Can't get my Q6600 temps down...

So right now I'm at 9x350 1.32v, 900mhz ram, I am getting 46C idle and it would probably go up to 72 or higher during p95 but I always stop before it hits 70. This is happening with a ~24C ambient temp!

I'm currently running with my HDT-S1283, a heatsink that is supposed to give the TRUE a run for its money. I have tried re-seating with more AND less AS5, using different application methods, etc, and nothing really makes a difference. I even tried switching the direction of the heatsink to no avail. I purchased a bolt-thru mod, didn't help AT ALL. I talked to a few people with similar heatsinks but much higher ambient temps and much higher vcores and clocks, and they have LOWER temps...

I am really at a loss of what to do about this. It seems as though I should have significantly lower temps. I have a few options that come to mind... That is assuming I just didn't get a totally crap chip. I just can't decide what is necessary/what to try first.

1) vdroop mod? could get me to a lower vcore requirement, but I don't think itll change temps much, its already low. Up side is its basically free and totally reversable should I accidentally break something.

2) lapping? I'm scared to lap the HDT base after hearing of nightmares involving very thin copper on the pipes. I did hold a razer up to my CPU and saw quite a bit of light in between, but it could have been an uneven blade too. I need to find one that I know hasn't ever been used and try again. My main worry is that I will turn out to be horrible at it and make it MORE uneven, or lopsided.

3) water cooling? I would like to go water, but I can't afford it and tbh I'm a bit scared of shorting out my system with a leak or having a pump die. My only water cooling option at the moment is this kit from swiftech. http://www.newegg.com/Product/Produc...82E16835108076

Anyone's constructive input is welcome! And sorry for the essay.

Air cooling is only good as ambiant temps inside. It does not matter how good a heat-sink/fan you have for your cpu. Just because other people have higher clocks at a peticular temp for their cpus does not mean that yours should be the same for several reasons.

Even if you had the exact same case, fans,and every component was the same you would still not have identical temps...no one cpu is the same...

What is your vid???

This for starters is a good place to begin your thermal/oc issues.

Also, that http://www.newegg.com/Product/Produc...82E16835108076 water cooling setup is based around a 220 radiator...which is very small, remember that you do have a quad. Stock they are hot...oc a quad pushes the temps in a loop up quite high...also you would have the same ambiant temp limitations.

I see no reason why you should not go with a 360 radiator...a fusion cpu block...and an economical pump and tubing from your local hardware store...for $2.00. Pump can cost $10-15.....

If you want to kit just for your cpu...then go ahead and get the one on newegg. But, I don't recommend that if you only want cpu then get a coolit : http://www.newegg.com/Product/Produc...82E16835227001.

The best thing you can do is to get components that you will be able to " GROW WITH ". This means that in time you will go from having your cpu in the loop to chipset, ram, gpus, hdd, etc.

Additionally don't throw money away...buy things that you will be able to resale...the coolit system you can resale...the other you'd be hard pressed getting anyone to buy that off you.

If you get a D-tek fusion cpu block you would be able to sell that very fast...same with any 360 radiator.

For starters, my VID is 1.225, which I thought was pretty decent.

The main reason I don't want the 360 radiator is because I have nowhere decent in my case to put it. The only place would be along 9 CD bays, which leaves me no room for my hard drive.

Hmm that's interesting...yes that's a nice vid...look I think custom would be best economically and performance wise...the time you spend on either an outright bought setup & a custom one is virtually identical anyways...just read and research as much as you can about everything...if you have any questions you can likely get them answered in here.

can I ask why you wish to have an internal radiator or reservior? While there are wc setups that are designed to fit into a case...and custom ones placed like wise, they do tend to increase the likely hood of splashing your expensive components this can short out things...

Then there's humidity...if for any reason you sprout a leak(no one plans on leaking)and they do happen...then for all intents and purposes your pretty much !@#$ed~!

I don't see anything wrong with having an external radiator regardless of what size you choose. Are you planning on carrying your pc on your next plane trip to Hawaii???

I am not planning on moving my PC too often, but I've modded it quite extensively and I would hate to have the nice look ruined by a bulky and ugly external radiator. Not to mention, I just don't have anywhere to put the external rad. My tower BARELY fits where I want it to as it is, and I am planning on building a new desk to better accomodate it. Water cooling in general is a risk of sprouting leaks, anywhere along the loop. Moving the rad outside is only removing one possible leaking point.

You could...
Mark the heat pipes with a black or blue magic marker...
Lap only until almost all but a hint of the marker in the groves is gone. That way you don't sand any deeper than the current finish but remove most of the offending material.

Are you saying he should sand the heatpipes??


Am I not getting something? That seems like a VERY bad idea!

Why would someone do this again? What exactly will it accomplish?

Odds are you have a very concave IHS on your CPU. You need to lap it. Don't look at this as a negative look at this as a positive when you lap. You are going to decrease your temperatures, and in your case probably very dramatically.

It is not hard to do it all, I have about 0 mechanical know-how, and sanding it sounds scary at first cause cpu's are expensive, but it's virtually impossible to sand it wrong, and if you take precaution to cover the contacts almost impossible to destroy your CPU. There are plenty of guides available, and I wouldnt use any water, sanding dry is perfectly fine and easy to execute on a s775 cpu because you dont have to worry about bending any pins on the processor like in the old days.

Not to get off topic but this: "Life is Learning, Learning is Sharing, Sharing is Life"
"Overclocking is like a drug addiction, the difference is we go broke improving our brain cells instead of destroying them!"

HAHAHA...that's soo funny and true too.

It is a G0 stepping. I am considering purchasing a lapping kit. I will try the CPU but I am not comfortable sanding down the heatpipes. If anything, I'd want to sand down the metal between the pipes to allow more pressure, but that kind of precision isnt easy, if even possible, when it comes to lapping. I just tried lowering the multi/raising fsb for the same clocks but couldnt get it stable on a lower multi. I'm starting to think i may have an unstable 780i as well. I also just did the vdroop mod, its allowing me to drop voltage a notch or two but NOTHING is helping my temps much.

EDIT: Just dropped it to stock speeds and vcore of 1.225 (the VID)
It's idling at 41C and loading at ~54C. Still WAY too high for this heatsink, that's what I would expect out of the stock heatsink.

My friend has OCZ VENDETTA 2 Heatsink overclocked his Q6600 AT 3.4 1.37V
IDLE AROUND 44,45,42,43 LOAD PRIME 95 - 66,66,59,59
HIS ROOM IS TEMP - 22C

I just told him to put his q66600 to default clock

2.4 CLOCK
IDLE AROUND AT 42.42.38.40 LOAD PRIME95 - 52.52.48.47
ROOM TEMP 22CC
He lapped his cpu and heatsink i think the temperature is normal for this type of heatsink.

hmm. Well I just changed my GTLVREF to +25 on each lane, and it allowed me to run the cpu at its VID at 3.0ghz stable, which is giving me an idle of 40 and load of 60. I am satisfied for now, but I will be lapping my CPU (and maybe the heatsink VERY SLIGHTLY) soon.

By the way, tell your friend to lower the voltage to default as well, otherwise the temperature won't change much.

Im in same boat as you i got a low vid q6600 and getting crap temps tho little better then you i reseated my tuniq tower about 20 times always getting same temps i thk its our chips just run hot.

Not to be off-topic, but where the heck do I get one of those!?! And what's the clock speed on that beast?
