Spode's Abode, takes a look at a 60mm to 80mm Fan Adapter

Spode's Abode, takes a look at a 60mm to 80mm Fan Adapter

What do you think about my idea?

I have seen these since they have come out and was wondering about the rebound turbulence verses going straight down as in the pics.

Not as much resistance @ the bottom of the adapter.

Please forgive my great drawingz

HSF geometry is a much more complicated subject than it might appear to be at first glance. For instance, there's a reason why the infamous Delta 38 is so popular. Delta really did their homework!

That it takes a 68 cfm 80mm fan on a fandapter to equal the cooling effectiveness of the 60mm Delta 38 cfm still amazes me.

Thanks for showing us your idea. Please keep working on it. CPU's aren't getting cooler as long as we demand more and more from them!

Great idea there but I do have a suggestion. The middle of the adapter should be narrower than the exit(heatsink mount) giving you an hour glass shape. This would let you do 2 things; keep the velocity up & maintaining the volume & allows you to keep the mounting screws outside the path of airflow keeping it more efficient. The design is used in cars & it is called a velocity stack.
