Performance crippled, possible CPU overheating issue?

Hi guys,

Long time lurker, first time I've needed help.

I've recently been having performance issues on my computer, starting when I was playing Rocket League. For the past week, my computer has been unable to play at decent framerates or load anything quickly. For reference, my computer is made up of:

MSI G45-GAMING motherboard
i5-4690k overclocked to 3.8GHz from 3.4
Hyper 212 EVO
EVGA GTX 770 SC
Samsung 840 EVO 250 GB
WD Blue 1TB
8 GB Corsair vengeance, 8 GB G skill Hyper X
TP link network card

I recently downloaded Open Hardware Monitor to see if it might be a temperature issue, and as it turns out I have overheating issues. I just went out and bought thermal paste from Best Buy so I could clean and reseat my CPU cooler, but that did not solve my problem. I am still seeing over 100 degree temperatures, but just in the CPU #4 reading. Does anyone have any idea what's going on or any good possible solutions?

Screenshot I took before shutting it down ASAP: http://i.imgur.com/lnTXhtr.jpg?1

Let me know if there's any more information that could help. Thanks!

After a bit of searching, it has to be one of 2 things, the software is bugged and not displaying the correct temperatures, the sensors are bugged. Your cpu core temp is fine. From other threads about that specific sensor, it seems to display whatever the hell it wants to, but, the mobo will throttle the cpu based on those temp readings.

I think the thermal sensor(s) is bad.
 
What are the temperature readings in the BIOS? I personally prefer Speedfan over HWmonitor.

If the temps are indeed correct, then immediately reset your BIOS to factory defaults to prevent further damaging your cpu.

400 mhz is a small OC, did you increase voltage? Or is it still left on Auto?

List your PSU, most important part when OCing.

Did you prime95/IBT to stress and check stability of your cpu as you overclock? How long and what were the readings?

What He said. You could try setting the CPU back to stock and test it, but I reckon your Mobo temp sensor has gone.

Thanks so much for your reply! I'm actually on Google myself right now going through "can one CPU core go bad?" I will definitely look up the thermal sensor. Question though, is the sensor part of the CPU itself or the motherboard?

Thanks again!

EDIT: sorry, to add to this, I've noticed most people who have this problem are experiencing shutdowns. My computer is just slowing down. Is this still within the category of failed temp sensor?

It's on the motherboard. Your MoBo is throttling the CPU but not shutting it off. Could be the same thing.
 


Just entertain yourself and check temps in BIOS, it won't take all but a minute

update you know how to tell if your temp sensor is bad, or if it's an OC job gone bad? Reset your BIOS and test for temp again.

Its a motherboard sensor, and literally no one knows what temperatures its even reading, some of the post ive found have that censor displaying a negative value, than a massive positive value on the next sensor.

I would have to believe an RMA is in order, or atleast contact MSI about the issue, there are pretty much zero chance of damage unless your the sensor is reading VRM temps, which should not be anywhere close to that at idle, unless your overclock voltages are super high, but your cpu would probably be fried by now if that were the case.

I did not change the voltage. My goal was to get the fastest speed I could on stock, since I'm only using the 212 EVO. As for PSU, it's the Seasonic 760 80+ platinum, which I heard great things about.

My BIOS is reading 44C for the CPU and 22C for the system. That seems a little higher than my normal temps, but WAY less than the 110 hardware monitor is giving me. Any idea how to check the CPU 1,2,3,4 through bios? I'm just seeing the 1 number for CPU.
 
Seasonic is excellent, you're good :p

I don't think you can check for individual core temps in BIOS if its not already there. However, it does give indications that HWmonitor is defective, which has been in my case. That's why I use SpeedFan.

I'm gonna try speedfan right now, thank you!

Update: Speedfan says 128C for the CPU :(

It also says AUXTIN1 is the same!
 
I am sorry. Either he is right about your mobo temp sensor or it is actually overheating.

However, cpus are designed to shut down after reaching a specific temp. i5s are probably at 100c. It would be odd if it is still running after 120.

If you want in investigate, try reset BIOS to default settings and re-check temp.
