Hi,

Just got the following setup yesterday:

Q6600 SLACR G0
Asus Maximus Extreme
Crucial Ballistix PC2-9200

Currently running on stock cooler. Temps at idle are around 50c - Load 60c.

Used Artic Silver 5 paste on it and have also tried turning the cooler round the other way but same high temps.

Most reviews i have read have it idling around 40c - 50c on load. I don't think its my case (Coolermaster Stacker CM830) though i have a couple of questions on this as this may be the cause - bad airflow.

at the minute i have the two front fans as inlet, one on the back (at the bottom) as exhaust (this may be a problem but i need my mobo connectors near the top for some of my bits to reach the case) and 3 side fans as inlet as well.

I was unsure whether the stock cooler sucked or blew air so i turned the fan on the side nearest the CPU to take out air and that dropped temps a few degrees.

I also just did a overclock to 3.0Ghz and the temps are up a few degress (as expected) so its leading me to believe its airflow.

Ordered an Artic cooler pro 7 to help cooling but any ideas on air flow?
 
just a quick idea.. did you clean the thermal paste off the bottom of the stock cooler before you added the AS5?

Sure you've got the right application of as5?

As for airflow you need it to be positive ie a couple of fans on the front and a couple on the back somewhere should get decent airflow front to back.

If there is massive differences in the core temps then you may well have an excessively concave cpu and might want to look at lapping it?

What are you using to measure temps also? If its some mobo software then its probably really wrong.
 
Thanks for quick reply.

I cleaned off the default crap they put on the cooler and just used a small rice sized grain of artic 5 to put the cooler on

"As for airflow you need it to be positive ie a couple of fans on the front and a couple on the back somewhere should get decent airflow front to back"

I am certain that the cooling is working front to back but will double check this with a lit cig, try get some smoke passing through

"If there is massive differences in the core temps then you may well have an excessively concave cpu and might want to look at lapping it?"

Core#0 - 60c
Core#1 - 56c
Core#2 - 55c
Core#3 - 52c

This is with the current OC of 3.0Ghz (i just set this up using the CPU Level Up option in the bios to save time and check to see if similar temps are seen)

It may well be excessively concave, which would be annoying...

I'm measuring these temps with Coretemp, speedfan shows the CPU at 64c though my system is only 37c - if airflow was that bad then surely this would be higher too? my previous setup was fine with this airflow though it wasn't quick this high spec.

Sounds like its just the CPU cooler being a bit naff - possibly concave CPU?
 
Just took off overclock, temps are following:

Core#0 - 47c
Core#1 - 42c
Core#2 - 42c
Core#3 - 39c

Think its the CPU needs lapping then....
 
TBH...for the stock cooler that sounds about right to me. If i was you i would buy a after market cooler, like the tuniq tower 120 or something cheaper. Anything is better than the crappy stock cooler and it isn't really good for overclocking either.
 
I've ordered a Arctic Cooling Freezer 7 Pro which should do the job nicely, should come tomorrow

Don't you think the temps should be more even though? its strange there is circa 8-10 degree difference from core#0 to core#3
 
they look ok to me. My core 1 is the hottest core and the rest are abit lower, but not by much. Three of your cores are near enough even. To me they look fine. obviously if you where to lap the CPU then you would get much better temps and you can't expect to have the same temps on all 4 cores, but that Arctic Cooling Freezer 7 Pro should drops the temps nicely.

Will have to look into it.

On crutches at the min so can't exactly pop out to get the sand paper :(

Will see what the Artic cooler does, it might be a case of the stock cooler being more uneven than the CPU and thats causing the problem.

Thanks for the advice though, will update when the Artic is in tomorrow
 
I agree with TheMagic1an on a stock cooler those temps seem about right.

You should see a notable difference with the artic installed, stock coolers are often not up to spec for OC'ing. I have the P182 and both my rear and roof fans are exhaust, also the fan on my heatsink exhausts backwords. I would find a stable overclock and then change the configuration of your fans step by step to see if theres a better setup for them. I lost a couple of degree's messing with my fan controller, i used a notebook to record all I did for reference.

I did lap my heatsink however as its a TRUE and was as flat as a banana. Keep an eye on temps as you clock it and see how it goes mate, good luck.
 
Just installed the Artic Cooler Pro 7, has only knocked a few degrees off it but at least an improvement!

Temps are at the following:

Core#0 - 44c
Core#1 - 38c
Core#2 - 36c
Core#3 - 35c

Should i be worried about Core#0 - it is always 4-5c hotter than any other core and there is always about a 8-10c difference across all 4 cores!?!

As two different heatsinks show this, does this mean the actual processor is the problem and would need to be lapped to get a better reading?

TIMUH! - Thanks for the advice, think i will have to play with the fans though don't think much of a difference will come, maybe i'm wrong though and it will solve all of these problems.

Also, am i being unreasonable about wanting this to be cooler? when thinking about it 35-45c isn't that bad at all...
 
