fans. Small form factor computers often make more noise then a customary desktop-but a faulty fan can cause lots of nose to. You can often quiet them up by purchases quieter fans-but your only going to get so quiet, the smaller the fan the faster it will spin. just how it works.

its in the BIOS. Just be warned your PC will slow down. If you don't use it for anything except email and web browsing you probably wont notice-you use it for anything CPU intensive and you will notice

My apologies, I jumped on that too quickly. The Dell 780 I have has quite an extensive bios, compared to others I have seen. Having said that, I was reviewing the bios settings I currently have that is allowing the fan to run quieter, compared to how it was when I first switched on the tower, the fan was so loud it was like it wanted to take flight.

I will try replicating the bios as it was and post what I changed. I will post those results later.
