Lapped core 2 duo IHS pics

[cool_dude]

Real nice RockfordFosgate. What improvments have you seen in temps? What were you're temps before lapping and after (idle & load)?

[RockfordFosgate]

@cool_dude

Thanks.

Before:

Core1:45 Core2:48 @3.6 1.4v idle///Load: 50 53

After:

Core1:44 Core2:45 /// Load:48-48

[Leeghoofd]

Your cores idle at 3°C less then load ? mine bump up from 38° to 55°C under load...

well, unless you ambient temp is very low or you use very little vcore. otherwise i wouldnt believe you.

I decided to ditch aircooling and go straight for watercooling I've been looking for Swiftech H20-220-APEX-ULTRA+ kit for cpu/nb/gpu cooling.

Ahhh, watercooling. Overkill is never enough! But then, that's why we're all on this site! Glad you found something that works and makes you happy. I'll go that route one day...maybe later on this computer or on my next. Always bigger and better than the last!

These are some ridiculous pics guys.

Good job.

heres mine its not a dual core but its a conroe the L model to be exact, you guessed it right its a one of those new celerons that have a conroe based architecture

Great work, excelent finish. However, one question comes to my mind... The new Cellys can almost work without a heatsink (bear with me, please ), and can join the 100% OC club with the stock voltage (not bad) AND cooler (which is HALF of the E21xx coolers, without even a copper center). So, you lapped yours because...?



Kidding, of course. If you run it stock (cooler and speed), please undervolt it and tell us your temps. Since I'm getting something like 5ºC above room temperature at idle with my undervolted non-lapped E4300 (stock cooler), this HAS to be a sight... hehe

Cheers.

the reason i lapped the ihs was cos the contact was really bad ... and i don't undervolt anything ... ever.
i'm a overclocker and my main goal is ALWAYS the highest possible clock speed that i can achieve with my gear.
the word undervolting does not belong in my vocabulary. im all about speed.
the highest i have gotten that particular chip is 3.8ghz with 1.64v temps were at idle 40c and on 100% load somewere around 49-55c with water cooling.

check out my thread for other results: http://www.xtremesystems.org/forums/...d.php?t=149459

I figured the lapping was for OC purposes. I was just teasing

Still, even after lapping and with WC, those temps seem rather high... I saw your thread about that CPU, and it almost seems you got a bad one... The other Conroe-L thread on the forum doesn't even need overvolting to reach the 100% OC mark (and since it is (still) running with the stock cooler, temps should be below 65ºC). It also tops out right after that, but that's another story... lol

Anyway, great work. I'm not an OC'er (no time and no funds to replace something if I break it, though I do have an E6400 and a P5B Deluxe... hehe), so what you guys do is just awesome to me, and (almost) anything I say may not prove to be right or even meaningfull. But damn, those are some wicked results...

Cheers.

well actually i thing that core temp is not showing the right temps.. cos now that i think of it, the temperatures remained the same at 3ghz and 3.8ghz witch is basically impossible. since 3ghz was gained with stock voltage and the 3.8ghz with 1.64v.. so something is wrong there.

I'm going to lap my QX6700 soon. I may lap my FuZion as well...

argh are you serious... lapping your fuzion is a sacrilege, and besides the base of that particular block is really flat the begin with,
and i don't see any point in lapping it

Well, while I do agree those temps are a little strange, don't forget you have to factor in the adaptation period of the thermal paste/grease (which could account up to 5ºC), and the thermal conductivity of some materials. You might just have a block that isn't all that good transferring small amounts of heat, but that increases that capability with more heat applied to it.

I think I have seen this happen, at least with air tower heatpipe coolers (you can see that on the Anandtech cooler reviews), so I don't think I'm bending any law of physics just by telling this...

But if those temps are really off, the most recent ones seem to be more accurate (and more likely to appear).

Also, can Core Temp just be wrong when measuring temps from ConRoe-L chips? They are new parts, after all...

Cheers.

I did the lapping job on my E6600 L626A115, and the temp's decrease about 5c but still the temp's are way to high I don't understand it any more, since I have second E6600 new batch so it work's @1.46v and 3.550 stable, Idle temp's are 32c both core's, and the lapped one I have it on 3.6Ghz and 1.4v and the idle temp's are over 48c and it's really good lapping on it also on my Scythe Infinity, same cooler on both cores, the on with more voltage is much cooler then the other with less.
Anybody any IDEA what else I could do, since I know this cpu would OC very well but not with those high temp's.
Thanks

Having a weird one with my pc below.
CPU idles at about 38c on XP and on Vista 46c. Weird!.
Have ordered a lapping kit and going to do the Tuniq hs first and then maybe the cpu if I'm still not happy with the temps.
So my question is which will give me the better decrease? The CPU or HS?

[Leeghoofd]

My 632A is also 5-8°C on idle than my 477G, A's can run high speeds with less voltage though put out more heat than eg B versions... (if I'm not mistaken)

I need 1.42 real volts for 3.6GHz on the 632a...for 3.6Ghz on the 744G I need 1.51 volts though this one runs 10°C cooler under load...

[Dede99]

so the A's are just hotter then the B's look's like it, no matter about the voltage
Weired but truth
@ Airblazer, Vista just needs power permanently so thats why you have higher temp's on it, and about the lapping I would say no matter what you going to lap best would be both cooler and cpu, but you will get better temps no matter which one you lap it will make better contact to each other.
Good Luck.

[Airblazer™]

Cheers Dede for that...hopefully the kit arrives today and I can start tonight..first time lapper so hopefully I screw nothing up.
This was a great post on lapping

[Dede99]

It was my first time also on CPU lapping just get enough time and do it slowly and there want be any problem, secure the pin side good so the dust don't get to it and it stays clean.
Good Luck

I lapped my U120 Extreme over the weekend. I used knife oil to make it easier and not leave scratches. I used 220, 650, and 1500grit wet dry paper. But it is not a mirror like these. If I start to do it dry it leaves scratches. Do I need higher grit sandpaper or will it finish like a mirror if I just keep doing it? Will it even make a difference between a flat copper finish and a mirror copper finish?
