so i did some stress test about 10mins,set all fans to 1300rpm,the pump temp increased by 2C only,from 40C to 42C. i also attached a photo of my pc,from the front edge of my pc is about 7inches from the wall.
i tried setting the exaust fans and the rad to quiet mode and set the intake fans to silent curve,without pannels it dropped to 36.20C,with pannels it went 37.60C. run about 10mins.also tried setting all fans to 600rpm with pump at silent mode(with pannels) it went up to 40.40C
