I think my current design is weak and falls short in a lot of areas - it's not reliable, efficient, or economical. It's two designs smudged/bodged together. So, this being a new, ground up design, no components are specced.
As airflow varies with movement, fan speed isn't important when moving. However, when stationary, other load variations in the car can cause the fan to speed up or slow down. This also makes no difference, but some are annoyed by the change in sound as, say, the A/C clicks in and out. Personally, I don't mind, but it's a requested feature.
