I just got a new 1440p monitor and decked to use my old 1080p monitor as a second vertical monitor and ever since then iv been playing borderlands 2 and notice that my cpu and gpu temps have been in 80c range. I have a Ryzen 7 5700x3d cpu with an AIO cooler. My GTX 1660ti sounds like a car engine any time i play Rainbow 6 too.
