I recently build a custom watercooling loop for the first time. I originally had a dual 80mm, 240mm, and 120mm 45mm thick rads in a GPU CPU loop in a Coolmaster XB EVO. I was using software Hardware Monitor to check temps. It showed that my CPU and GPU where around 70 C. I recently upgrade to a Thermaltake X2 case with a 120mm, 240mm, 360mm 45mmm thick rads, and have a temp sensor in the loop. I also using the Corsair Link software to monitor temps and control fans. Corsair link is showing my CPU temp to be 123.3 F at idle and GPU temp to be 138.2 F at idle my water temp is at 70 F. I not understanding why my parts are running so hot. these aren't the system temp I figured I would be running at idle. I did the TDP calculations and the rads are more than able to handle the max TDP of my system. my room is cold like always 64 F so I'm not seeing a difference in water temps at all. the water isn't raising its temp. I check to see if thermal paste was good on both CPU and GPU and they are nice thin layer and not tooo much. Also to mention my GPU is a full block and thermal pads are installed correctly.
