GTX 970 Strix OC DirectCU II / idle temps

I bought the ASUS StriX GTX 970 OC DirectCU II ( SLI soon ) i and want to ask you if the idle temps are not a bit too high.

Now i have 51 degrees, only Mozilla Firefox is opened.

I attache here more details about the card.

I use Windows 7 Ultimate x64, latest Nvidia driver - 347.88

Please help me, thank you
