New corsair fans fail to be monitored.

Hello all,

Thiis is my first post, but long time reader. My issue is that I can't get a reading for fan RPM's.
I have:
Asus sabertooth 990fx + phenom II 980 BE + 16gb Crucial ballistix at 1600 + Asus gtx 660 top + 750wtt antec power supply + samsung ssd + WD 500gb green.

The fans in question are: Corsair SP 120 double pack + corsair AF 120.

Previously I had three cooler master sickle flow 7.99 fans and they where reading on my AI suit II just fine. Coolermaster fans where too loud. Now whith the premium price corsair fans they hardly run at full speed except for the one sp 120 plug into the cpu opt port. Af120 is on the chassis door pluged into the mobo pins as well as the other 120 that the cooler masters previously plugged into.

I've already uninstalled AI suit and re installed to rule out updates. Any one having the same issues?

PLEASE HELP. Thank you.
