After trying to lap my q6600 and making a botch job of it..

I sent off my q6600 G0 to get it professionally lapped, and it comes back perfectly mirror finished.. I plug in the cpu and add my Silent knight II hsf on top, with a tad bit of artic silver 5 in between, start up the pc, and enter the Bios.. I watch for 10 minutes 33c max in Bios.. So following that, I oc the Q6600 to 9 x 1333 to reach 3ghz, open up windows, load up coretemp and it's showing 50 - 55c idle! I loaded up a game, Grid, and it was hitting 72c so I turned the computer off..

I'm using an Asus P5N-T DELUXE MOTHERBOARD

I opened up the case, and gripped the Hsf to see if it was loose, fairly loose yeah, it isn't tight enough, its moving left to right, like slipping whenever i give the hsf a little tug.. The problem is I can't put any more pressure on the cpu because the silent knight II has a very simple locking mechanism and theres not much one can do with it.

55c Idle WAAAAAAAAAAAAAAAA

Why the hell did I get it lapped? I'm regretting it now.
 
I've just had a look at some pics of your heatsink and it's fittings.

Is it posible to cut/file down all the plastic sleeves that the bolts pass through by a few mm so that you can tighten the HS to the CPU more securley?

If you could, it would enable the heatsink to be pulled down onto the heatsink more - ensuring a more secure fit. If it's a similar fit to the pic below it should be pretty straight forward to do.

I have no idea whether this is possible but if the sleeves are plastic - and are easy to cut/file this may be a way of getting more tension onto the cpu.

Hi, I have just tried pushing down on the cpu by applying pressure on top of the hsf, but it is still swaying side to side, its not that its vertially loose, but theres a slight gap on the sides between the heatsink and the cpu cover, so it doesn't fit snugly.

I've just dropped the cpu down to auto speeds and it's still showing as 55c idle :(
 
That means it's not fitting properly - and wont until you've b*stardised the fitting to accomodate the lapped cpu.

Is it possible to do what i suggested? If it is - it should be a straight forward fix.

Looks possible mate, yeah. I'll give it a go. Thanks.

Hey fluidz,

I'm just reading through this thread looking for mention of the processor VID and vCore setting, at a guess I am thinking you have the processor voltage on [auto] which will almost certainly be over-volting the chip and causing it to run hotter! :)

If you check the processor VID using Coretemp you will be able to see if its a Low VID/Hot running or a High VID/Cool running chip, If you have a Low Vid chip running *overclocked* on [Auto] vCore then you will have a small furnace situation heh! :p

The last thing to mention is about case cooling, how is yours? :cool:
 
Big.Wayne has a skill of finding the nub of a problem that others have over looked.

Do as he suggests - it could resolve all your issues. However, from your description, sort your heatsink out as that is still an isolated problem all by itself.

Why do you turn your computer off? 72C is not dangerous. For example my q6600 runs 85C in prime95 with no problems.

I read in several forums that 72c is the max the q6600 should go before I should start worrying. So I did worry and turned it off lol.

I have some experience with the Vcore side of things, but not too much so I tend to just check other quotes and use them as a reference. In the Asus P5n-t bios I set the Vcore to 1.325, the fsb as 1333 x 9. But left all the other voltage settings as AUTO.. Then In windows Cpu-z reported the voltage as 1.2.. The Vid I think.

I'm using a coolermaster Cosmost 1000 case, with ample cooling. I say ample as it has two fans at the top sucking air out. One at the back of the chassic (next the the cpu) sucking air out. One at the bottom of the case, sucking air in. One underneath the harddrives sucking air in. And also one more attached to the hd enclosure facing towards the pci-e slots (pushing air towards them).. It feels cool inside. Coretemp reported the case temp as 32c.

I'm also having problems with my brand new Corsair 650w Tx psu, it's swining at me everytime I move the mouse around. This is just after I boot the machine, and the computer is Idle on the desktop (Cpu 0%).. I put my head next to the psu (death wish) and it was definately coming from there. My psu is reporting 11.77 on the 12v rail, which I don't understand.. The upgrade i made was to make sure I've more power running for the Q6600.. Yet my psu I used before this new one, a 600w, 18a x 4 12v, was showing 12.044 on the 12v rail.. So how can a new Corsair 650w tx show less on the 12v rail?? I don't understand it! Sorry to bring this into the post.

I had my previous setup running rosy until I decided to take out the e6400 and accidently snapped a few of the pins on the motherboard, leading me to upgrade to a new s775 mobo, the Asus P5n-t.. If it's running fine, don't mess with it.. I should have took that onboard.

One other thing.. I have not formatted the machine since I installed the new motherboard, which I wen't against my basic instincts there. Reason being my older mobo was a Nforce chipset, just like this new motherboard.. So I booted straight into Windows 7 as normal, with my new Psu, Board and q6600. Just in case it may be linked.

I appreciate any time you take in helping me solve this.

Quick post as i'm going out.

Your case cooling sounds fine and your lack of windows re-install shouldn't be causing your temps to shoot up - just look at the 'Resource monitor' if you want to confirm this.

I haven't checked your voltages but regardless you've really got to get your heatsink secure on top of that cpu - either via adapting your present one or buying another one.

The concern is that the heatsink shouldn't be that loose and therefore is the most likely candidate as the root of your problems (along with high voltages if you have set them on auto).

I would set your voltages manually as Big.Wayne advises and re-sit that heatsink securely - either: one or a combination of the two should see your temps drop.

EDIT: Your 12v rail is within tolerannce - it's fine.

I've just reseated the Asus Silent knight II hsf and put the clocks back down to default *(auto)..

Running Prime95 stress test (lots of cpu) for 30 mins produces 55c core1, core2, 3 and 4 = around 51c each. Is this normal for stock? My room temp is about 20c. Thanks.
 
Seems about right for stock settings, but a lot will depend on the ability of the hsf and case airflow, some coolers will obviously be better than others, as an example my arctic freezer gave load temps in the high 50's under load at stock, whereas my TRUE kept them in the mid 40's.
 
Just reseat or did you file any of it down? Loose heatsink is definitely not a good thing, but I'm glad your temperatures are better.

Id have thought that vcore was very high for 3ghz, its a much better idea to set it to the minimum required to be stable at stock and increase it only when you need to, and then only by one notch
 
Ok guys, running prime95, max cpu etc for a further 30 mins @ 3ghz has not put the cpu over 62c.. Is this a good thing?

Btw, I've somehow got the hsf to lock down so it doesnt sway.. So I think this may of helped a little.
 
Seems a bit on the high side at 62c, particularly for the clock speed, what speed does the fan on your cooler run at?
