Can't Control CPU Temperatures

I'm, once again having some problems controlling my CPU temperatures. I've been trying a couple different methods of solving the problem, but I have not reached a working solution. The skinny is, my AMD A10-6700 is fluctuating between mid 50 C and 60 C at idle, but goes into the mid 70s and even up to 80C while playing something as simple as Minecraft. I have one case fan installed as a rear exhaust fan. My heat sink is the Hyper TU2. I've contacted CoolerMaster customer support, and they have recommended I replace the thermal paste. I've used some Arctic Silver 5 (size of a grain of rice, just installed it today). Temperatures have improved slightly, but not enough to show improvement. I have a discrete GPU installed, the Zotac GT 730, which could be raising the heat of the processor, but Its temperature is pretty steady at 30 C idle and 37C at the maximum load I have put on it (not much due to the CPU temp). Any suggestions? I've been posting a couple times about this along my road of many different modifications, so I'm sorry if I have appeared annoying or repetitive. I'm new at this and need all of the help I can get. (FYI, the temperatures were obtained using both Speccy and HWMonitor)

Unfortunately, the cm t2 isn't much better than the stock cooler, with room temps in the low 20's, you'll still see core temps at full load broaching 90+.
A good start would be to install an intake fan. As it stands, since the exhaust vacuum is strongest near the fan, that's where all the supply will be, leaving the gpu/cpu to recycle hot air through the heatsinks.

I would recommend a replacement cpu cooler, along the lines of the hyper212 EVO or plus. What you are looking for is cooling ability in wattage, either of those capable of 180w, double the heat output of your cpu. The t2 TDP is barely over your cpu's TDP, so ends us as barely enough at higher temps. But start with the intake fan, and go from there.

I've also been monitoring clock speed. I am not overclocking at all, and in fact have given my CPU the maximum clock speed range in AMD Catalyst control center. Through Speccy, I have noticed some or all of my cores briefly clocking up to 4200 MHz, and then falling back down to the lower ranges. This seems out of place, given that the maximum clock speed on my CPU is 3700 MHz. These fluctuations in clock speed seem to correspond with the fluctuations in temperature.

make sure the heat sink on tight. if it not the thermal paste and heat wont move off the cpu. the cpu you have has a built in gpu too. check in the bios that it off. sometime with some mb it have both gpu and apu on. also make sure your video cable on the gpu and not on the onboard video so it turns off and keeps the chip cooler. also in the bios check that the system is running in stock speed and voltages. some mb like asus have performance mode. this can change the cpu speed or over volt the cpu and make it run hot. if case airflow is an issue see what the cpu temp do with the side of the case open.
