I'm not sure if you will be able to do this.The sensors are part of the fans circuit so you cant really add it on.I am not sure if there is any other way to do it.

it cant be done. if you need fans with RPM sensors, buy new fans. (something better than thermaltake, too)

these are Chassiss's factory fans. i didn't bought them. maybe, youre right ))
can u guys recommend some 140x140\120x120 led fans?

i dont use LED fans at all, so i have no reccomendations there. Yate loon, nexus, panaflo are my non-LED reccomendations.
