So I've been noticing that my GPU in my Acer V3-571G has been idling at 68-72 degrees Celsius according to MSI Afterburner, now I'm not sure whether that's normal or not, I have it on a cooler pad with good air flow underneath it but the temps are never below 68 and will slowly climb to 68 after booting, even without load, during gaming it will get as high as 96 degrees (if it reaches that high I usually let it cool down for a bit). Are these "normal" temps? I haven't checked it for dust yet so that could be a factor.
contact acer support, if it's under warranty they should check the cooling fans, replace thermal paste. if it's out of warranty... get it to a laptop repair center and they'll do this for a relatively small fee. the temps are too high i think and can cause serious issues if you keep using it like this.