My idle as follows at 3.4ghz:

Coolish Room:

32C
26C
20C
29C

Warmish Room:

39C
33C
26C
32C

I think. I've had upto 14C difference between cores and as you can see, a change in room temperature (that i don't even notice), effects it dramatically. It's luck of the draw sometimes, you have a good chip, or a bad one. Mine also has a very high VID so doesn't overclock as well as others :(
 
Thats ok - sounds fine to me.

But i am running at stock 2.4Ghz speed :(

I feel something is not right - am going to play with my case fans now

Underload it only went up a few degrees for me so thats a lot better :)

The temps are good for idle. It's load temps that are important not idle temps. Try running Prime95 for about 30mins or so and see what the temps get up to.

You might just have a hotter G0 that others, try running coreTemp and see what your VID is. Mines idles at 33c on all 4 cores except core 1 which is about 2c higher than the rest, but i'm currently at stock.

The temp difference wont do any harm, but if your really worried then lapping the CPU should make them even. If you used AS5 then you should wait for the break in period.

Like TIMUH! said change the configuration of your fans and make sure you have good case cooling.

Ok,

I had two fans on the front as induction (not that great though to be honest), 3 side fans as induction (and one exhaust fan at the back.

I then overclocked the CPU to 3.0Ghz using the built in CPU level-up option in my bios, as i ideally want to overclock this processor - who doesnt!?!

Idle temps were around 45-50c.

I then ran Prime95 for JUST two minutes and the load temps were the following:

Core#0 - 69c (peaked at 70!)
Core#1 - 68c
Core#2 - 68c
Core#3 - 66c

Decided to stop because that is excessively high!

VID is 1.2250 - which is the voltage of the CPU right?

I think lapping the CPU will make a difference to the temps though surely without that the processor shouldn't reach those load temps??

Also, on feeling the heatsink on the Artic cooler, the fins are not even hot..

Any more suggestions or am i looking for a quick fix that is not needed? Just seems in all cases that the CPU runs hotter than i really thought it would.
 
Follow Magic1ans advice on running the new version of Prime95 (so its stresses all the cores), and see what your loads temps are on CoreTemp.

My clock is the same as V3g3tto's 3.4ghz (1.43vcore)

Idle temps in a warm study

35c
35c
31c
31c

Differences between the cores is normal, also check that you have seated the heatsink perfectly, I reseated my TRUE and it made a big difference.

Let us know how you get on :)

ok mate something is up that seems very high temps to me. at a 3.0ghz clock I was still on stock voltage settings and load temps below 44c. And the VID of my chip is 1.325. It is the default voltage of your chip.

get a metal ruler and across the bottom of your heatsink to see how flat it is. It may need lapping, which takes time but is not really that hard, I did it for the first time on my TRUE.

Silly question but does the Artic cooler have a fan?

EDIT: Working from home this afternoon so I'll keep F5'ing this thread
 
temps look about right to me, my m8 has a Q6600 and its temps are about the same, we got them down by 7-9C by using some decent thermal paste, idles in the mid-high 40's now. priming takes it up to 70C+ but this is still with the stock cooler can expect much lower :D
 
Thanks Timuh! Much Appreciated - I'm off work for 5 weeks so got plenty of time to tinker :)

If i'm going to lap the HS, i might as well lap the the CPU as well?

I will try that in a bit. Something is definatly up as all other readings in my case are bout 35-40c, just the processor that is running hotter than everything else.

The Artic does have a cooler, its this one:

http://www.overclockers.co.uk/showproduct.php?prodid=HS-017-AR&groupid=701&catid=57&subcat=821

Got the fan so its blowing towards the exhaust. I could take some photos if it will help show how this is setup at the min?

Johnboyjoe - I used a small bit Artic Silver 5 to seat the HS to CPU
 
I'd definately put a metal ruler or credit card against the heatsink to see how flat it is. I did that to my TRUE and didn't even bother fitting it before lapping it there was so much daylight!

Another thing to check is how secure the heatsink is against the motherboard, if it is at all loose that will affect temps a lot.
 
Well well well...

My processor was bent as anything with the middle the highest and the edgest the lowest - all 4 corners!

I lapped that the most - not the most sparkling finish but my arm ached and it was "mostly" copper so thought time to test! My Artic cooler has these flappy pins that go to the motherboard so couldn't do too much with that, did that manually and took some of the edges off, a bit smoother anyway!

Right the results:

Originally, 2.4Ghz idle with Artic cooler:

Core#0 - 44c
Core#1 - 38c
Core#2 - 36c
Core#3 - 35c

Now 3.0Ghz idle with Artic cooler:

Core#0 - 44c
Core#1 - 39c
Core#2 - 37c
Core#3 - 36c

Big Improvement!

Large FFT Prime95 - Max heat was before:

Core#0 - 69c (peaked at 70!)
Core#1 - 68c
Core#2 - 68c
Core#3 - 66c

Now:

Core#0 - 60c
Core#1 - 58c
Core#2 - 57c
Core#3 - 57c

So lapping and reseating the HS really did make that difference though i think it was the lapping that really done it - processor was so out of shape it was shocking.

However, would you still say those temps are acceptable? You get 44c under load (with load do you mean Prime95, benching etc?)
