I have an odd issue. If I flash CFW 3.55 this certain PS3 CPU idles around 60c , but if I flash any CFW based on 4.xx the CPU will reach around 90c with the fan going full blast around 79c. I'd just add some good thermal compound to it if it were to overheat all of the time, but it only does on newer firmwares. I shall in the meantime while waiting for replies go get some expensive compound and apply it to the CPU, but since it only overheats on CFW 4.2x, 4.3x and 4.4x I'm not sure what, if anything, I can do. Any suggestions?
