i7-6700K Overclock temp

[Trioxide]

Hi,

 

I recently put together my new rig:

i7 6700K + Corsair H110i GTx AIO cooling

Asus Maximus VIII Hero Alpha

Asus Strix R9 390 DCIII OC

 

So, I decided to overclock both and test stability.

The GPU runs stock at 1050(gpu)/6000(vram). I overclocked it with Asus GPU Tweak to 1100/7000 - runs stable, no artifacts and temp was at 84C (Using Asus GPU Tweak temp monitor I got max 83C and Corsair Link 4 said 84C).

The GPU Tweak utility won't let me OC higher than 1100/7000, even if I put in a value manually, it auto adjusts to these 2 settings...

 

The CPU is another story. On stock it runs under load max 47-48C. When I OCed it to 4.6GHz it went to max. 83C (hottest core on AIDA 64 monitor during stress test).

But when I OCed it to 4.8GHz-which was stable at any given time-I wasn't comfortable with the temp. 40min into the stress, AIDA64 showed a peak of 93C (Corsair Link 4 showed 100C for the CPU and 29.5 for the H110i GTx), and that's when I stopped the stress test, because I wasn't comfortable with the temps. Although I have to mention, that AIDA64 thermal throttling (the green line) was at 0% all of the time...

That makes me wonder, are the temp. measurements off in both softwares (since no thermal throttling was shown) or is the H110i simply not enough for this CPU when OCed?

 

I also noticed something strange, I had set, in the bios, CPU vcore to 1.325V - CPU-Z which I had open through the stress test, was showing a switching Core voltage between 1.477V and 1.488V...

When I got back into the bios, the setting was still 1.325V. Was it too low and did it auto adjust, or am I missing something?

 

These were my first overclocks after a long time (I think my last overclock was a E6750 on an Asus Striker Extreme mobo, that was more than 5 years ago...) and I just wanted to see how my new rig fares.

Both overclocks (CPU 4.8 and GPU 1100/7000) finished ASUS Realbench, Cinebench and 3dMark, before I ran the AIDA64 stress test and that's when I saw the temperatures, which were too high for my taste...

If it doesn’t thermal throttle, your fine. If it gets too hot, it will save its self and throttle or shut down for emergency

[Trioxide]

And what about the Core V that went atomatically to 1.488V? Even Linus in says in the OC videos, that you should not exceed a 1.4V...

thats an good qustion, mine have automactily put its self over 1.488v and it seems stable but i am worried of how much you could hold it there, along triocide i also i have the same aio cooler and cpu as you but i'm seeing temps about 80 c on load on a 4.9 overclock

80C on a i7 6700k running 4.9 with a h110i GTx? hmm, gotta check my thermal compound, because that's a huge difference there...

I'm using Arctic MX-4, could be that I didn't apply it properly...

What were your temps at stock speeds, if you remember?

 

[noone394]

it was sitting at about 20 c idile and 65 on load, also what kind of fans are you useing, plus is the fans in a pull , push or both? because im running push pull method noctua NF-a14 FTW  

[odstkiller2]

I personally have the same CPU and cooler I get around 65 C On 4.6 Ghz,  (under full load),

[Trioxide]

That's also a strange value, cause I get 23C idle and about 48C on load on stock.

I'm using the stock fans that came with the H110i , and they're set to push the air through the radiator, out of the case (on top)

[noone394]

you may want to experiment on different cpu compounds and see what works best for you, also how air are moveing though there?

 

[noone394]

some compounds like better idile temps to reach low temps and orthers like hotter temps to cool better, i would do a bit research an bit into cpu compunds it may be worth you while

I got:

- 2x140mm vents on front, pulling the air in (Corsair Obsidian 750D stock vents + High Airflow Intake kit mounted)

- 1x Scythe 120mm on bottom, also pulling air in

- 1x 140mm vent on the back, pulling the air out (also stock from the case)

and the 2 on the AIO cooler pushing the air out on top through the radiator

 

EDIT: I did, I replaced the stock compound with Arctic MX-4, which was tested as a very good one, it also sank the CPU temp for almost 4C on stock settings

Better be careful though when changing thermal compound your cpu might bend #dankmemes

[Trioxide]

Ok instead of editing, I manged to quote my own post and change it while I thought I was editing, this won't be confusing at all...

[noone394]

you could also replace the heat spreader compounder under the plate where the cpu and heatsink touches at but it will void your warranty 

 

[Trioxide]

Thanks for the heads up, although I never heard for a CPU to bend(?) and I did my fair share of PC maintenance vback in the day, when I worked in a computer store, so no worries there, I'm not a total noob

Yeah I saw a lot videos on that, I'm just not sure it's worth doing it, and it carries the risk of damaging your CPU, quite a high one if you ask me...

We thought too much force had been applied to the chip by installing one of those coolers with an electric screwdriver.

That's kind of ridiculous, who in their right mind, would mount a CPU cooler with a electric screwdriver?

[noone394]

well of course odstkiller the plate is so thin that you can but thats why is claims that could bend the plate 

[odstkiller2]

Hence the #dankmemes

[noone394]

but since your cpu cooler is an 240mm or is it an 280mm?

 

[odstkiller2]

280

[odstkiller2]

I think

The H110i GTx is 280mm
