DR3 - Are you thinking about watercooling the SB? Granted it gets a bit toasty but there might not be much of a benefit to watercooling it, especially given the complexity and flow restrictions of adding a block down there. Given that you don't have much clearance down around the SB you might want to consider a great block (I've tried it myself and was very impressed with it. Enzotech makes a few waterblocks and also makes some great heatsink & fan combos. I would highly recommend THIS heatsink & fan combo for your SB, its small, low profile, is quite, and cools very well even compared to larger and noisier units. Although the company is not well known (yet) their hardware is actually very decent and of a high quality as far as design and materials go I think. Below is a thumbnail picture of it on my old Blitz Extreme along with a whole bunch of other Enzotech blocks (both waterblocks and heatsinks). Let me know what you think.



As you can see from the picture, I removed the little screw tabs on the SB block because I used some thermal adhesive to mount it (instead of using the hardware as the holes didnt' line up).
