Hydra fan question.

Does anyone know the fan size difference between the small and large Hydra fan kits?

Does anyone know the fan size difference between the small and large Hydra fan kits?

I was also wondering about this.

The small fan is the same size as (and probably is) a CPU cooler fan of the later 486 era, so say about an inch-and-a-bit square. It spins fast and blows at fairly high velocity.

The large fan looks to be the standard ~3.5" square fan, as found as a power supply or case fan in PC's forever. I don't have this one, but I presume it blows at a lower velocity than the small.

You can see pics of both at Heartfelt (where I got mine).

According to heartfelt: "Fan measures 3 5/8" square with a fan size of 3 1/2"".
