I just came up with the perfect solution. I used an old dual-fan Card Cooler I had and modified it a bit. I'm talking about the item sold that mounts 2 80mm fans blowing over the video card by mounting to 2 of the PCI/AGP/PCIe card screws.

For an idea what it looks like, check out http://www.thetechzone.com/reviews/c...ard_cooler.htm.

It's simply 2 metal brackets, one mounting the top of the fans and the other mounting the bottom.

I simply used one of the brackets and bent the mounting portion over at a 90 degree angle so I could mount it to the back of my case. Now, I have 2 80mm fans blowing over my DIMMs. My ThermalTake Tsunami case actually had a vacant screw hole in the perfect place already, but anyone could easily drill a small hole into the rear plate of the case.

The only issue I could see with this is if you have a VERY large heatsink on the CPU. That might position the fans either higher than the lower DIMM, or require you to position the fan bracket out farther.
