I had quite a few problems with uguru until I had updated to the latest version, you might want to give it a shot. The latest version that I've seen is 3.107 and you can get it from here:

I've got my TT120 plugged into aux1, at first it seemed like it would control it when plugged into the cpu fan header, but it started acting up and wasn't speeding up and slowing down sometimes after reboots. After I moved it to aux1 those problems went away..
