Gtx 570 overclock 800 mhz

I just finished overclocking my gtx 570 to 800mhz core, 1000 mhz memory and

1600 mhz shader.



All that at 1.000 mv.

After gaming 2 hours with bf4 and cod ghosts my temps was 72C max.



Is it considered safe ?



My card is the gainword gtx phantom 570 which i think is 6+2 phase.

So no problem with vrms?

I dont want to blow something!!

Thnks.
