Check my system - whats wrong?

[nugga]

Hello, i just installed my new Noctua NH-U12P CPU Cooler. But i'm having some problems. I'm using a core i7 920 CPU, overclocked to 2.80 ghz lol.

I'm using OCCT to do a test a Speed fan to check CPU temp. My core i7 920 temp is about 60 degrees cecius after 5 min, which is all too much.

I can't understand why this happens, becuase my cooler seems to be installed all right, even though it's my first Cooler installation.

Another wierd thing is how the temp changes. For example when i stop a 100% test of my CPU, the CPU temp is falling instantly to 40 degrees celcius. 20 degrees instantly sounds very wierd to me.

 

Maybe there is something wrong with the Thermometer in my Mobo? Or maybe i did some wrong BIOS options?

If you wanna know i used about a 5mm thick ball of thermal compound at the CPU, i guess that's enough?

 

 

And then another question, i set the CPU warning options in BIOS to 60 degrees. Does this make my system to shutdown at 60 degrees?

 

 

Thanks for the help

1: Are all the temps in the in real temp the same? I.E. core0 ** core1 ** core2 ** core3 **

2: have you tried reseating it and spreading the Tim before you sandwich it.

3: what kind of case and are your case and proc fans going to full after a certain temp?

 

I am not sure if this is an issue or not but the temp drops imidiatly that means to me that the sink is working as its disigned and the heat is being cycled out of the processor as soon as there is no more heat being built. that tells me right there that the heatsink is operating properly. if it were to hang around for a long time at 60c after its at idle then I would worry. Try using less tim and spreading it around the chip before putting the HSF on I would say.

 

Im not sure about the last question. last mobo that had a warning per core temp would have an option for shut-down temp.

NOOOO!!! Remove thermal paste! You probably put too much! The layer must be AS THIN AS POSSIBLE!! And make sure you spread it well all around using a piece of plastic bag like I did. That is the best way. Just wrap the plastic on your finger until it's super smooth and then gently spread the thermal paste. You only need a ball the size of a grain of rice on the cpu which you spread.

 

Each mobo has different settings and for each mobo the way it reacts when it reaches a certain temperature is different. It my shutdown, it may warn you I dunno.

 

So fix your thermal paste and while your at it, make sure you put on the cooler 100% correctly.

 

As for the bios I'm not sure if you did something wrong since I don't know your bios. You might want to check the voltage though and see if u didn't juice it too much. Read some guides about overclocking. I'm not a fan of intel so I can't suggest any. You could also revert all the settings back to default and then run stress test and see if you get the same reaction from the CPU. Doesn't have to with the same degrees but rather it reacting the same way meaning after 5 min it would go up to high temps and then after the test back to low temps super fast. That will most certainly tell you if it's the OC or a hardware problem.

I'll try to fix my thermal compund and then post my results again.

then i'm gonna have a look at the BIOS, i might have set something wrong.

Is there any chance that the temp's are wrong?

[nugga]

Okay i did what you told me, and tried to test my system again.

What happens this time is that the CPU is about 50 degrees warm at 100%

But my cores is still 60 degrees warm.

Does it matter that my cores are so warm?

[OwinC]

What is the temperature in that room.

My temps do run a little high. But mine is from my room being so warm 77f.

Plus I need to clean my cooler.

My room is pretty cool about 25 degrees celcius.

Maybe you should make some screen shots of your system as it is now. Use CPU-Z mainly and make a photo of that with a program for taking photos. That way we will k now how you've set your stuff. Open CPU-Z 2 times and put them one next to the other. Then make sure that one of the instances is on the main page as it is and the other is on the memory tab as those are the 2 most important. At the same time open core temp and include that into the photo.

So here i am back again.

I did what you told med Ballist, so here is my result.

 

Idle Temp and info

Load temp and info

 

Here is a few pictures showing the thermal compound on my cpu and heatsink. The pictures is not in a good quality, but maybe you can tell me if you putted too much or too little thermal compound on the CPU

[sack_patrol]

Those images are a little blurry, but just make sure that the whole cpu surface is covered in a thin layer of thermal paste and that would do the trick.

 

As for the overclock. You might want someone with more knowledge of it but I'll try and help. First of all why does your multiplier and voltage change when you stress the cpu? Does it do it automatically? Cuz then I think that that's bad. It might something like AMD's Cool n Quite which isn't very good for overclocking though I don't know what that might be in intel's case. Maybe you could try lowering the voltage a bit more. See how low it can go before it starts crashing. When it crashes increase by 1 and that will be it. You want to have as little voltage as possible. Access volts make it hot.

[wevsspot]

Those temps may be right in line with where they should be dependent on the ambient air temp in the room. Some of the i7 920's run a little warm anyway, plus don't forget that you've got four cores working on the piece of silicon. One core will always run a little warmer than the others so there isn't any reason to worry about that either.

 

Are you using the cpu heatsink fans at full 12V or did you throttle them down using the LNA or ULNA resistors?

 

Regarding the overclocking question - the OP appears to be using Intel Speed Step/C1E/EIST settings in the BIOS because his cpu multiplier and vcore are both reducing at idle. The Intel power saving/heat reducing technologies have worked excellent going back to the socket 775 days (can also say the same for AMD since AM2). There isn't any reason not to use those features except during initial overclocking or extreme overclocking.

 

It's hard to tell from the cpu pictures how well the TIM has been applied or what thickness it is. One method of applying the paste has already been mentioned (rice grain size in the middle - then spread out using your finger placed inside of a plastic baggy).

 

Another method is to put a small dab of TIM (rice grain to bb size drop on the IHS) and then spread it out with a razor blade or credit card edge - this is the method I use on cpus with larger IHS.

 

You can also check the flatness of the cpu IHS and cpu cooler contact surface using a metal engineer's ruler to make sure both surfaces are flat. If they aren't you may need to lap one or the other.

 

When you're all done the best thing to do is apply the new layer of TIM and then do a test fit. Once you have installed the cpu heatsink, remove it and check the quality of contact between the heatsink and cpu. The TIM should be evenly dispersed across the top of the cpu IHS without any bare spots or indicators of high or low ridges/valleys between the two contact surfaces.

As Wevsspot has stated, the i7's run very hot and your temps look very normal. Anything under 70c load core temp is fine.

 

The i7 DO's, if you have a good one, can run very well with minimal voltage. I presume you have you cpu voltage set to auto in the Bios, if so

you can manually set it and probably lower your vcore, hence lowering your temps.

 

As for the cpu vs core temperatures, there is no sensor in the cpu that can accurately display you cpu temp so your best bet to monitor your temps is by using the core temps.

 

Anyway, you are in good shape whatever you decide.
