AMD FX-8350 4.0Ghz overheating on LIQUID COOLER!

Hello guys

I m really going crazy here.

It has been 2-3 weeks since i bought this computer, i chose the components and the company assembled them for me.

I have put a liquid cooler on purpose on my AMD FX 8350 @4.0Ghz because i knew already those CPU are heating more than intel.
Also i built this rig for video editing (and gaming ofc) so i wanted my CPU to be as cool as a winter breeze!

I downloaded HWmonitor and Core TEmp, under heavy stress (video rendering) HWmonitor shows 78 degrees (celsius) for CPU package while Core Temp shows max of 69-70 degrees for cores.

The questions i have are the following:

1) When i put the CPU in heavy stress(video rendering)i can watch the tempereture start climbing fast, while frequency tops at 100% on all cores, when temperature reaches 69-70 suddeny the frequency drops at around 60-65% of maximum. Is that normal? shouldnt it be working at full clock speed when 100% usage? (if temperature was right that is)
2) Tj max as shown on Core TEmp is 70 degrees, is that for cores or for something else? If the cores work at 69 is it a problem?
3) I see people here that have OC the same CPU to 4,8GHz and the temperatures do not exceed 60 degrees with air coolers, so what is wrong here it shouldnt reach 70-80 degrees with stock clock speed! and with liquid cooler on top! With liquid cooler i should have max stress temperatures of not over 55-60 degrees, is that right?


My specs are:
cpu: AMD FX 8350 4.0Ghz ==> Corsair Hydro series H60 liquid cooler on it
gpu: XFX Radeon HD7870 2gb
mb: ASRock 970 Pro3 R2.0
ram: 2x 4gb Corsair Vengeance @1866
rig: Thermaltake Overseer full tower with 3 big coolers (top-front-bottom)
psu: Corsair TX850M 850W
SSD 120gb samsung EVO series

Please any help of what is going on would be appreciated.

Thanks

1 if it hits the thermal throttling limit that would happen.
2 that is the thermal throttling limit
3 looks like the Cooler install is suspect and needs to be redone.

In that case replacing the thermal paste is the best option. Fx 8350 still runs much cooler than hasswell but that kind of temps even on liquid cooling at stock frequencies are really unusuall. So replace the thermal paste.

every cpu is different and the cooler you have is insufficient for that cpu you need atleast h100i for these things, as for the question about 4,8 every chip is different and not every chip will reach above 4,0ghz, also whats the voltage settings for your cpu

How do u actually know that i need at least H100? everyone i asked said that H60 is ok, not SUPER but pretty much ok. It should not reach 70-80 degrees even with H60.

What do u mean by that? that EVERY chip is unique? We are talking about factory made chips, not human beings.

My voltage goes to max of 1,4V for cpu. I dont know if thats ok i did not mess with that.

because the temps dont show ok to me, every chip you buy will be different because the ar basicly all faulty chips that simply passed the test to operate @ designated mhz, wich means you can get a cpu that will oc all cores to 5ghz or you can get one that wont even oc one core to 4,5 ghz that;s what i mean by every chip is unique (there is a reason they call it silicon lottery you know), and as people stated before make sure your cpu cooler is correctly attached and you could also reapply the thermal paste on it

There are a few things that could be wrong. The company may have not seated the cooler correctly, or applied too much thermal paste. Firstly, I'd advise removing the CPU cooler, cleaning off and reapplying thermal paste (pea method) and reseating the cooler. If no, the cooler could eb faulty - if it's an all-in-one liquid cooler they tend to have their problems.

Also the max temp you should reach is 62C on the core, and 70C on the socket. As for the frequency dropping when you reach above 70C it's probably thermal throttling.

Worst case scenario is a faulty chip, doubt it though.

Your reply is very good i will go with that.
But if the cooler is not seated correctly or if there is too much thermal paste or even if the cooler is faulty, wouldnt it affect the temperature across all scales? why only at high stress? why all other times the cooler works properly and then during heavy stress it loses it? And why does it stop at 70 or even 75 degrees and doesnt go more?

there isn't as much heat to be dissipated when its not running hard, so it doesn't get as hot. It stops at 70 or 75 b/c the computer starts slowing itself downt to keep from burning up, at a certain temp it will actually turn off to avoid frying itself.

For nearly 4 weeks now (since i bought this rig) i work and play games with these temperatures and not even once i had any shut down or any performance issues.

It will shut down far after you get the performance hit. It's possible that the problem was there at the beginning but has gotten worse over time.

additionally its very possible the pump could be failing and those things tend to get worse slowly and then suddenly once they can't keep up easily become noticable very quickly.

The CPU lowers its clocks when it hits a high enough temperature; usually 80C if I recall right. This reduces temperatures since the CPU is doing less work. So the CPU never hits auto-shutdown (100C I think), but you lose a LOT of performance since the CPU will be so heavily downclocked.

Fact is, something is wrong with your cooling setup. Period.

