Well i use the stock wraith spire cooler, but i don't think it's thermal throttling because i monitor the temperatures of my cpu and gpu, and my cpu ia only at around 45°c maybe 47 highest, and turning the settings from high/very high to the most minimal settings only increase about 5-10fps, so i don't think it's my device capability either
