AMD fx-8320 overheating?

Hi there,

I've built my first gaming pc about one year ago and untill recently it worked perfectly. But since about 4 weeks now, the cpu temperatures keep getting hotter and hotter. The temperatures with only skype and google chrome opened (taskmanager says usage is around 0%-2%) went towards 50-55 degrees celcius.

I am running an AMD fx-8320 cpu with the stockfan. I have 1 case-input-fan that came with the case and the PSU is supposingly my output fan. I know this may not seem like a good airflow but it worked fine at first, so I decided not to buy an extra input- and exhaust fan.

I initially thought I just had to re-apply some thermal paste, so that's what I did. I bought the silver paste that is meant for overclocking and stuff like that at a local hardware store. I applied it and since the heatsink got really hot when the pc was running I assumed that it was applied correctly.

After re-applying the thermal paste there was little to no difference and the temperatures kept increasing. After being on google chrome for 10 minutes while skype is active in the background HWMonitor tells me I've had temperatures between 49-64 degrees celcius. This really worries me. Especially because the cpu fan runs at 5800RPM (speeds I never used to reach before) and makes a lot of noise. It really sounds like the pc is screaming for help xD.

What could be the cause of these insane temperatures while the pc is being 'idle'? And why does this happen after about a year and not directly after I built it?

P.S. I may need to add that when I open the case while the pc is running the temperature drops about 5-8 degrees celsius. (I am using the Fractal Design core 1000 which doesn't really offers a lot of airflow).

Thanks in advance,
Jacco

You can use the splitter for more fans, but you need make sure don't add too much fans because the fan-header usually can support up 1Amp only, if you use too much fans, it can be killed. Double check the fan spec first make sure it has less than 0.2~0.3Amp, if you are plan to use three. e.g. this 92mm fan has 0.15A http://www.newegg.com/Product/Product.aspx?Item=N82E16835119102 so you can use three, your case use 92mm in the rear.

If you use the splitter, all fans will run same speed.

The PSU's fan is only for the PSU -- it doesn't really help get rid of any heat from the case.

At the least, add another rear case fan (to match the front case fan), & see how that works. If your case can handle it, try also adding more fans -- most usually have an option for a side and/or bottom fan, plus at least 1 top fan.

This is just the stock cpu cooler and the MB is the ASUS M5A78-L/usb3

The motherboard doesn't support any more case fans, but I've read about a splitter for the connector. My question about that is; doesn't that split the voltage too? So that if I add 2 fans all fans spin 3 times slower (because there are 3 instead of 1)?

I mean like, if you use 3 fans instead of 1 wouldn't the individual fans run 3 times slower than when you only connect 1 fan (since splitting the cable could split either voltage or amps). After doing some research the splitter indeed splits the amps.

I'll look for a good exhaust and cpu-intake case fan (there is an option for that in the sidepanel)

Alright, I think you guys deserve a big THANK YOU!
I've replaced my stock fan with the CM Hyper TX3 and added a 92mm exhaust fan in the back. The temperature dropped from 55-60 to ~35 degrees celsius.
