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.

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?

average core!

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?

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.

if the CPU is non K (considering BCLK can hardly OC the CPU)
how can the previous owner OC?

By not knowing what he was doing, and foolishly increasing the voltage thinking that's how to OC. I've had to set more than one newbie straight about that here. Besides... I'm running out of other ideas for the OP.

Because software OC by means of OC Genie etc does a lot more on Ivy-Bridge than on later generations. Newer cpus put a halt on BCLK affecting pretty much anything other than the cpu, but with Ivy-Bridge it affected just about everything from ram speeds to hdd transmission speeds to cpu clock speeds. That EZ button started out with generally a bump to 103.7, then a further bump to 105.3, also with corresponding vcore, SA and other voltage/current increases. The net affect was somewhat faster if it was stable but put a tremendous strain on the hardware since it's not really supposed to run at 105%. Because general knowledge puts OC with bigger cooling, ppl were running ivys at @1.4vcore or higher without knowing and as soon as the cpu started giving errors, ditched the whole platform in favor of Haswells or refresh.

World record speeds done with LN2 are not done with just the multiplier, but also combined with uber high BCLK. Standard OC should not be done with BCLK and honestly the mobo vendors should dump software OC, but it's too tasty a money-maker from the uninitiated.

So basically, i should buy a Thermal Grizzly Kryonaut & Corsair H55 AiO Liquid Cooler. :/

I'm actually wondering if there's not an issue with the cooler base. I had a Phanteks cooler once on a client's pc that gave me a fits because the base was warped, meaning it could never sit flat on the cpu. Took me forever to figure that out.

no chance of that, its fitting perfectly!

 

[Karadjgne]

Oh, it might fit perfectly, but if the base and ihs aren't tight together, if there's too much of a gap, you don't get good thermal transfer from the cpu to the cooler. Idle temps ride high and load temps go off the charts.
