Messing up thermal paste

Hi, I'm wondering if I'm applying my thermal paste wrong or if it's my cooler. With an AMD 8320 I'm hitting between 50 and 60 degrees C idle at BIOS. My cooler is stock and the paste is some cheap stuff, with thermal conductivity of 1.93W/m-k.
Thanks.
 
Solution
In BIOS, the CPU runs at full speed. Check idle temperature in windows or some other operating system that uses CPU thermal management (was it Cool'n'Quiet for AMD CPUs?).

You should check what temps people are getting with this CPU, maybe it's normal. Of course, it could be the paste, or even the cooler.

What are your temps when you are actually in the OS? If they are still in the 50s and 60s at idle, then yes, it's possible that you've messed up the paste somehow. Too much is as bad as too little. It's always worth investing in quality paste, even with a stock cooler. The stuff that comes with a Hyper 212 Evo is pretty good. Not the best, but probably better than whatever you're using now.

Your CPU temps at idle aren't a good sign. Good quality thermal paste is actually cheaper than you think and it's just as important to select a good thermal compound as it is with anything else in your build. Some thermal compounds can last up to 8 years before becoming useless. When installing your cooler, did you ever lift it up off the CPU when you had thermal paste on the processor? If you lifted the cooler and then tried to replace this, it would create air pockets in the compound which will directly affect the CPU's surface to cooler. Also can be quite damaging as the thermal compound is very strong/sticky and even rip the CPU out of the socket which I have seen quite a lot.

I'd suggest investing in some Arctic cooling MX-4 Thermal Compound. It's cheap and reliable and I've knocked off quite a lot of degrees using this myself.

I recommend watching this video to show exactly how much thermal paste you need because it really does spread over the chip under pressure. Gives you a little insight to how much you actually do need.
