Hey guys, I made a homebuild a few months ago and I was wondering about my gpu's temperature. I have the NVIDIA 470 and I have a thermaltake Element G, I looked on some forums about temperature and someone said safe is mid sixties, well I am using vtune and it says my fand are at 44% with a GPU temperature of 72C, this sketches me out a bit, when I turn fans to 54% they get a bit louder and my GPU goes down to 63C. Bottom line is in dynamic cooling fans are at 44% with 72C is it safe to put fans on 54%? and my Element G's rear fan is not working could I get help with that too? Thanks, Regards.
