DeadHead,
I have the same hsf you have and had the same problem, it's a bit too loud. Yesterday my
TMD fan came in from SVC, and I installed it last night. One big problem with it, it does not fit on the Dr. Thermal properly, it's too big. The sides of the fan are curved and will not fit into the plastic cover of the cooler. I was going to just screw it on anyway, and seal the sides, but my screws weren't long enough so i used some of that super sticky 3M double sided tape, the kind used for applying molding on cars, and aluminum duct tape. I put the 3M stuff on the bottom of the fan and placed the fan on top of the cooler and pressed it firmly in place. Then I used the duct tape (the foil kind, not the grey cloth stuff) to wrap the sides to prevent airflow loss and also as a backup just in case the other tape didn't hold. Isn't the prettiest looking setup, but it works. Anyway that fan is almost dead silent and cools very well. It has a 33dB rating, but I can't hear it at all. I'm running a 1.4g T-bird on an Asus A7V and my idle temp is 42c, very good considering my mobo temp is at 35c.
I tried the 7v trick before on the same cooler, but the noise drop was minimal and the temp went up like 3c so i didn't think it was worth it.
I also replaced my crappy yates-loon PS fans with L1A's, and I now own a very quiet and cool AMD box...
