AMD FX-8350 Temperature.

Hello,
I just bought a new case and moved all my components over, so that the airflow would be improved. I also replaced the stock CPU cooler for my FX-8350 with an aftermarket Arctic one.
I'm getting very high temperatures on the CPU when it's under load: idle, it's about 15-25 degrees Celsius; in a stress test, it got to 80 degrees when it throttled itself.
The thermal paste was applied correctly, as was the cooler. I have an exhaust fan out the back, two at the top and an intake at the front. What is the maximum temperature I should have with the FX-8350 when it stops being safe and hinders the life of the chip?
Thanks.

Don't know what to really tell you, other than having a Corsair H110i pushing the FX-8350, using all cores compiling LLVM/Clang's entire stack has it maxing out at 44 Celsius. It very well could be the Arctic sink is incapable of pulling nearly as much heat dissipation as the Corsair.

Those dual 120mm fans inside the Corsair 650D case and an RM 1000 PS has this system purring.

I have the Z11 plus case. I think the temperatures might be due to the heatsink not being correctly mounted. I'll check tomorrow.

If that were true, wouldn't I have lots of instability when it's at 80 degrees? Where did you get this number from? Could it be that the sensors are incorrect?

When you boot into the BIOS what are the default temps for your system?

What OS are you running and safe consensus is that 62 Degrees C is where your CPU temp should peak.

My system: Debian Linux Sid/Experimental 3.14 Kernel.


Running sensors from the command line:

mdriftmeyer@horus:~/Projects/LLVM$ sensors

k10temp-pci-00c3
Adapter: PCI adapter
temp1: +10.5°C (high = +70.0°C)
(crit = +90.0°C, hyst = +87.0°C)

fam15h_power-pci-00c4
Adapter: PCI adapter
power1: 30.72 W (crit = 125.19 W)
