AMD FX-8320 CPU overheating with stock cooler and clock

Hey there, this is my first build and I'm using a FX-8320 and a Asrock 970 Pro3 motherboard. The CPU idles at temperatures that seem way to high. AMD Overdrive tells me that with just Chrome active it is sitting at 37 degrees Celsius, and hardware monitor says it is at 33 degrees Celsius.

Bear in mind I have not touched any settings such as voltage or clock speed, and I added two extra 120mm noctua case fans to help airflow inside the case.

I have tried moving the CPU cooler, I have cleaned the old stock paste and reapplied it with Arctic Silver and it still reaching temps way too high for what I'm asking it to do. When running all 8 cores after about 5 minutes of game play the whole system shuts down, I assume because it is too hot. I reduced it to 4 cores, and it still reaches 65 degrees with CS on low settings, a temperature I do not feel comfortable running on for hours at a time. Also, interestingly, Overdrive reports that the CPU is at an ice cold 20 Celsius when gaming which is obviously wrong.

Please help, any advice or assistance would be appreciated.

Thanks- Sirthatal.

Edit: I also have a GTX 750ti which should make short work of CS on low settings, right?

Well, if the plastic strip has been removed from the underside of the heatsink, thermal paste has been reapplied, the heatsink is seated correctly and the CPU multiplier or VCORE hasn't been changed, then I'd say that the heatsink is faulty, or the processor is.

You could buy an aftermarket heatsink as a quick and dirty solution, but I'd be inclined to send the processor and heatsink back if they're under warranty.

Yup. It's the copper of the cooler, a light coat of paste in between then the CPU. Nothing else.

I'm not so worried about the idle temps so much it's just how it kills itself playing fairly easy games on low settings on 8 cores. With just four cores it struggles to stay under 65 Celsius. This is with two extra 120mm fans blowing almost directly on the cooler as well, not just the stock cooler. I just thought the stock cooler was capable of cooling stock clock.

No brand new. I'm running the cpu on two cores now just so I can play CS without it going over 50 degrees. I'm going to take it to pieces entirely again and see if putting it back together does anything.

Just letting you guys know that it was an out of date driver! The CD came with an old one so when I updated via the asrock website it must have changed some settings and now it doesn't go over 35 during boot up. So happy!
