Most of MSIs non-reference PCBs are named Hawk, Lightning etc.
Yup the TF3 fans are getting audible at 70%
but its overclockability is great
I can do 1300/1450 with 1.30volt just for benching and stable daily at 1260/1450 with 1.30volt
Just in case you didnt notice, GTX570 TF3 has different component than GTX570 TF2, GTX570 TF3 has 6+1 PWM while GTX570 TF2 and reference GTX570 has 4+1 PWM. So I think MSI Hd7870 TF3 OC has different component/layout from reference HD7870.
