Hello everybody! I recently bought this iMac, which was used for 2 years. The original mac is not modified. I have another such iMac, so I can compare it. The problem is in the CPU (SRG19) cooling. When I load the CPU, the temperatures rise sharply to 80-95-100 degrees. Along with it, the GPU temperature rises. The cooler raises the speed to the maximum, but the CPU is not cooled. When I load the GPU, the cooling system works fine, the CPU is not heated. On another iMac, the temperatures are different in the load and the cooler works at minimum rpm. I disassembled the faulty iMac and put a new CPU there (also SRG19), filled in a new thermal paste. The problem is not solved. Help people!
