I have an AMD 9590 8 core 4.7 GHz processor. At normal operation it runs about 31-35 degrees Celsius. However when I use 100% of the pressing power when I'm multitasking or compiling complex programs I have failsafes in place to shut down after 30 seconds above 90 degrees to prevent damage. I've double and triple checked the thermal paste and the placement of the of the cooling block for the pump. The I've used higher cfm fans and it only made the problem worse. I have also reconfigured the direction of the air flow with at least 10 different configurations. And the current one I have is giving me the best results. There is no over clocking in this rig. Short of building a custom water cooler or shoving the tower in a fridge ( I know condensation and such) . I'm out of ideas.
