I just purchased a refurbished Asus g750js-ds71 and my average CPU temp is about 65C but then under a load it has spiked to around 99C. My 870 is fine its normal temp is about 35 then peaks at about 75 which is what i expect. My Asus G74 runs at about 45C. I feel like 65 and 99 pretty hot should I return it for another?
