Thermaltake Volcano 11 is unbearable

Can anyone offer either a suitable replacement heatsink and fan setup or a mod to quiet my Thermaltake Xaser Volcano 11 cooling setup? I thought I could take the noise but it has gotten to the point where it's all I notice. My machine runs at about 49 degrees Celcius when under normal load and I'm comfortable at that temp but I would like it to be quieter and/or cooler. Any help would be greatly appreciated.

Vantec Aeroflow keeps my system at 36c under load running an AMD XP 2700+ Tbred, you can get one from <A HREF="http://search.store.yahoo.com/cgi-bin/nsearch?catalog=directron&query=Vantec+Aeroflow&.autodone=http://www.directron.com/" target="_new">Here</A> For $23.99 + S&H, I used to run a Swiftech MCX462, jet waiting for takeoff cooler, never again!!!, the Aeroflow is about 1/3 the noise level and worth every penny.

hmmm....aeroflow.....Maybe I got a different one...
The Aeroflow I got have a TMD fan with a copper centered Heatsink
And that one was loud!! compare it to my good old volcano 7+
with the 'low' fan speed setting of course.

I had the Swiffy too. Geesh, what a racket. I put a cheap slower RPM fan on it and you couldn't hear it. It only jumped about 4 degrees too.
