I'm new to overclocking and before I start doing it, I just want to know if my temps at stock settings are fine, here's the picture (did a sensor test via Real Temp) :

temps.gif


BTW my CPU is i7 2600k and the motherboard is a P8P67 pro. Don't the max temps seem high...?

EDIT: I plan to run the rig 24/7, so I think it's ideal to go for 4.5ghz overclocked.
however, while my rig will be on 24/7, it won't be under load (100% CPU usage) all the time, so I will use speedstep.

Idle temps don't matter, load temps are the ones that do.
 
Are you saying that if the temps were "load", it'd be a lot more than 50°C? Eh, this is bad news.
 
Depends what kind of cooling, air or water?
Stress test the system and then look at the temps.
 
I thought the 'Sensor test' from RealTemp stresses the CPU? Because without clicking the sensor test, my max temps were shown as around 30c.

And I'm using the Noctua d-14 cooler...
 
The sensor test does load it, for a second or so, not nearly enough to really tell you what your load temps will be.

Download intel burn test and run that with real temp open. It will give you an idea of what your maximum temperatures really are. After you overclock you should run intel burn test again to make sure that your system is stable. You could also give prime95 a try but ibt tends to produce more heat in less time.
The d-14 is a very capable cooler so you should be fine.

What do you think?

Looks fine so far. How long did you let IBT run before you took the screen capture?
You might want to let it run the entire 5 cycles and then take a look at your temperatures. Regardless, your temps look good. Start overclocking and be sure to run IBT every time you increase your OC to make sure that your system is stable. 5 cycles is not a thorough test, but if your settings are bad it should fail before you get through all 5 cycles.
 
make sure you choose 8 threads as well, otherwise it will do 4 and not fully load the cpu.
 
The Intel's have a maximum safe temp of 100 C, so as long as you keep it under 80-90 C, you should be good.
 
Ok, I did another IBT test with 8 threads and took a screenshot after 10 mins:

lol2.gif


Still okay?

What GHZ should be I aiming at?

At the moment, I'm following this guide:
http://hardforum.com/showthread.php?t=1578110

Since, I intend to run the overclocked CPU for 24/7 use, would 1.415 voltage with x48 multi be still safe? Would that affect the lifespan of the CPU? Would speedstep help too?
I have a feeling that 1.415 volt and x48 would reach more than max temp 70c, hmm...

Thanks in advance.
 
4.8-5GHz for fun and 4.2-4.4GHz for daily use imho.
Of course it'd affect the lifespan,like from 10 years on stock to 6 or 7 years on OC.
 
Ok, I've changed the turbo multi to x45 (4.5ghz is what I want) in BIOS and that's it. Didn't change anything else. Did an IBT test:

99271398.gif


No error, no bsod. I did another IBT test with all of the RAM memory / 8 threads. Smilar temps (one hit 70c). Again, no error or bsod.

Then I did a Prime95 torture test and got BSOD'd (the error code was 101) within a few seconds. Eh, that didn't happen with the IBT...

Anyways, I don't know why these temps seem high for a 4.5ghz oc. I'm not sure why. Maybe I didn't apply the thermal paste properly? I used Noctua's thermal paste and I did what the manual said (apply 4-5mm of thermal paste on the centre) and let the heatsink spread it all around the CPU.
My case is HAF 932 and has 11 cooling fans:
4 120mm intake fans on the side panel
1 140mm exhaust fan in the rear
Two Noctua D-14 fans set as exhaust (throwing air at the rear's exhaust fan too)
3 120mm exhaust fans on the top
1 230mm intake front.

Cable management is alright too (most of the cables are located behind the back wall inside the case.
So I believe airflow/case is not the cause as to why im getting these high temps...
maybe it's the thermal paste or the d14 is not seated properly? how would I know..

First. Do a bios update and make sure its one with the pll override otherwise you'll be stuck on 4.8 on a non intel board. The lower you get your idle temps the higher you can OC.

my mobo is Asus P8P67 Pro. And IDK what you mean by being stuck on 4.8. I'm aiming for 4.5ghz.... Is updating my BIOS really that necessary?

The lower you get your idle temps the higher you can OC.

Relevant how? This doesn't explain why Im getting high temps.
And I said that I'm only aiming for 4.5 ghz...

What high temps? Your temps in my opinion are fine. Now if you were showing me pictures of 95C full load I would say that is high.
 
well, I have seen reports that people get 50 to 65c at 4.8ghz with the same or equalivent (e.g h70). except mine is worse... 4.5ghz at 70c
 
Temperature depends on many factors,including CPU revision/voltage/etc.Not to mention the airflow in your case,the fan you use on the H70.
 
