Intel i5-3570 Overheating

[hacker286]

I Have a Core i5-3570, Gigabyte B75-D3V Ver1.2 Motherboard, 1600 MHz 4x4GB RAM, ASUS STRIX GTX 960 2GB, Cooler Master Thunder 500W PSU, Corsair SPEC-01 Case, Cooler Master Hyper-103 Air Cooler, 2 Front Intake Fans @1200 RPM, 2 Top@2000 RPM & Back@1800RPM Outtake Fans.
Recently while trying to OC my GPU with MSI Afterburner, I checked my CPU Temp. To my shock it was idling at 50-60°C and on max setting any game it reaches 90+°C.
I’ve removed and applied thermal paste thrice (Arctic Silver). Cooler is perfectly placed.
PC starts with 50°C. CPU temp is varying drastically i.e. Shoots from 55 to 71 to 66 to 82. CPU clocks also vary from 3.5 to 4.1GHz.
CPU has already hit 100°C but PC hasn’t shut. Though after hitting 80+°C I can feel warm air leaving my case.
Kindly help.
Thanks in advance.

If you're sure the cooler is secure, also check what the cooler's fan RPM is. It's specs state 800~2,200 RPM. At those temps the speed should be maxed out and loud.

Max CPU Temp 91°C, MAX Fan Speed 2547 RPM

You have an i5-3570, that's a locked cpu and won't OC by manual means in bios.
You have a B75 mobo, that's a locked bios mobo and won't OC.

Ivy-Bridge cpus will do a 400MHz bump in turbo max speed, and thats all. But that won't affect idle temps. The only way you are getting idle temps affected is if somehow you are bumping the BCLK in order to get OC. BCLK OC is going to create huge jumps in temps once you start going over @103 and that tiny CM Hyper 103 is barely better than a stock cooler to start with and is in no way able to decently cool an i5 at OC levels, nevermind bumped up BCLK.

My advice is to bump the turbo if you are able, cpu vcore won't change at anything less than 4.2GHz on that cpu, but other than that forget about OC totally as you have neither the cpu nor the board nor the cooler capable of such.

Checked my BIOS, i haven't OC my CPU, BCLK is at default 100Hz. The CPU attains 4.2 GHz on its own.
Checked windows resource monitor, BASE CLOCK SPEED IS 3.8 GHz instead of 3.4 GHz

Msi Afterburner can also OC the cpu, not just the gpu. And that's what it's looking like it's done with that increase to the base speed (should only be turbo, not base, base should still be 3.4GHz.). My only guess is that it's also bumped up vcore as well, which is really not needed as Intel set those cpus high to begin with. I'd go back into Afterburner and see if that'll reset the cpu back to defaults, barring that I'd go into bios, F5 to reset to factory optimized default settings. F10 save and exit. Reboot. If it then goes back to the bumped settings, Afterburner is more than likely the culprit.

It's a software OC. So reading bios will always show the pc as is at boot. It's likely that the OC is not applied until after the pc is fully booted, the software starts up, so shows in Windows, but not bios.

Tried factory defaults, CPU Temp in BIOS is 62°C, CPU Voltage is 1.068V and DRAM Voltage is 1.332V

 

[Karadjgne]

That's high. Even running bios at factory defaults it shouldn't be more than @45-50°C unless your ambient temps (pc sitting next to floor heat vent?) are high, even with that cooler.

Ambient Temp is 28-32°C. PC is kept on Desk, next to the monitor.
Tested my CPU with Intel Processor Diagnostic Tool, Everything is waorking perfectly fine.

PLS HELP GUYS

If you pull the side off the pc does that change any temps?

And please have some patience, your last post was 5am my time, ppl do sleep.

 

[clutchc]

That Cooler Master cooler is way more than enough for a non-OC i5-3xxx. It appears there's something wrong with the cooler or the installation. If you still have the original stock cooler, put it back on instead and check temps. (fresh TIM) And be sure you know how to properly install Intel's crappy push-pin cooler.

I tried that, there was around 5-6°C temp drop.

No i don't have the stock intel cooler. And yes my cooler is installed properly. I know how to install a cooler.

Sorry, wasn't trying to insult you. I was just trying to be sure to cover all bases and help. When you said your idle temp was 50 - 60C, was that the range of core temps per core? i.e. what is each core's temp at idle?

All Cores idle at 49-60C

For some reason, your link only sends me to imageshack.com. The home page.
1) what is the CPU usage when at 'idle'?
2) how do you have Win performance set, high performance? If so, drop to balanced and see what happens.

Answers:-
1) CPU Clocks at 3492 MHz at idle, Usage 5%
2) Its on Balanced

FYI I was using Arctic Ceramique 2 Thermal Grease, I applied Arctic Silver 5 and now my cpu temps max reach at 87°C, CPU idles at 40-45°C

Those temps are way higher than they should be (obviously). Something is wrong that is hard to diagnose from afar. Let me ask you this... did you buy the i5-3570 used? Have you been (BCLK) OC'ing it?

 

[Karadjgne]

So the EasyTune6 is not enabled? That's a software OC applied after bios loads, so won't register until you are in windows. It'll automatically set cpu speeds to 4.2GHz by raising the BCLK, somewhat, which affects everything and anything to do with communications on the front side buss, basically the cpu, ram, gpu, hdds, SSDs et. Side affects are periodic instability, bluescreens, and massive rise in temps.

Only way to fix it is fully disable EasyTune6, or better yet, delete it

Yes, its a used one.
No I haven't been OC'ing it.

Also should i just buy Thermal Grizzly Kryonaut. Would that just do the job?

I really don't think it is a thermal paste issue. Besides, there's only a few degrees C difference between the very best TIM and the worst.
I'm wondering since the CPU was used if the previous owner OC'ed it to the point that the cores are nearly fried. Or let it run with dried out TIM at very high temps.

 

[Karadjgne]

Wondering if the TIM under the lid hasn't started drying out and the cpu taken a decent 'whack'. Dried out paste isn't an issue, it's the stuff in the paste that's thermally conductive, not the paste itself, but if a heatsink gets thunked on dried paste, it looses the bond and temps go nuts.

To say Intel did a seriously crappy job with that TIM on those Ivy's is an understatement. There's an 11°C difference between hot and cold cores on my i5-3570k and a 9°C difference on my i7-3770K at idle.

Is op reading hottest core, or average or coldest?

Update your BIOS version to F9. DoubleClick on the mb_bios_ga-b75-d3v_f9.exe file, extract it a a USB flash drive. Reboot your PC, get into BIOS and use Q-flash to update the BIOS.

After the update reset the BIOS by jumper (clrCMOS)

Try a different tool to read the sensors: coretemp

Just to be sure, I know that you know how to place a heatsink, but everybody (me included) can miss a simple thing like:
The foil of the heatsink was removed before installing?
The correct stand offs (plastic washer inserted to the back plate underneath the motherboard) were used to install the cooler?
It´s not overtightened
The cpu fan is connected correctly with its 4 pins to the CPU FAN header of the motherboard?

how will the cmos reset help?
already i have update my bios to version F9.
