Think I will just save my time and money and leave the fans at full speed, no big deal as I've always said, not that noisy at all to me, put it this way, Ive had fans over the years 100 times worse, these are by no means what I would even put into the "noisy" bracket and thats on the highest setting, but each person to thier own thing, its whatever your happy with, but yea, I think I will give that thing a miss that will cost extra money and hassle just to read the fan speed, they should (I turst) be running at full speed, soon know if my temps go up, put it that way, lol.
