I discovered a large portion of the noise coming from my system was the solid mounted rear fan in the P180. So I thought I'd really slaughter the noise by soft mounting a yate loon in that spot. I had some foam collected from hard drive shipments at work, and piles of zip ties at my disposal.

I used a box cutter to cut the foam to desireable sized bits. Then a tiny allen wrench punched perfect perforations through the pieces. You can see in the detail photos exactly how I used the zip ties to hold it all together. One of the pics shows a zip tie "assembly" seperately so you can see exactly what I did.
I also removed the top fan. The change overall has resulted in a very noticable noise decrease, and idle temps are up about 2 degrees C. CPU 36c, MB 36c, chipset 32c (unchanged). Also I'm currently not running the cpu at 2750 as my signature says, 2500 for now to see how things go.
