This applys for PC gaming purposes!

What is the issue?
- My CPU temperature goes above 80celcius (Load) then shuts the PC down at about 85c

Did you clean out debris and dust?
- Yes

Did you put new thermal paste on the CPU Heatsink/Fan?
-Yes, cleaned with Iso alcohol then applied properly (Re-applied it about 5 times now to make sure)

Did you upgrade your BIOS?
- Yes

Proper ventilation and/or turned up fan speeds in case and on CPU fan?
- Yes. Bought new exhaust and intake fans (Case blowing cold air)
- Yes (CPU fan maxes out at about 3300rpms)

Is your GPU running hot?
- No it is running very cool actually

Do you Overlock?
- I overclock NOTHING

Running stock CPU cooler?
- Yes, I don't see why I should have to buy an aftermarket (Not like my PC is all that insane)

I've tried everything guys, even talked to a technician at a local PC shop on the phone for some troubleshooting tips but I can't seem to figure out why it's doing this. Even if it doesn't get hot enough to shut the PC down, it will get so hot that it drop Frame Rate in games I play because it's trying to keep itself cool I guess. I just upgraded my PSU, GPU and RAM but I don't think those are relevant because I even tried to swap my old GPU in to see if the CPU would overheat and it still overheated. I can't see the RAM or PSU being an issue as the voltage is fine.

I've troubleshooted this for about 5 days straight (After work until bed) literally and I'm at the point of just buying a new Motherboard and CPU so I don't even have to think about this anymore.

PC Specs:
- AMD FX-series 4200 Quad Core 3.30GHZ
- EVGA GeForce 750 Superclocked 1GB (No external power source, plugs direct to MB)
- 8GB RAM DDR3 1333mhz
- Corsair CX500w Power Supply
- Nice big case with solid ventilation (Ibuypower ARC 647 case)

Only idea I have left is maybe buying a new CPU cooler? Is my setup just not properly working together? Please help guys! I'm at the end of the rope here!

Your idle voltage should be around 0.92v and working voltage @1.2v. With the offset at '-' it should stay somewhat around that. If the offset is '+' it'll get somewhat higher but shouldn't be 1.4+ at stock speeds, that's OC range voltages and will require a better cooler than the stock unit. The cpu voltage settings are there, somewhere, you need to find them.

No, I'm assuming it has happened for a long time and I didn't know about it because I didn't really game much on my PC due to the fact the previous GPU was very poor. The technician over the phone recommended I update the BIOS which I did successfully. Didn't make a difference in the situation.

So basically when I started to monitor my systems hardware temps is after my new upgrades therefore I found out then that my CPU temp is high under load and even idling.

The reason I started to monitor the temps is because I didn't know why my FPS in-game was dropping so often. Due to overheating.

I currently used 2 different monitoring programs and also checked my CPU processor temp in the BIOS and it was super high even at start up. Like 64c or something.

Yea, my last hope might be a new cooler.. Forgot to mention.. when I opened the side of my case, I put a huge room fan in there to see if the temps would stabilize and I stabilized the CPU temp at about 71-71 degress C... Still very high though 🙁

As I stated above. I did that after I upgraded. Leading me to where I am now.

Thank you for the response.
I did actually use Malware bytes and did a scan a couple days ago, I also have only hit 93% usage on my CPU when in the game only. Not sure if that's too high for just doing one thing or not (Gaming). I don't see anything suspicious when viewing through the process explorer. Hmmm I'm still at a loss.

Make sure the cooler is not lose. Also check the voltage the mobo feeds to the cpu. You may reduce it. Automatic voltage may be higher then needed to run cpu stably and contributes to heat, though it may not be the cause of the abnormality.

Well, looking at CPU-Z. When my computer is idle my Core Voltage is all over the place. 0.936V - 1.2V .. And when Im in-game, its at like 1.2V - 1.4V

I don't know much about the voltage etc but is it suppose to be going up and down like that? And is it suppose to hit 1.4V? Seems high...

I searched the BIOS for like 15 minutes on how to change the VCORE or CPU voltage and I can't find a direct spot to just change it.. Any ideas for me ?

Asus motherboard by the way.

Yes your voltage will go up and down along with the speed your cpu is operating at. If you overclock and manually set and lock the voltage it will remain constant. I used to have an fx 8350 with an asus sabertooth MB. Without overclocking and all the voltage set to the stock auto mine would ramp up to 1.41v but it also idled around .9 something volts.

To change the voltage you need to go into the bios, change your voltage setting to manual and then adjust your vcore. I'm not sure that is your issue since the temp at idle is still high and the voltage is only.936v. yyk71200 mentioned to check the cooler to make sure it is not loose. if you search there is people who have issues with not having the cooler tight enough on the cpu even though it flattened out the paste.

Yeah that's exactly how mine is running.

So voltage is good? Now what... Lol feels like I have to buy an aftermarket CPU cooler? I don't mind doing that but I don't want to just spend money to get no where. Yeah trust me the CPU heatsink/fan is on tight right now, like I said before.. I've re-adjusted, cleaned and re-applied thermal paste about 5 times now to make sure. And looked up different "Techniques" for applying the paste.

The computer tech I talked to he said its possible the motherboard could be the issue. I said maybe a sensor or something is not functioning properly causing unstable temps in my processor. Those are his words though. I feel like if I get a new CPU cooler/New Thermal Paste and if the temp is still high. I should just start with buying a new MB 🙁

Yeah the sensor also could be faulty, from what i've read it's not very common but who knows. You could get by with undervolting since your chip is a 4 core and doesn't require the same voltage as my 8350 did. Plus the 8350 runs at 4ghz stock, but that chip still shouldn't be running that hot at idle. If you aren't comfortable with setting voltage then don't but there are lots of videos out there to watch. Other than that i guess you could feel the cooler by hand when the processor is running but that would be just to verify the cooler is dissipating heat.

What motherboard? What ram exactly?

My Asus bios has an AI Tweaker in Advanced mode. On that page will be all the relevant voltage settings like cpu voltage which should be in offset, and under that is the cpu offset mode sign which should be ' - ' not '+'. Cpu offset voltage should be auto. Yours may be different but shouldn't be that much different.

Yes it is enabled

Oh my god dude I think I'm on to something now!!

Just clarify that this was ok for me to do. I went into BIOS, under the advanced settings the only thing I could really find that was anything to do with adjusting my CPU voltage was "Cpu overvoltage" So i just set that to 1.20000 and I noticed in my HW monitor that when I was doing things on the desktop is was between 0.9v-1.3v (CPU) ... And when I tried to play the game it was very steady at 1.2v (CPU VCORE) instead of being all over the place like before. So playing for a full 10 minutes my CPU temp didnt exceed 68c!! Which is much nicer then 80+ like before. Im assuming that the "overvoltage" is my actual voltage setting for the CPU? I just want to make sure that was okay to adjust because so far it seems good. But my question is... Should I lower it slightly to attempt lower temps? If so, is this going to cause issues with stability?

You can lower voltages little by little until you encounter instability under the load. Prime95 is a good tool to test stability. Test each time you lower voltages maybe for half an hour to an hour. When test fails, bump voltages a notch and leave them there. Monitor your temperatures while testing.
