CPU heating problems - i5 - 3570k Ivybridge

Bobybobp · 25 Sep 2017 at 23:45

Hey guys, I have a few questions about my CPU's temperature when idle and when under load.
The fan I have is an Akasa AK-CC4007EP01 Nero 3 CPU Cooler

Before I overclocked my CPU I was getting temperatures of around 42C when idle and a max of 83C when under load, now that I have overclocked the CPU I am getting around 45C when idle and 87C-92C when under full load for about 25 mins.

Obviously, these temperatures are very high and need to be lowered. Tomorrow I am buying a new case with better airflow and I am going to be cleaning the entire PC to remove any dust and am hoping that this resolves the issue, but does anyone have any obvious tips to get the temperatures down while under load?

Thanks, Sam

Reseat the cooler with decent thermal paste, get a better cooler.

Better cooler and thermal paste. 80+ just for gaming as the load (presuming) is high/very high in current temps. What clock speed and voltage?

Thanks for the quick replies.

Going to be adding some more thermal paste tomorrow, as well as reseating the cooling. I've just updated the BIOS as it actually let me into it for once, and that seems to have already improved the heating. I'll update how the switch over to the new case goes tomorrow and see if there are any changes.

The 80+ was me using Prime95 blend tests.

Overclocked to 4.2GHz and it is at 1.800 voltage, I upped it from 1.600 as I was getting some crashes on games.

I think you've got your voltages mixed up. I am on 4.0 ghz 1.2 volts, i7 3770k

The CPU stock voltage was at 1.8 volts as the CPU came pre-overclocked to 3.8GHz, pretty sure that the higher clock speed you want, the higher voltage your CPU will need? Unless I'm completely wrong, which does happen often haha

Seems like a lot of volts, if i recall correctly my old 3570k used to run 4.5 with about 1.35(ish, cant remember) volts.........

Bobybobp · 26 Sep 2017 at 10:01

Ok, I'll put the volts down some more, see if that improves the situation

That's very high. I have mine overclocked to [email protected] on turbo. Use CPU-Z and see what that says.

Running the 3570k myself with a Cooler Master Hyper 212 EVO 4 on top of it, Have never clocked it yet but at idle it sits at 36->38 degrees and whilst gaming (WoW etc) under 70 only time I've ever seen it anywhere near 80 is when i forgot to clean the cooler/case for ages and everything was clogged up.

As above my de-lidded i5-3570K @ 4.2 GHz would sit below 50 DegC even with a basic 212 EVO cooler in games. Voltage was 1.2v max. Usually set lower.

Bobybobp · 26 Sep 2017 at 10:18

I'm hoping that my mega clean and better case today is going to help with these problems as well haha, I've just put the voltage down to 1.1V and it does seem to improve but prime95 still is easily able to get the CPU into dangerous temperature, near 85 degrees so not really sure what to do apart from this new case, I'll update with how the temperatures are after I've finished. Thanks for the help so far

These chips love delidding especially after all this time the tim would have dried up and be useless. I have mine delidded and running at 4.2 GHZ @ 1.13 V with prime95 it hits approx 60oC

If you think it is the case that is the problem try running with the side off for an hour or so and see what temps are like?

Bobybobp · 26 Sep 2017 at 10:26

Side is already off because of it

Are you reading the CPU Vcore or the VIN1 voltage? My VIN1 is 1.848V

Disco_P · 26 Sep 2017 at 10:45

Don't use prime95?

Just double checked it, definitely the Vcore which I've now set to auto as I got BSOD with the lower voltage, I feel like my CPU is just really hungry haha

I'll try another CPU test, but it still reaches fairly high temperatures when gaming.

Drollic · 26 Sep 2017 at 12:55

1.8 can't be correct. 4.2 should need an absolute max of 1.25v and most will happily do that on stock voltage or comfortably under 1.2v. Things start to ramp up after 4.3 normally.

Bluntwrapped · 26 Sep 2017 at 13:32

Most boards won't let you go above 1.5v without a LN2 setting. 1.35v without delid and good watercooling is too high.

1.8v if accurate, is going to kill it. Restore default settings, and tune multi starting at x42 one at a time until you hit a voltage wall. Don't cut corners, take your time and read up on Ivy overclocking guides if you need a bit more info.
