It seems both your motherboard and AIO might be affected by overheating. This sounds typical given the high temperatures in Blackwater Full with MSAAX2 and the GPU being overclocked.
The radiator might not be receiving enough airflow. The coolant temperature is very high.
I had my local computer shop construct this for me; they said the fans are arranged to improve airflow. The front 260mm radiator faces outward, pushing cool air toward you. Below it sits a smaller 160mm fan drawing air in. Then another 160mm fan on the back expels the warm air. I’m not very experienced with this setup. I should note I’m in the attic of my house—a loft—and it gets quite hot there. During summer, I need two large AC units running constantly.
You need a 160mm fan setup since the case only fits 120mm or 140mm. The Corsair H100 has a 240mm radiator (two 120mm units). You can either use two 120mm fans to push air into the case, or have one pulling air out from the back and another bringing it in from the sides.
There should be one intake and three exhausts in a hot room. Remove it from the heat, and use the radiator as an intake since it brings in more outside air. Making the radiator the exhaust for the whole unit means either forcing warm air into it or not providing enough air overall (because the case lacks sufficient openings).
I had the Corsair H100 240mm Exaust at the front and a 120mm fan intake at the bottom. Should I just flip the radiator on the front to draw in air, or is there another way? I’m really unsure about this setup.
You're experiencing high temperatures upstairs, and you're curious about adjusting the H100i's airflow direction. There might be a video that explains setting it to draw in rather than exhaust air at the front. You might need to reverse it and secure it properly. It sounds like your current setup isn't providing enough airflow, even though you have intake fans and exhaust fans.
Your current setup includes three exhaust fans and one intake fan, which isn't optimal. You could simply reverse the radiator fans so they draw in air instead of pushing it out. For best performance, front and bottom fans should pull in cool air, while top and rear fans should expel warm air. If you prefer more air coming in than going out, or equal amounts, that would be ideal.
