I have a GTX 1080 Founders Edition that I recently got from a friend. He had it in a small crappy case, so to make room, he took parts of the shroud off, and lost some parts. More specifically, most of the screws, and the little plastic window that went over the fins of the heat sink. My issue is, is that whenever it gets under a load, it throttles to around 70C, and I don't have much options. Should I just spend $50 on a cooler?
