Just when things are getting interesting on the cooling front. This is just a lull in the action

SFF I think is where it is headed.
why not use the aquired base of knowledge to jump to the next level.
How about a mini water cooling system? competition? I took apart one of those enhiem pumps recently man oh man cheap stuff. build your own pumps using quality parts. they make 90% eff. pancake dc motors instead of the 30% eff. they are using now. the impeller was poorly done I am sure that could be improved off the shelf.
Build your own heat pipes
Use a TEC to cool the top of the waterblock rather than the cpu(i do not know if it would work)
combine technologies- waterblock to TEC to Heat pipe to radiator.

whatever
Cool 100w in a case 1 inch high
Master airflow application- instead of putting 10 screaming fans on a case figure out how to do it with one.
Build your own radiators etc. A Case mod plus cooling Site?
Big opportunities in vid cards- never seen a more poorly excuted cooling solutions.
I think with cooling you have to take a more holistic approach rather than just water blocks or HSf. Total system soup to nuts
in a harsh enviro.
you can add test capability easily, Build a airflow measurment chamber for a few hundred dollars
Get a decent sound meter off of ebay
I think to improve the site you need to refine it. as noted earlier get your readers involved and expand the focus a bit but keep the basic premise intact.
best o'luck