Temps also largely depends on your ambient temperatures. If your room is about 4-5 C warmer than their rooms, that can easily lead to an overall increased load temp of 10, maybe 15 C.
 
But if you can start of with a idle temps of 15 to 20 degrees then you'll be able to reach 5hz with no problems
 
Uhhh... idle temps of 15-20 C is only possible and really low ambient temperatures (like below 10 C) with a regular air cooler. Unless you're living in an icebox... I don't see how that's possible/relevant (normal room temp is 20-25 C).

Also, overclocked idle temperatures do not change much, maybe on the order of 1-2 C. So really, the only way idle temps matter is because the ambient temps matter.

a ice box is sub zero. Room temperatures are 23 degrees. The higher you want to go the better cooling you need.
 
You get my point.

The point you were making is that idle temps matter. It doesn't. Ambient temps and cooling method matter. Sure, idle temperatures are an indicator of how good your cooling is, and what your ambients are, but after they're already set, idle temps are irrelevant. You keep harping back on them for whatever reason I don't understand.
 
I have cleaned the paste and reapplied it (4mm diameter), and reseated the noctua d14 properly. triple checked that it's seated properly. yet, I'm still getting the same temps... 70c at 4.5. this can't be happening... many people that have the same cooler as me hit less than 60c at 4.8.

My case is HAF 932 and has 11 cooling fans:
1 230mm intake front
4 120mm intake fans on the side panel
1 140mm exhaust fan in the rear
Two Noctua D-14 fans set as exhaust (throwing air at the rear's exhaust fan too)
3 120mm exhaust fans on the top

oh, the revision of my 2600k is d2 (according to cpuz)
Cable management is alright too (most of the cables are located behind the back wall inside the case).
So I believe airflow/case is not the cause as to why im getting these high temps...

my room is usually 21c...

what's going on? i have one idea... is it possible that changing the turbo multi alone (without altering anything else, coz that's what I did) causes high temp?

I noticed that when I stress my CPU, my temps are 53c for 30 seconds or so, then rose to 72c easily...
 
While Spooony has some points (and they are starting to border on spam), there are limits to what any piece of hardware will do. Temperatures are not the only limit. At some point the voltages will just be too high for your system to take and something will fry, even if you were to cool them with liquid nitrogen.

Your temperatures look good to me. Keep adjusting settings until you reach 24/7 stability at the speeds you want. Keep in mind that no two CPUs are the same, and it is very difficult to compare results when the hardware isn't the same (different heat sinks, motherboards, cases, fans, etc) and the environment isn't the same (different ambient room temperatures, etc).
 
Sorry my fault partially as I didn't explain it clearly. The best way is to get your start of idle temps as low as possible. Don't need to be that but a bit of love and care you can knock it down. Every degree counts later on.

Did you do the bios pll overvoltage fix?
 
By the way, are you still at 1.415 volts? Because your temps seem pretty normal for that voltage. Try lowering the voltage and then see if your system will start up / run stable under ibt/prime95.


Also, if you wanted to link us the sources you are reading that say you should be getting 60C.

Also, keep in mind that it is not the frequency / GHz that determines temperatures. It is the Core Voltage.
If someone has the exact same setup as you, and the same 4.5GHz, but is able to run at a lower voltage, he will have lower temperatures than you will assuming all else is equal.

lol liquid nitrogen don't work on the Sandy Bridge processors. If it can go far on air it will normally fail on LN2. So don't be silly lol
 
erm, I don't know? all of the BIOS are set to default, except the turbo mutli that I have changed (to x45). is this why I'm getting high temps? I hope so... but I dunno... my idle temp is usually 31c. and load temps (without OC) were 50 something.

Dude, you need to stfu. I'm not telling him to cool with liquid nitrogen. I'm trying to illustrate that temperatures are not the only limit on overclocking.

Any piece of hardware will only go so far no matter the temperature.

OK OK OK!!!!! If you are letting the bios set it's own voltages..... Generally any motherboard bios is going to set the voltages at higher than it actually needs if you have set it to automatically determine voltages.

Download CPU Z. Post a screen shot of it while you are running a stress test. It will show us what your voltages are.

Also, ignore idle temperatures.
 
I'm beginning to get the feeling that the only reason Spooony is in here is to get to 50 posts in order to sell something. Anyways, that's irrelevant.

If your bios voltage is set to auto, that means your motherboard is setting the voltage high to ensure you get your overclock stable. Even if that means overvolting by 0.1 v from where it really needs to be. 0.1 v can mean up to 10-15 C difference in temperature.
 
Ok, here it is:

Shown as 1.304. sometimes it jumps back to 1.294 or something
