AMD FX-8350 Extremely Hot Temperatures

Hi all,

I have a problem with my brand new FX-8350. Before I go on and on, I would like to list my specs:

FX-8350 @ 4.2 (stock)
R9 380x @ 1070/1500 (stock)
Gigabyte 970A-UD3P Mobo
16 Gb Ripjaws @ 1866mhz
PNY CS1311 240 Gb SSD
Seagate 1Tb HDD

andddddd...

Cooler master Geminii S524 ver.2.

Now, I know that this is not the best cooler in the world. If I thought about it a little harder I would have spent the extra $15-$20 on a larger case that would support a Hyper 212 evo. But I didn't. So I'm left with this mess to deal with.

But here's the weird thing: I previously had an FX-6300 @ 4.2GHz that ran fine. I mean it was great. Temps were manageable - not great, but manageable. I could play GTA V maxed out at 50-60 fps with temps never pushing past 65 degrees.

After installing an FX-8350 that I thought would be the greatest thing since sliced bread, I am far from thrilled in terms of its 1) performance in relation its smaller six-core little brother and 2) the damn temps. With the same settings in GTA V, I was getting 75-80 degrees, thermal throttling of course.

Of course I removed and reapplied thermal paste 3 times over with no avail trying to get temps that would not melt my system.

The reason I am reaching out to Tomshardware is because I really do not want to give this chip away. But with the 6300 being effectively better than my eight core "beast," what is the point in even keeping it?

If anyone can help me out, that would be great. Hopefully my spiel wasn't too long and lost the interest of some.

Thanks in advance for any information!!

-Wes

I'm going to build off of what CountMike said - check your voltages. Oftentimes, the amount of voltage used to fuel stock frequencies is far above what is actually needed. If, while stresstesting or gaming, your voltages are going above 1.4, that is far too much for that frequency (unless you really did roll that bad for silicon lottery.)

I have owned two FX-8320s that can run at 4.0ghz with ~1.2 volts. They can run at 4.4-4.5ghz with ~1.35 volts. So if you are running above these voltages to achieve stock frequencies, that's what may be causing you to get ridiculous temperatures.

Long story short, experiment with undervolting.
I think there's something wrong. Gemini S524 isn't bad at all. It should cool the 8350 to about 60-65 degrees @stock.

I know this is very unlikely, but I've seen some defective chips overheating for no reason. The 8350 doesn't run that hot usually, even with a relatively weak aftermarket cooler like that.
 
As refillable said, I have seen some of those processors run hot for no reason but also some MBs insisting on giving too high voltage to CPU.
If you must change processor I would recommend FX6350 BE which could be OCed to 4.7 - 4.8 HGz and give just as good gaming performance as any 8350.
Other options may be 8320e or 8370e which run at lower voltages and cooler.
