I got the idea that it might be the fans on the Radeon graphics card that take too much of the air in the cabinet, so that the air flow through the cabinet becomes too low, to cool the northbridge and southbridge chips.The Radeon card takes air from the case and out the back of the computer. The original graphics card used only the air in the cabinet for cooling.From there I made a screen of cardboard so that most of the air for the Radeon card was sucked in via the air intake in the side of the computer, and it actually caused both onboard graphics GPU temperature and motherboard temperatures to drop from 83 to 71 degrees C, respectively 74 to 66 degrees C. The temperature of the Radeon card is around 60 degrees C, at high load. So that must be acceptable. So for now, that must be the solution. Subsequently, I drew and 3D printed a screen and mounted it in the computer.At some point, I try to mount a more powerful cabinet fan to see if it can lower the temps further. Thanks for all the response to this topic. They have been of great help. [IMAGE]Cardbord[IMAGE]Air intake in the side[IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE]Radeon air outlet
HiI have observed that the motherboard in my XPS 435MT (14 years old), gets up to 77 gr. C. hot in normal use. It is completely cleaned inside, but still gets very hot. I have used an infrared temperature gauge, to locate the high temperature, but without success. Has anyone had the same problem and how was it solved? cpu and gpu temperatures are quite normal, around 60 degrees C.
