hi guys got two gtx670, and i just got a feeling something aint right, and kinda hard to explain,. i have v sync on so only going to display 60 fps. but gpu temperatures are at about 52 -58 c and this seems a bit high to me and of course the fans are going faster which you would expect but i never used to get this increase in fan speed about a week ago with v sync on , system was nice and quiet .the normal noise that you get from gpus fane sounds a little differnt just louder really and am a little concerned. just seems that the gpu are getting a little bit to warm when they start to do any work, i am looking at gpuz read out and it says both fans are working but even on desktop doing nothing 38c would u say thats right. have got latest drivers , cleaned install as well, even at this moment while typing this the noise from the fans was still louder than what it was say a week ago. could it be dust in them already and needs some compressed air sprayed in ? . sorry if this sounds confusing, but it is to me as well, but i just think there is something not right or maybe gpu fan bearing maybe or something on its way out, thanks for your time.
