Re: Re: Quietening server

[Simon Ryley <simon.ryley@xxxxxxxxxx>]

Sorry, didn't explain very clearly.  The PSU I have is an Antec one that
is fitted as standard into the Aria case I bought.  This case may not be
suitable for you as it is only for MicroATX motherboards, with a maximum
of three hard drives and one optical.

You can however get similar PSUs for normal server tower cases.
www.silentpcreview.com lists the best.   I have heard good reviews of
the Seasonic S12, which uses a large 120mm fan.
http://www.quietpc.com/uk/psu.php
has uk prices for quiet PSUs.

I can only compare the noise of the two PSUs in their cases as I didn't
put the quiet antec PSU in the old case.  I did run both machines
without their side panels at various times, so I the added quietening
effect of the side panels of the Antec case can be ignored.  The Antec
PSU was much quieter, very little fan noise in comparison to the old
machine, especially as the fan is big and spins slowly when its on, and
is off some of the time.  The old machine PSU had a constant speed fan
that blasted away even when the machine was idling.

I would rate the effect of changing the components in the following order.

1) PSU (biggest reduction in noise)
2) CPU fan (got rid of an annoying background whine, the replacement
Zalman fan is super quiet)
3) HDD. (Can now not even hear it working, the old one was very loud,
especially when defragging)
4) Case (Didn't chop noise much, but does dampen the noise of the DVD
drive when the side panels are on)

Hope that helps,

Simon