That is an AMD rig it shuts off well before 100C. Don't fully remember the right number but I know intel allows their chips to run much warmer than AMD. (not an intel vs amd discussion just pointing out that it won't go anywhere near 100)

Just to be sure guys before i go to the assembly company and kick their ass,
is there ANY chance this is because:
1) The cpu voltage needs tuning
2) It has been like 4-5 days since i unparked all cores (but i have searched thoroughly that unparking does not cause overheating in any way)

Thanks for the reply

The unparking can cause issues if the software you used to do it is goofed up, there is no need to do that to a modern cpu. The voltage could need tuning but I don't see why as its a 4 ghz processor out of the box and running at that speed now.

Speaking of that, it has been the last 4 days that i did the unparking that i have a strange small problem.
Sometimes when i restart the computer, it shuts down instead and then when i try to turn it on its failing to start (i press the ON button, the rig starts working i can hear/see all the fans and the lights but the screen remains black, it doesnt even reach the point that boots on windows, i dont have the chance to enter BIOS)

Could that be because of the unparking or is it because of the temperature overload and how can i possibly fix that?

Try reverting the core unparking first. You shouldn't even need to do it on a piledriver (x3xx) processor.

The thing is that i dont know how to revert the unparking.
I searched the registry for this 0cc5b647-c1df-4637-891a-dec35c318583 and then changed some values 2-3 times resulting in unparking all cores.
I really dont know how to revert the process..

Ok this is very serious

According to all the information i gave you on my first post,
is there any possible way that in this 4 weeks time of editing videos and playing heavy games (i only noticed the overheating during the 4th week) that the processor got damaged and will never have the capabilites it should have if it was brand new?
I am sure i think i noticed less fps in games and some frame flaws in the last exported edited video i did the last week.
I am very very scared that the processor got damaged, but if that is the case then the assembly company should replace it with a new one i guess.

Please reply on this, i really dont know if this is possible to happen or not, i dont have that knowledge.

If i am to change the board i have now due to overheating issues,
which one would be good for that chip and not heating up too much as well as be 100% with RAM/etc.

- ASUS M5A97 R2.0 (81.87€)
- GIGABYTE 990XA-UD3 (93.90€)
- MSI 990FXA-GD65 (117.98€)
- GIGABYTE GA-990FXA-UD3 (131.75€) (i can barely afford this one)

IMPORTANT
I DO NOT plan to overclock any time soon, only thing i need is to run a full stress test for 1 hour and have stable temperature and stable max stock clock speed. (no throttling)

cpu: AMD FX 8350 4.0Ghz ==> Corsair Hydro series H60 liquid cooler on it

Guys hold your horses

I know that something has to do with the cooler apparently, but the thing is that i REPLACED the cooler with the stock air cooler just to see what the temperature would be and it is exactly the same, above 70-80 degrees..
I know that the stock cooler does not cut it, but going over 80 degrees? no way sir, something has to do with the board too.
I ve been told that this particular board may have problems with the voltage/phases/heat dissipation/etc.
In fact i have touched the current board during stress test and its burning like hell around the cpu.

Also i would like to mention that in BIOS it states idle temperature 70! degrees while the temperature monitors in windows (HWmonitor and Core Temp) show 20 degrees..

So something has to do with the board too.

Just give me your opinions on the board options i gave you.

Just for reference I had an H60 and the 8350 on stock that runs almost identical to you at full load (70c). I think the H60 just doesn't cut it for 8350.

I changed to H100i and I don't have anymore heat problems. 45c at 4.5ghz

Guy, seriously... how many more of us are going to have to tell you to replace the cooler? Yes 70-80 is hot, especially with a liquid cooler, but replacing the board before replacing the cooler is just not smart. Take it one step at a time and replace the cooler. In fact, just get way more cooler than you need so you'll never suspect the cooler again. Then (this will not happen) if the thing keeps running at these temps, replace the board.

Finally, what is the ambient temp? You don't have this thing sitting in front of a heater vent or something, yes?

Hi guys.
I have the exact same problem, i have the same motherboard and cpu like the topic starter.
I was getting really despaired by this. The cpu was getting down to 1399 MHZ after reaching 65c on heavy games or a simple video encoding with divX converter.

With stock cooler, temps was getting to 79c with a video encoding. Then it was dropping from 4.0 ghz to 1.3ghz.
I putted a new cpu cooler, Coolmaster Hyper 412S. The temps was a bit better, but after reaching 65c the frequency dropped to 1399 mhz again.


Today i putted a small 80mm fan behind the motherboard, to hit with air the cpu socket.
My pc is running stable now on 1 video encoding that i tried and also HeavyLoad program running for 15 minutes. Temps with the video encoding reached 62c without any frequency drop.
Temps with Heavyload reached 63c, frequency only dropped from time to time at 3400mhz for 1-2 sec and then back to 4000mhz.

I think its the motherboard fault or cpu.
What do you guys think?

The H60 is a toy. I wouldn't use anything less than a 120 mm closed loop set up. I rather use a high end Noctua actually.

That board has 4+1 phase power. It isn't going to cut it. It is struggling to supply the juice for that 8 core cpu. There is a reason that board is only $59. You may end up blowing your vrm's and taking your 8350 with it.

Use Corsair H100i if you have the budget or H80i will also work fine.
