I have quite noisy HDs, and if i'm to change it will be 15000rpm ultra-320. These drive *require* cooling even under normal conditions. And guess what they're far from silent.
Now sealing them with foam to prevent noise would just be asking for problems. Hence some kind of cold device designed to take the heat away from the surface of the heat spreader of the HD. And why not a WB ??
Now this WB hasn't to be as wide as the HD itself. Someone tried with a standard CPU block and it was allright. The main problem is mounting. With a HD-shaped block you can use other HDD screws or standard case screw holes.
A HDD has an operating temperature range, and usually it's better for its mechanics to stay cold - unless you've got some kind of gas powered HDD 
NOT freezing cold, just room temp.

Why NOT use fans??? You still should have air flow through the case. Use a couple SILENT slow 20-25CFM 80's and you cannot hear them period. How quite do you really need it? A fridge makes more noise than most computers I have? hardly a problem and they are all in my sleeping room. You really need air flow on a lot of newer mobo's, my 8K7A's has 4 little heatsinks right below the CPU that MUST have some airflow or the comp locks up when overclocking, the DDR need some flow as well. Use slow speed fans and you will get enough flow and you cannot hear it. If you are running stock then you don't even need water cooling at all for a silent effect. I am not sure why people complain about hard drive noise as it pretty quite and hardly noticable. Typing on the keyboard makes more noise than both of my OC'd air cooled comp's and my water cooled one combined. Of course I am a construction worker and noise is a part of life.
Very cool work on the block though!!! I like it, I really like that you got more practical use of it with 2 drives!!! That makes it almost usefull. Nice setup non the less, and creative work with the tools. You could do some cool stuff if you had a Mill.
