Hi guys,

thanks for all the replies to my previous thread about the 2" fan. I did
find a 60 mm fan made by SilenX in California that looks like it is going to
do the job for me. It has a noise level of 16 dBA as compared to the
average 50 mm fan with a 30 dBA noise level. My only problem is going to be
fitting it in the case. I don't think it will fit (it is too thick), so I'm
looking to install it outside the case, still allowing it to draw air out of
the case. I might need to make the fan hole bigger and don't quite know
what to use to cut it larger. Also am afraid of fragments getting into the
case and shorting things out.

Any suggestions on that?

How about a metal nibbling tool? Also available from Digi-Key.

A sheet metal punch will make a nice accurate round hole, though. But it
is awfully expensive if you're only going to use it once.

Use a nibbling tool. They're inexpensive. A bit rough, but it'll work.
You do have to be careful of chips and fragments. The best thing to do
is pull the computer apart so you have just the bare care, then clean
it thoroughly before re-assembling. It'll add another hour to the job,
but at least it will be a planned stripdown rather than having to
replace what fries when a chip that you didn't find works its way into
the wrong place during a session three months later.

It's not going into a computer, it is replaceing the fan in my new MOTU
HD192 which is exceedingly noisy in a control room that I've spent thousands
of dollars isolating walls, windows, adding acoustic treatment, etc.

I don't know that I can take it all apart, but that is a possibility. Okay,
now I need to find this nibbling tool.

Sorry, I forgot, but sinc you're going to have to open it up to
replace the fan anyway, do a little exploratory surgery and see if
it's reasonable to strip the case, do your cutting, and put it back
together again.

I really wouldn't do it any other way.

On the other hand, you might find that the new fan blows enough air
through the existing hole and you could just mount it to the outside
of the case with double-faced foam backed tape or hot melt glue. It
might fall off in a couple of years but that's easy to fix. And you
can always put the original fan back when you want to sell it (which
I'm sure you will, eventually).

Worst advice yet. This will assure getting metal dust inside the cabinet.

I honestly don't know how to disassemble a MOTU, but I assume it is
mostly a circuit board with surface mounted connectors and ribbons to
the chassis leds and jacks. Maybe it's more integrated with the chassis
than that.

Masking tape, anti-static plastic bags, dremel tool.

Although I still think I'd personally just remove the fan, and add a
heat sink in its place, if I was going to modify a $700 piece of
equipment in the first place.

I'd much rather make precision cuts than the ugly job that a nibbling
tool guarantees, that's for sure. I never noticed any fan on my
friend's 828. I guess I subconsciously eschew motu; don't like
unicorns. I have a layla-20, and I must say that thing gets too hot to
touch. I can see how it would be tempting to spec a fan for it, but is
it essential? I'd really try to figure that out with measuring tools
before I got out the cutting tools!

If you're not to bent on the SilenX fans... I'd recommend Papst fans.
12 db. Moves a lot air too. I like use them on acoustical PC/Hardware
boxes. Like them the best. You can get them at like some quiet PC
online stores. Google it.
