if the engine needs 20% fan thats what itll get.
if it needs 35 or 55% itll get it..

I use one of these. It is a killer set-up. I just assumed the OP was trying to use some type of factory set-up instead of an aftermarket deal.

I have mine controlling dual 16" fans. I think they come on at 185 degrees and slowly increase as the engine heats up. When the AC kicks on with the trinary switch, they come on full blast.
