I built this as part of my Christmas present to myself last year. I cheaped out on my graphics card (6650xt) after splurging on a 4k 144hz Monitor. The 6650 did a great job for the most part but I had to use aggressive upscaling and dialed back alot of settings. I’m giving the card to my nephew today!
Quick update for you. I let the Adrenaline software run a log for about 3 hours while essentially doing nothing. It fluxed between 62 and 58C the entire time. I haven’t gotten into any really hard core gaming tests but my son playing Minecraft and me playing Diablo IV never got it above 69c. I’m not even sure if I heard the fans.
