I recently bought a Palit GTX 970 about 3 months ago and I have had no problems so far up until now. Recently (upon getting into Just Cause 3) I noticed a sound coming from the card. The sound is tough to describe but it's like a fast clicking/grinding like sound - almost like when you put your finger up against the blade of a spinning fan and you slow it down to a low pitch buzzing. It seems that this sound happens at about the 75 degree mark but now it has started making the sound at idle temperatures. I'm pretty sure that it's the fan as if I put my finger on the centre of the fan to stop it, the sound disappears. Any suggestions on how I might fix this?
