I am new to the community and just finished my first gaming PC build. With my new build, I am having trouble keeping my Ryzen 5900x at a good temperature. Measuring in HWinfo 64 my CPU Die in game is 90 degrees Celsius and it idles around anywhere between 60-70 sometimes higher. My GPU is a 3080 12gb and its current max is 56 degrees in game. I am using the Arctic Liquid Freezer 240mm which is set to full in the BIOS with both fans running and the small pump head fan turning. I am using the Lian Li Lancool 2 mesh case which comes preinstalled with 3 front fans, and I also added 3 more case fans (two on bottom, one exhaust in the back). This is my first PC build and I am very new to this, but it seems like I should not be having trouble cooling the CPU with the cooler that I have. I also have read that the 5900x tends to run hot. Does anyone know why this is happening? I also have been having a separate issue with my monitors where the right one tends to flicker randomly. No idea if that could be related at all, but thought I should mention it. Thank you to anyone who can help me with this.
