Prime95 Dangerous Temps within Seconds

This is my first build, and i'm new to PC. Any help is appreciated.

This is my build:

Asus p8z77-v pro
i5 3570k
GTX 680 FTW+ 4GB
NZXT Phantom Full Tower (I think the case fans are connected to the PSU since the Motherboard doesn't detect them)
2x4gb Corsair Vengeance RAM
Samsung 830 128gb SSD
WD Caviar Black 1TB
Asus DVD Drive
Corsair 850W Gold PSU


I have everything on Stock. Also using Stock CPU fan.

I just ran Prime95 with my CPU fan running at 100% and had 1 core shoot up to 82 C and one shoot up to 89 C right away. I need some major help. What should i do? What's wrong with my PC :(  ? It can't just be the stock fan right? Even at 100% it shouldn't be running at 82 - 89 C right?

It sounds like the cooler may not be mounted correctly. Check it feels tight and not loose.

I did accidentally get a tiny fingerprint smudge on the stock thermal paste. I didn't think it would be that big of a deal but it looks like i was wrong. Could that actually have been the reason? Could it be something worse, like a faulty CPU?? I really hope not. I'm on it right now by the way.

Anyways, i'm about to buy these:


Arctic Cooling MX-4 AC-MX4 4 gram (g) All-Around Thermal Compound

COOLER MASTER Hyper 212 EVO RR-212E-20PK-R2

Is that good?

The 212 Evo is a good cooler especially for the price, there is little point in getting the thermal paste as the stuff that comes with the 212 is fine. I am not sure the finger print would make that much difference, if the CPU voltage setting in the bios is set to Auto it could be overvolting as well and causing the temps. Try setting the voltage manually to 1.15 and see if it helps.

I just checked the voltage on the CPU and it seems to be around 1.220v. Also my Corsair Vengeance RAM is running at around 1854mhz. Is that normal? Also, when i check AI Suite II it shows my Vcore for the CPU as 0.976v. What should i do?

Anyone? Please i really need help with this.

What are your normal temps when not running prime95? It sounds to me like your HSF isn't sitting squarely on the CPU.

check your BIOS setting and make sure everything is on default and not optimized

Did you build this computer yourself? If so, how do you not know where the case fans are plugged in??? Also, my i5-3570k gets into the high 70's low 80's running prime95 and I am not using stock cooling, so I would assume that the stock coolers temperatures could be fairly high. When I queried about the temps I was receiving I was told that IvyBridge runs a little hotter anyways. It was also recommended to me that if I am still able to perform all the desired tasks on the PC without throttling or apparent damage, then it is best not to worry about the heat, as long as it is within reason.

But as others have stated you may have a problem with the stock cooler, however if the fan is running on it I don't think it is the problem, it looked pretty difficult to muck up installing the stock cooler.

@egilbe Currently stock with CPU stock fan at 100%:

HWMonitor: 34-42C
RealTempGT - 32-40C
CoreTemp - 30-41C
AI Suite II - 32C (CPU fan ~2061 RPM)

Everything in the Asus bios is set on Normal or "Auto"

@Chugot9218 Who said anything about case fans?

I'd say thats fine, mine are around 85c when under heavy load. Could also be your case isn't very well vented.

EDIT: If they go over 90c make sure you stop it!

those temps are fine, but it's interesting that your 1600mhz ram is running at 1854. It shouldn't be unless you are overclocking.
