PSU continuously beeping

wrote:

my PSU was fairly loud. Since I wanted to have a more quiet
solution and didn't want to spend money on new PSU, I bought
2 silent fans (one 18db and the other 17db)

Wouldn't silent fans be rated 0 dB?

with equivalent airflow to the one I had before. I opened up the
PSU (Antec TruePower 330W) and replaced both fans. Now
I get continuous beeps comming from the inside of the PSU. It's not
like the PC speaker would beep, that's not it at all. It's just coming
from inside of the PSU. The beeps are continuous, folowing one another
in aproximately 1s intervals,

If I'm working on something that requires some disque* activity, the
beeping stops and returns when disque* activity ceases.

I put back the original fans, wired them correctly, but the noise is still there.

I don't know why, I thought the sound was coming from the PSU. It
sounded just like it was comming from there and since this was the only
thing that changed in my computer, I thought it was it.

But now I started listening to other devices in my computer. I
determined that it is the Maxtor 160GB disc that is making the noise.
How wrong is that - will the disc in the near future fail me?

Is it making the case vibrate? I've had cases resonate at slowly as
every two seconds.

First, any time you suspect PSU fan noise, _temporarily_ stop them by
sticking plastic straws through their blades, preferrably before
turning them on. Straws are good because they flex enough to prevent
damage to the blades. You absolutely must not use anything that can
conduct electricity, not even a pencil (the lead conducts), because
there's lots of exposed high voltage right next to most fans, often
even on one of the big heatsinks (I measured 170V DC on one in an Antec
SmartPower).

I accidently tore out one if the fan's wire - the yellow one.

In case that ever happens again, never leave wires dangling in a PSU
because they can easily come in contact with high voltage. Either cut
them really short, or cover each end with heatshrink tubing (not
electrical tape -- comes unravelled).

Buy earplugs

You are the only person I have come across who could make the PSU or
the hard drive beep.

I would buy a quiet PSU made by Akasa, Arctic Cooling, Cooler Master,
or Glacialtech.

Depending on if you are using an Intel or AMD processor, you can buy
one from as little as £15 for the Socket775 Artic Cooling Freezer 7 to
only £9 for the Socket 754/939 Glacialtech Igloo 7200 Light.
