FX-8350 max temp

Guy Marshall · January 1, 2020

Does anybody know the ACTUAL max temp of the package for an FX 8350? I have read 61C, 62C, 75C... I have just used CPU Burner on my 8350 @ 4.7GHz 1.488V and it reached 79C very quickly and stayed there. Does that mean 80C is the tJMax?

I use HWMonitor and HWiNFO for the CPU package temperature

To me personally using an FX8320 at 4.20GHz i get 50C average under full load. from every thing that i have seen going over 61C seems to be were most people stop and it says 61C is the max it can handle. So you know i'm not messing with you here's a link to AMD's official web site telling specs about the CPU.

As a fellow FX user that's not 100% ready to give it up, how hard are you pushing your CPU? Also if any one responds here as well make sure you take that input as well.

Hi and thank you for your reply! I looked and saw that 61C figure before and others mentioned it. I thought that the fact that it reaches 79C without thermal shutdown would indicate that the max temperature was beyond that? And 61C just seems far too low to me for tJmax!

I run complicated physics calculations involving black holes daily, and do 2160p60 video editing in Davinci Resolve. I also watch 2160p60 videos on YouTube, use handbrake for 4320p videos. Gaming I do now and again but then again it doesn't hit the CPU as hard as it hits the GPU!

Long term use i don't like the temps but i'm going to wait a second to see if some one has something new to add. In the mean time i'll try to do some digging and post better results. The voltage your using is close to the max it'll allow so make sure you keep an eye out on that. If you are using a 970 chip-set, from what i have seen it's okay on some boards but 4.4GHz is the max SAFE speed for that chip-set. heat kills faster. The 970 is lower quality than the 990chip-set and cant handle it as well. FX CPU's can still punch its way out of a paper bag but they run hot and not very efficient. IPC is bad and in my computer room it can even heat it up. The FX CPU's that need the 990chip-set also so you know have speeds that start from 4.4GHz - 5.0GHz which is the FX-9000 series. So keep this in mind.

Over all my input is your running hot and pushing it a tad to far. But like i said before, ill get more info for a better answer and in the mean time keep looking things up and make sure you take every ones input into consideration. Sorry if this is worded poorly. Ask more questions if need be.

I used to run it at over 5.2GHz (can't remember the final speed I stuck to) on a water loop. That since broke and I am back on air (NH-D15) and after 4.8GHz the voltage requirements hit the roof. 4.7 is enough for me

I dread to think what the temperatures hit when the system actually shut off because I booted to the BIOS and it was 82C

I am running it at 1.440 and it seems pretty stable but will have to test fully.

I am still confused as to why it doesn't throttle even at 79C if the max it can handle is 61C... something seems fishy to me! Even their own overdrive with the offset is 70C max, and even then mine doesn't throttle haha

Sorry for the wait. Every thing i have seen like you and i have said, says 61C max on the core and 71C on the socket. If you are going to get that new rig like you said soon then i guess i don't see why AMD's old school CPU can't go out in a blaze of glory. But if you want the CPU for a few more years i would personally tone it down. If you want good clock speeds if it were me, i would stop at 4.5GHz. This opinion is from some one who's a little to scared to push the CPU they have "Which is FX" over what most people say. Also sorry no one ells has responded. I was hoping to debate with people and come out with a good answer to tell you.

PS~ I still like my FX-8320. I have mine at 4.2GHz stable with a 2310MHz north bridge overclock stable with the CPU just at 1.375V and the NB at 1.250.

I'm only bringing this up to see what you think. Some times things like this make my train of thought work better if i deviate slightly.

If you have a good idea of what you want now to "For your CPU" then i hope i helped in some way.

No worries at all, and I think once one person replies, the algorithm pushes the question to the bottom! I will only have this system for 2 months max after today but probably closer to 1 month. It's just too slow for what I am doing tbh xD! I have never touched BCK or NB as I am too nervous, and mine works after extensive stress testing at 4.7GHz 1.440V

Thank you so much for talking to me about this though and it's great to see another FX user! I wish AMD the best going forward as it now brings competition to stop the 9980XE and 10980XE being as ridiculous as they have been!
