CPU Overheating because of GPU , what to do?

rafovafo · Sep 21, 2017

I recently got a GTX 1060 6GB. I've done some research and determined that an FX 6300 is enough for it , and so it was , but it started overheating , probably because of the GPU. I have a stock cooler , so I am guessing thats the problem but I will need help from anyone to find a solution , should I get a new cooler or wait a year so I can afford a new cpu?
Mobo : ASRock 980DE3/US3S
SPU : 600 W
Current GPU : Radeon R9 380
Memory Type : DDR3 8 GB

How did you determine that it overheats? AMD Overdrive shows 0°C or lower thermal margins? Your ASRock 980DE3/US3S requires a top-down style CPU cooler (like the stock cooler) to prevent the VRM from overheating.

Well I didn't determine that it overheats but I am pretty sure. With just starting up the PC the temperatures of the CPU were 70 C. It got up to 80 no problem when playing pubg. Do you think that its not the case of overheating? If so please tell me a possible cause.

RCFProd · Sep 21, 2017

80 degrees is far too high, but I don't think the GPU is the cause.

Have you monitored GPU temps aswell?

rafovafo · Sep 21, 2017

Yes the GPU temps werent higher than 60 , 65

rafovafo · Sep 21, 2017

And with it's fans it went to 40

rafovafo :

You can't accurately measure FX CPU temperatures; what are the thermal margins? They should be high at idle and lower at load, but ideally they still should be 10°C or higher. The CPU throttles when they get close to 0°C.

GhislainG :

They don't go over 10. Also yesterday I swapped to GTX 1060 which is too powerful then went back to AMD and noticed that FPS in games dropped and the temperature today is much higher but I don't know why. The CPU temperature right now is from 60 - 70.

GhislainG · Sep 21, 2017

You mean the thermal margins never exceed 10°C at idle and they are negative at full load? As soon as the CPU throttles (or the VRM causes it to throttle because it's too hot), its frequency drops to 1.4 GHz and that causes FPS drops. You can't accurately measure that CPU temperature; therefore what you see is not useful. Post the AMD Overdrive screen while stress testing the CPU once it throttles (frequency dropped to 1.4 GHz).

GhislainG :

They never above 10 with the gtx

GhislainG · Sep 21, 2017

How low do they get?

rafovafo · Sep 22, 2017

They go from -10 to 10. I really dont have the lust to swap my gpus right now.

madmatt30 · Sep 22, 2017

-10 is wildly overheating mate , thermal margins work backwards - the higher the better.

The normal thermal margin at idle word be 30-40c , under load 10c.

Anything below 10c is approaching the thermal limit
0c is the thermal limit
Below 0c is overheating.

This has nothing to do with the GPU at all, you need to check your cooler fitting

rafovafo · Sep 22, 2017

How come? With my radeon r9 380 the margins are super high. With the gtx its incredibly low. I want to get a hyper 212 evo.Will it fit? Also I have to put thermal paste .Will that also help?

RCFProd · Sep 22, 2017

You could clean your CPU cooler, re-apply thermal paste and reseat it properly before deciding to invest in a new CPU Cooler.

Also, fit depends on the width of your case, we don't know which one you use.

GhislainG · Sep 22, 2017

rafovafo :

The 212 Evo won't cool the VRM (you can't ignore ASRock's note); therefore it will throttle the CPU. What's the difference between the R9 380 and the GTX 1060? Does the R9 380 exhaust hot air outside of the case while the GTX 1060 doesn't? If so, then the solution is to improve airflow through your case, not to replace the CPU cooler.

rafovafo · Sep 22, 2017

Isnt the GTX 1060 6GB overwhelming for my FX? Or can I run the GTX no matter what processor? I know the FX will bottleneck the GTX but does it mean it will overheat?

rafovafo · Sep 22, 2017

If I can run the GTX I probably shouldn't OC my FX right?

madmatt30 · Sep 22, 2017

Running a 1060 vs a 380 should not affect CPU temps , you may get a bit more usage from the CPU with the 1060 because it allows it to spread its wings a bit.
Not to the point it's overheating though.

rafovafo · Sep 22, 2017

Then what do I do?

GhislainG · Sep 22, 2017

Post a link to both GPUs. Does the CPU overheat if you stress test it with Prime95 Small FFTs for a few minutes? What is your ambient temperature?

rafovafo · Sep 22, 2017

Ill link the gpus as soon as I get on my PC. I really dont have the lust to swap gpus right now. The idle temp was 60 to 70

GhislainG · Sep 22, 2017

Temps are not accurate; you need to check the thermal margins.

rafovafo · Sep 22, 2017

As I said the thermal margins were from -10 to 10 .

Ill do the stress test sunday or tomorrow.
