( this thread for 7970 Sapphire Dual-X owners )
Last year I got a Sapphire Dual-X 7970 3gb here in japan for ¥6,500 ( US$58 ).
I successfully flashed it and got it to run at 5.0gb/s in High Sierra and it now runs nice and quiet with an EVGA PowerLink connected.
This model has two fans and I eventually noticed that the rear fan spins up at startup and then shut down.
Tonight I ran Sapphire's Trixx in Win 7 and sure enough when I entered the FAN section in Trixx the rear fan started spinning.
Trixx showed that tonight ( March = winter in Japan ) the ambient temp was 24°C and the front fan was spinning at 28% of capable speed, the 2nd. fan was not spinning
Japan's hot & humid summer is rapidly approaching so I have set the fans to 60% when the card's senors hit 50°C. Hopefully that is when the 2nd. fan should spin up.
So apparently the 2nd. fan spins up when the card gets to a set temp.
I will see what happens when where I live in Japan hits 40°C. outside.
I hope that this info is useful for any cMP Dual-X owners.
