FX-8350 Overheating

I have an overheating problem with my AMD FX-8350 ever since I bought it. When encoding videos, running complex image filters and similar tasks, the processor easily heats up to 75 °C and the PC shuts down soon after. Everything (frequency, voltages etc) should be at default settings. I already switched my old Zalman cooler for a Cooler Master one, with only little improvement.

One thing I noticed is that overheating doesn't necessarily happen during gaming or even when the processor is at 100% usage. But it happens with high probability when for example encoding videos. What I tried was running the stability tests of the AMD Overdrive tool. I noticed that the processor heats up to an acceptable temperature of 60 °C when I try the CPU tests 2 to 7 but when I run CPU tests 0 and 1, the processor instantly heats up to 70 °C and continues to get hotter. As far as I know, tests 0 and 1 test the first and second cores only.

Under Linux I can set the cores to use for a specific process with taskset. I started an application that uses lots of processing power and had it utilizing one of the core number 2 to 7, getting normal temperatures. But the moment I set it to core 0 or 1, the temperature rose significantly (over 70 °C).

How do I stop my processor from overheating in these cases?
