Are both power supplies working/plugged in?  The fans will run on high if only one power supply is on.

It's a 1u server.  It's not designed to be quiet.  If the fans run slower, it will overheat.
You have the wrong equipment for the environment.  Or vice versa.
It's like a 7-foot man in a Chevette.  You can't modify either one sufficiently (on a budget).

Not cheap.

See http://www.xrackpro.com/
Pricing here: http://www.xrackpro.com/HP-Server-Rack-s/25.htm

4u = $ 600
6u = $ 800
12u = $2,000
25u = $2,500

Thanks for your comments....

we have two of these servers in a rack and due to re shuffling of office space. I am being locked in a closet  well 15ft by 15ft office with these things .

We have no real budget to buy a new rack cabinet (maybe in the near future)

Can you not get different fans for these things?

How about insulating the cabinet with this?   http://www.acoustiproducts.com/en/acoustipack.asp 

Both Power supplies are plugged in.... for your info....

Cheers

The noise is coming from the fans, which ventilate through holes in the chassis, then venting through holes in the rack/cabinet.

Do you have an existing cabinet?  You said:

>so it can be installed in a working office

Typical cabinets are ventilated on multiple sides.  Sound reducing cabinets are purpose-built with sealed/insulated sides and baffled ventilation.

You can't take a cabinet that's full of holes and cover it with acoustical barrier or insulation.  Your equipment will overheat.

Your best option is to baffle the sound.  For every 90-degree turn, the apparent sound is reduced by 1/2.  I've seen loud workstations and switches placed underneath counters with cabinets placed in front. Leave plenty of space on all sides for air to circulate.  It will still get warm (over 90F), which may decrease the lifespan of the equipment.  You can try putting eggshell style acoustical foam on the hard surfaces to reduce noise reflection.

Taking the equipment below desk level will cut a lot of the noise.  No straight shot to your ears.  No straight shot to reflect off the walls.

Hope this is helping.  Not a great situation to be in.

Quieter fans will move less air unless they are much larger in diameter.
You would have to cut holes in the case and the holes would need to be unobstructed.

The best cheap quick fix I can think of is to put it behind a shelf unit, a desk, or an office partition.
