Stock FX-6300 too hot under load

Hello. I have my computer for almost a year now. On July, I got my R9 380 4gb. Since then, I started gaming on some quite high graphic settings. But, as I live in a cold brazillian region, I haven't had any trouble until these last few days, as my CPU stock cooler fan started getting loud. So, I decided to start checking temps (using both AMD Overdrive and MSI Afterburner*), and tonight, a kinda cold night (~13ºC outside), I got surprised when saw these temps while under load:

When idling, I just kept MSI Afterburner running for around 5 minutes;
When gaming, I ran Tomb Raider on max settings for around 5 minutes;
When stressing CPU, I ran IntelBurnTest for around 7 minutes (enough for the temperature to stabilize);
On the last one, I [strike]set fan speed to 100% on Afterburner and[/strike] ran IntelBurnTest for the same time as earlier, but I also took the side panel off and faced a big ventilator towards the motherboard, which apparently caused a very good airflow inside the case. Edit: Also, I stopped IntelBurnTest a little while before taking the screenshot. The final temperature should be 81~82ºC.

I cleaned my case when I installed the GPU, but never checked the thermal paste, as I'm not familiar with it. I am actually not sure the guys who built my PC** even put it on.
Also, I got a Corsair Hydro H45 on its way to my home as I'm willing to try some overclocking as soon as I get this problem fixed.

So, my questions are: What could possibly be going wrong? Will the H45 solve my problem, perhaps?

*I checked the temperatures were consistent with eachother.
**Asus M5A78l-M/USB3, 2 x 4gb Corsair Vengeance, R9 380 4gb, XFX 500W 80 Plus Bronze. All of it on stock.

Likely, yes. There's no reason your CPU should be running that hot at stock. I would try as a duct-tape fix to reseat the cooler, and if that doesn't help, wait until you receive the new cooler and install that and go from there.

Reseat the cooler, see if that makes any difference. If not, there's likely a problem with it (if this is a new problem), and the new cooler will likely aid that drastically.
Also, I don't believe Afterburner controls your CPU fan speeds, just your GPU fan speeds, although I could be wrong about that.

You are right, actually. Just checked.
I reset it before doing these tests.
Is it likely to be a CPU cooler issue, then?

I will pick this a solution for now. When I get the new cooler, I'll install it and test. If I have any more problems, I get back to it.
Thanks for now.

Hey Marx. Looking through your post, I can give you a little bit of information.
Can you tell me if this is your motherboard? Please note the left of the CPU socket has no heatsink, just the silver capacitors and black VRMs. http://www.newegg.ca/Product/Product.aspx?Item=N82E16813131942

If this is your motherboard, I would highly recommend against overclocking. Frankly, I don't think you need a new CPU cooler. Can you tell me what your CPU TM (Thermal Margin) is reading on AMD Overdrive, under load? A TM of 20 is on the low side. Without overclocking you should be in the 30s.

If you have the stock AMD cooler on, it comes with thermal paste preapplied so whoever built it couldn't have forgotten to put any on, thankfully!

Have you had any crashes? Is your only worry the temp reading from Afterburner?

To go with the above--AMDs temp readings have been known to be... less than stellar. Essentially, when you're testing the CPU, does it throttle? If it's throttling, there is an issue. If it isn't throttling... I don't like the temp readings, but it's not exactly unheard of that your stock CPU cooler could've failed.

First of all, thanks for the response.
Yes, that is my mobo.
As I said, I was using Afterburner only after checking its temp reading was consistent with Overdrive. Anyway, my Thermal Margin on OD reaches -12ºC after only a few minutes stressing my CPU.
Maybe something could have happened to the thermal paste when I installed my GPU?
And no, I haven't had any crashes so far.
Edit: My worry is about the temps overall. If these softwares are misreading it, I'll be ok just letting it the way it is.
Maybe it was a mistake buying the watercooler, but I'm willing to change my mobo and, then, overclock my CPU, so maybe it'll be useful in the future.

I'm not sure how to categorize a throttle, but, as you can see from those usage graphs, both on second and last tests, it seems to use less CPU some times.
If you mean while gaming, I don't see it at all. Even reaching 82ºC (at least that's what my motherboard reads), everything runs smooth.

I finally took courage to open my case to take a look at my CPU cooler, and that's what I found:

After some vacuum cleaning, that's how it is now:

By now, my temps seem fine: got max of 45ºC (thermal margin of 25ºC) while gaming and 64ºC max (thermal margin of 6ºC) while stressing. These temps are still not ideal, but whenever I get a better screwdriver, I'll clean my CPU better.
I'm terribly sorry for taking your time, guys, as it was just a detail I should've noticed earlier. One last question, though: Is there a possibility the high temps I was getting somehow damaged my CPU?

Dirt and dust will certainly do it :p If you have a vacuum/compressed air that would also certainly do the trick. You can pop that fan off of the cooler and then put it back on once you're done.
It probably lessened it's lifespan a slight bit, but not anything significant that you would end up noticing.\
As for a throttle, throttling occurs when your temps on your VRMs or your CPU are too hot generally (there are other reasons, but this would be the reason here), and this forces the CPU to run underneath it's stock speeds trying to save itself.

Yeah, that's what I meant when I told about the screwdriver. Mine isn't good and the screw is too tight, so I couldn't do it for now.
Thanks for all the info.
