AMD 8350 overheating issues

I'm using an AMD FX 8350 eight core processor and it's overheating rather quickly, resulting in my computer shutting down.

This will happen when playing games (specifically Shadow of Mordor, Skyrim, Witcher), but also when rendering animations in Maya and After effects. This is a problem because I can't complete my work with this consistently happening.

Idle temp is about 40 c. While rendering with Maya it quickly jumps to about 80 c after around a minute then will shut down the computer. Rendering the same animation with a lesser processor causes no problems so I don't see why this is happening.

I have to note that this is not the first time I've run into this. I had to return this processor a few months ago because of this specific problem and the replacement worked fine until now. I applied aftermarket thermal paste and dusted whatever I could- no good.
 
Solution


I have a Corsair H80i cooling off my 8350 in my AMD build and it's doing perfectly fine. I do prefer AIO liquid coolers over air coolers since they don't need so much room inside the case right off of the CPU. They have a small block that attaches to the CPU socket and then the bulk of the cooler is the radiator that attaches to a fan's spot on the case. You would only need to figure out what size fan port you have and install the thing and you get...

What cooler do you have on the CPU? Please do not say the stock one. If you do have the stock one on there then you need to get an aftermarket high end air cooler or an all-in-one liquid cooler immediately.

Cpu isn't overclocked. And unfortunately I am using a stock heatsink.

I did buy an aftermarket heatsink but it wouldn't fit my case because it was too tall. Any recommended heatsinks?

EDIT (I got the cooler master hyper 212 evo and it didn't have the proper connection for my socket)

I'll look into a liquid cooling solution. I'm not an expert at this in any way, and I'm guessing since both responses assumed I should be using an aftermarket cooler I should invest in one and try it out. Thanks for the fast response. I'll post back here if it doesn't seem to make a difference.

Sorry, I'm using the sabertooth 990fx, am3+ socket.

hitting 80C isn't possible even on the stock heatsink unless it's either completely clogged with dust, the fan is damaged or capped way too low, the thermal paste is crusted to powder or you don't even have paste in there...

So check the fan speed, it should be very loud when the CPU heats up to 80C (it should actually be capping out at 70C), if it is then check the airflow, if there's heaps of flow then you need to replace the thermal paste.

edit; you mentioned about it being dust-free and having after-market paste, perchance have you put too much paste on? it should only be a thin layer.

I don't think I applied too much thermal paste, and this problem was occuring before I applied the aftermarket paste to try and fix it.

Like I said this exact problem was already happening on this processor and I had to get a warranty replacement. I may try a CMOS reset and see if that makes a difference.

perchance what motherboard and PSU are you using? there could be instability which could cause a higher than ideal core voltage or the VRMs running very aggressively. A lot of the AMD boards have options in the BIOS to control these and it's also possible these may have been modified unintentionally.

I'm using a sabertooth 990fx and an 850w psu from thermaltake. I'm assuming a CMOS reset would solve the issues you mentioned?

I did a CMOS reset and am rendering an animation for 500 frames (essentially like a stress test, as all cores are at 100% load). So far the CPU has been able to go longer than it ever has without overheating and it stabilizes around 72 c and will not go higher. I'm assuming something in the CMOS reset solved the problem, though I will look into a better heatsink.
