Soldered fins?

Are there any Scythe coolers with the fins soldered to the heatpipes?

Most of the reviews I have read say that Scythe's coolers are friction fitted or thermal glued.

Hi,

there is only one cooler in our portfolio with soldered fins, thats the Orochi cooler. Why you want to know this?

Curiosity.

Soldering is supposed to improve thermal efficiency, so I was wondering why Scythe doesn't do this to more of their coolers. (At least to their higher end stuff)

Things are not that simple. actually. Look closely at fins that are designed for press-fitting and you'll notice "bottlenecks" around heatpipe holes that widen the contact area. Orochi uses a different (cheaper?) technique of fitting fins that prohibits making these "bottlenecks" - otherwise it will be impossible to drag the fins (pre-stacked) on. That's why they use soldering - to compensate the losses.

As for combining "bottlenecks" and soldering - I can say that technologically it's a complete PITA that leads to a very little improvement in terms of cooling capacity. Just isn't worth the trouble.

Soldering also holds fins more firmly than simple press fitting

I have used a tower heatsink from a company whom I will not mention other than it's name starts with an "X". It's top fin is loose.

I have also had a loose fin with the Scythe Ninja, although it is only partial.
