Hello. I have a custom built desktop. In this desktop, I have 2 RX 480 8 GB (each one only has one fan), 16 GB DDR3-866 ram, 1 TB SSD, Xion 850 watt power supply, Corsair 300R case, a core i5 4690K, and a Noctua NH-U9S 46.4 CFM CPU Cooler. I have not changed out any fans other than the CPU cooler. When at full load, which happens a lot, my GPU is at 90 C, and my CPU is at 70 C. I was wondering what I could do to fix this. I am not very experienced with computer building so I am not sure what I should do. I am trying to keep my room cool but can not seem to cool it down. Thanks in advance and this is my first time posting.
