I bought a new fan for my car - Derale 17119. I don't need a new on but I like to have extra stuff and it is cheap enough to have as a spare. The fan in my car is 19" and very likely not original.
Comparing the new and old fans, the dimensions are the same but the notable difference is that the old one has a continuous curved blade while the new one has it bended in three straight sections - probably the difference is due to manufacturing costs. Now my question is, will there be a difference in efficiency between them? The basic difference seems to be how the blade is curved. I don't know if the leading and trailing angles are the same. In the picture the old one is on the left and the new one on the right.
