Hey folks. So the other night my computer shut down due to it overheating. Using AMD OverDrive the temp margins were single digits. I used some compressed air and cleaned off the heatsink. Now the loaded temp margins is upper 20s lower 30s. Since then I've gotten a CPU fan error message a couple of times. So, I'm looking to replace the CPU (stock) fan/heatsink. I know nothing about cooling. Is a good air cooled system fine or should I upgrade to liquid cool? The CPU is A3+ and the motherboard is an ASUS MA597. Any thoughts and input is appreciated.

the general idea is that Cooler master hyper 212 evo will be great value for money.. but you are always welcome to put better cooling on it,
but the evo will even handle some average overclock...

but yes if your 8120 is hitting single digits without any overclock on it - which means its over 50c (or maybe even over 60 which could be quite disasterous) you really need to upgrade the cooling,
my six core will have the temp treshold in overdrive up to about 70c but i think it's 62c for the 8 cores...
or was it 70c for the cpu and 62c on the socket for all of them... i always get confused about this :)

Maximum Recommended core temp for FX Processors except for the FX 4100 and 6100 is 61.1 degrees Celsius.
The recommended maximum core temp for the FX4100 and 6100 is 70 degrees Celsius. It is core temp. On
Hardware monitor it is the package temp. And on core temp it is core temp. This information I got from AMD global Tech
Support for North America. It would be wise to clean and reseat your Heatsink fan Assembly and replace the TIM or thermal paste with Artic silver 5 or better. See if that helps and or purchase and Install a decent aftermarket cooler like the
one mentioned in the previous post.

Thanks for the all the info folks. Looks like the Hyper 212 is the way to go. I like that it's only $30 on Amazon!



I have a Zalman Z95 (I think) case. It's nice as it has two smaller exhaust fans built into the sides. Plus room to add lots of case fans.

You don't need static pressure fans with a dust filter. Dust filters do not restrict air that much until they are extremely fine. Even then, they don't cause a whole lot of issues.

yep - static pressure optimized fans are more for radiators ... especially dense ones,

one prime example - the stock amd FX6350 or 8 core cooler with the whiny-tiny fan -
it actually works - i took it off and put a bigger silent-ish airflow optimized 92mm fan and cooling performance reduced

If I put a silverstone magnetic filter on my side fan and while playing TF2, my cpu gets really hot.

that doesn't say absolutely anything.

what case do you have? what are your fans? how many of them? in what arrangement (intakes and outtakes)? what cpu cooler/fan do you use? what is your cpu and motherboard? what clocks/voltage you run it on? what temp is really hot? what method did you use to apply termal paste? what paste did you use? what are your usual ambient temps? ...

and i would imagine static pressure optimized fans create static pressure - which doesn't say much about what happens on the intake side of things... but i might be wrong

i have a Define R4 with one 140mm intake that came with the case and two other 120mm ones that i had - all behind filters, and one 140mm exhaust that came with the case and my temps are more or less the same as when i open the case...

Like yanis31 said, there are way too many factors in that.

Honestly, I cannot believe you unless your system is that starved for air and you have a bad CPU cooler (or you mounted it wrong or applied the thermal past wrong, because I use one for the bottom of my case (the only place cool air is really being drawn in because the front of my 750D blocks all air) my CPU says cool. The slight amount of air that is cut is not enough to cause overheating.

I have a redbone u3 case, the side fan is kind of crappy with the positive pressure.

It doesn't overheat its just that it gets a few degrees hotter than i'm comfortable with i maybe over exaggerated but it is a very fine filter!
