From now on, Coolers WITHOUT Fans and WITHOUT Noise!!! :grin:

Santa Clara (CA) - Sun Microsystems has been issued a patent for a heatsink design using magneto-hydrodynamic technology in a closed fluid system. Such a system migrates heat around via the internal liquid, but without mechanical pumping action. This makes it very quiet and potentially very power and thermally efficient.

Just like the drive system used on the Russian submarine Red October in the movie "The Hunt for Red October," this type of magneto-hydrodynamic, or "caterpillar," is designed to use micro-magnetic fields to squeeze internal bladders which in turn create a pumping action. While the end result is a real movement of liquid there are no moving parts to this design. The bladder is squeezed remotely by magnetic fields and is, therefore, almost completely silent.

In-case ambient temperatures are still the issue, you still need a fan across the thing, and airflow = noise.

Yep, I guess you're right ;-). But still, you must admit it's a very interesting and cool (:grin:) invention :? Don't you think? :roll:

I havent read the article.
But I think its for servers.

Soon as I read the title I was thinking of that movie... :lol:

Very interesting concept, but as the article said it seems to only have real value for tight server concepts, such as blades where a intricate network of lines could be routed. For the desktop system it would be no different than a heatpipe based cooler, give or take a little on the performance.

Yeah...I think that it'll be much more efficient in Servers. :roll:

I'm staying with my Heat-Pipe CoolerMaster Hyper 6+, which I'm VERY satisfied with...;-)

Very interesting read. It must perform rather well if Sun patented it. Nobody likes to patent garbage.

Very interesting read.
Thanks! :icon_tiphat: I'm glad you liked it...:grin:

Yeah, usually that's true, but not always...Let's hope it won't be for "nothing"...:???: ;-)
