Hey guys, I just saw this and was wondering if anybody tried it. Or if it might be one of the upcoming reviews...

I've seen these, but not used one. I'm a little confused about what the heatpipes are meant to do. Dont heatpipes transfer heat from a "hot" side to a "cooler" side? Aren't both sides of an HD more or less the same temp?

Anyway, you'd probably see some improvements in noise levels since it looks like it decouples the drive from the case.

Apparently the heat pipes are filled with something like r134....a refridgerant. The stuff is heated by the side connection to the hard drive, rises as a gas to the top of the heat pipes, is cooled and returns to the bottom of the pipes as a cooled liquid. Something like that anyway....heh.

I still cannot see the setup working very well if it is installed in a 5 1/2" bay without any airflow. (The link shows the setup) Like where is this heat going to anyway? It would remain trapped in the copper pipes if there was no airflow.

Now if you installed it in front of a fan....it should work fairly well. However, the side heatsinks only attach to the two sides only. I think they could do better.
