On the other hard if you can get temperature readings in software level you can send them to a micro controller (Arduino?) which will control the fans accordingly. I think we are a bit offtopic though :) .
A micro controller needs equipment and knowhow. A circuit easily can be build to cause a wanted minimal and a wanted maximal speed. For my AMD CPU and my PSU with a large fan and my passive graphics everything is ok by default, no home improvement needed. But it's not a Laptop, such issues seem to be more common for Laptops. Noise caused by the computer seldom is OT, since we are writing about graphics fan noise it's not OT for this thread :). Btw. if the fan now should be louder than it was some time ago, the cause might be dirt.
