FAQ

Q: My processor is running 55C under load. Is this normal?

A: Safe CPU temperatures are 60 degrees Celsius and below. It may still run fine with CPU temperatures, exceeding 60C threshold by a few degrees. Running the FX-8120 close to 70 degrees and higher is not recommended.

Q: I have an AMD FX-8120 CPU. Is it possible to upgrade it?

A: Probably yes. CPU compatibility is determined by your motherboard. Please check CPU-Upgrade.com website for CPU support list for your board.
