Ahh, so you have copious spare time to spend on this. :-)

Err ... high technical comprehension low reading comprehension ?

If you have room beside your video board, try using a bigger,
slower fan. Try using a bigger heat sink[1]. Try them together.
Those can accomplish the same cooling as your noisy fans.
Unfortunately, many video boards have another board beside
them so there is no more room for a bigger heat sink and
bigger fan.

As mentioned in my reply to Christian, I think I am first going to try the blanking plate fan mount (see that message for a link to someone who has already tried it) but, not having a pop-rivet tool I will revert to my motor tool box and get out the short, stubby screws and tube of Loktite red. Over torqued nuts + anaerobic sealant beats squished metal tubes and washers any day.

     E.g. http://colug.net/~jep/images/tywrapped-fan/

You should always clip those long tiewrap ends. Just like you should always wear clean underwear when you go out. Because you never know who is going to see.

Rubber mounts for fans will reduce case vibration.

... provided there is something at the other end the rubber mount can be glued or screwed into ...

Water cooling can allow to eliminate the noisy fans from
inside the computer. With a big enough exterior heat sink,
you will not need exterior fans either. A cooling tower
above the external radiator will silently help the air flow.

It also allows you to more closely control the cylinder head temp for higher compression and allowing the use of lower octane fuel while improving BMEP.

Avoid having things close to the leading edges of fan blades.

With all due respect, some of us have piloted rotary wing aircraft and have oodles of first-hand experience in this bit.

Things close to the leading edges make more noise than
things close to the trailing edges.

That's because the leading edge can more easily break the sound barrier. But, you knew that, right?

Use your imagination. _Try_ stuff.

[1] Bob Pease[2] would recommend using a cylinder head from an
     air-cooled motor[3].

Cool. I was wondering what else I could do with that spare radial finned alloy head from my 1959 Zundapp Super Sabre. I wonder if Komeri has coarse threaded DIN spec 14mm bolts for mounting it.
