Interesting, I like them!

I'm really interested in seeing the quad results, I've been waiting for someone to make a slim quad rad for low speed fans for a while.

Slim radiators perform nearly as well as the double thickness types, I never understood all the hype on double thickness especially with really low speed fans.

FYI, the actual core thickness on slim radiators is 21mm thick, the extra thickness comes from the built in shroud, so it appears they decided to go with a slightly narrower shroud depth. It's one of those give an takes, make it thin so it's compatible with more cases and let folks choose to add their own shrouds, or go thicker to build more shroud benefit into the radiator itself. Different options...

Looking forward to some test results...

Sorry to hear the flaming from folks, I think all testers go through that. Folks are always skeptical. I always had one rule with I did my testing, I gave the manufacturer two options. Either I publish and tell the whole story, or they can opt out of the review all together. I did get a few that never made it, but most of them are generally pretty good about just getting the information out there from what I've seen. A review is always good exposure for them.

Anyhow, for what it's worth. Thanks for posting the pictures, and let us know more as you get some testing done.
Thanks!
