My setup is AMD FX-6300, MSI 970 Gaming, and a AMD Radeon RX 460. My CPU has been idle at 60-70 C and I'm not sure why. I know I don't have the best air flow but it's never stayed at this temp while idle only when playing games. Any ideas?

When you applied the new thermal paste how much did you use? You only need just a little, small pea size dab in the center of the CPU, otherwise the paste doesn't allow the heat to transfer to the CPU cooler properly. To much paste and it inhibits the heat from transferring to little the cooler wont make proper contact with the CPU.

Use rubbing alcohol as pure as you can get and a coffee filter to clean the surfaces. alcohol evaporates with out a residue and coffee filters do not leave lint behind.

most likely the issue is with the cooler and how it is attached.

Download AMD OverDrive http://www.amd.com/en-us/innovations/software-technologies/technologies-gaming/over-drive and install. Next look under hte CPU tab and see what the thermal margin is saying. This temp reads backwards to most other things in this way, When the the temp reads 50°C then you have 50 more degrees the CPU can heat up before it starts to throttle. IF it reads 0°C then the CPU will start to throttle the speed to cool down.

AMD uses an mathematical algorithm to Guess at the CPU temp that is shown in other programs. Because of this the temp reading is often wrong especially when at lower temperatures. This is where overdrive comes in and tells you how close you are to overheating instaed of what the temperature might be.

Please report back what the temp reading is on thermal margin in overdrive.

The issue may be due to a bad reading. Try Overdrive as indicated by bgunner, and post us screenshots when possible.

The stock coolers on the FX series are considered useless by most builders. It doesn't explain the sudden jump in temps, but it is a good idea getting a better one.

Okay, you are definitely overheating here... You only need 6C before reaching the max temp of the CPU.

I suggest trying to clean you heatsink and fan once again. Check if the heatsink is actually tightly attached to the top of the cpu, and no gap is present.

Check if it is turning fast enough as well. (the fan) I assume you don't overclock?

I probably used too much thermal paste but it wasn't much more than a pea sized dot. I don't have any on me right now but I will clean and replace it as soon as possible. Thanks for the help.
