I just took a count of fins on my 2-342 single pass core.

12 per inch. A much lower count, perhaps due to the fact the core is also 1 15/16" thick.

It's face is as large as the Commodore, even a bit wider (6 3/8"), but is close to 50mm thick compared to the 30mm of the Commodore. Yet the Commodore should have more actual dissipation surface due to double the fins per inch while it's also 3/5 the thickness + the added benifit of greater air flow.

As I'm sure you've had expericance with both Cathar, how much of a increase in air flow do you estimate the Commodore gives vs typical thick US style ones with a much lower fin count? And more important, how large is the improvement in cooling?

Thanks
