Not very often am I surprised and impressed, but this is one of those times: a 92mm tower form-factor with the heatpipe density of a 120mm by stacking heatpipes on top of heatpipes. This is actually a very good idea and I am surprised I didn't come up with it first

Judging from the stats there, it could be twice as effective per unit mass as some other common heatsinks.

0.12 c/w when xigmatek's website says the 1283 is 0.16 c/w...

i highly doubt that it will be twice as effective. but maybe 2-5 degrees sure.

I said per unit mass so I'm talking about efficiency. So what I mean is that a 400g heatsink could perform the same as an 800g heatsink.

yea i read that but didnt feel like correcting myself.

whats your prediction on temps

i dont think that it will be as good as twice the mass unit either. while heatpipes are very crucial to performance, i dont feel that simply adding more necessarily gives a big boost

While reading your post, I started to think whether increasing the radius (thickness) of the heatpipes would be more efficient. Then another question came to my mind; what about flat heatpipes going through the fins?

A quick search on Google and found this Auras prototype with flat heatpipes. Interesting idea.

Thermalright has had the Ultima 90i available for quite some time. It has a very similar heatpipe layout, and the general dimensions match as well. Except for the direct-touch approach (kind of irrelevant due to the second set of heatpipes), there is nothing new here.

The scythe orochi has 5 heatpipes directly stacked on top of another 5.

The top row of heat pipes probably aren't adding that much to the cooling process, but since weight isnt as issue with this heatsink then i dont see how it could hurt at all.
