Don't have one around :)
I will see how it turns out when i mount. I never mount without checking the contact anyway..

Can you honestly say a half a milimeter concave or convex on the IHS is going to make your CPU run noticeably hotter? Like +5 degrees celcius or more is noticeable.
And if it's +5 Degrees hotter, wouldn't that amount to about jack all for the average human being? Not to mention Ambient temperatures would have a greater affect on an air cooled system than slight depressions in your IHS?
.5mm?!?!? Heck yeah! That's a HUGE gap! Ya better lap that shyzz son!Quote:

to the 2nd part. for the most part it would amount to about jack for the average human being. luckily the bulk of people who come to post/read here arent average computer users. hence the xtremesystems name instead of mundanenormaleverydaycomputers.org
Mine's fairly flat....slightly raised outside corners...just slightly.
Half millimeter? Doesn't sound like much, 500 microns sounds better and its a gaping chasm for thermal conduction.Quote:

A change in ambient of 5C can easily cause a stable overclock to fail. It all adds up, the idea is to remove as many obstacles as possible, heat is first and foremost.
Reference
cpu dT = (cpu load T) - (room ambient T)
Thermal Resistance = (cpu dT) / (cpu watts)
just received e6600 retail - pack date 8/07 - with sharp edges. Maybe all the newest builts have the "new" IHS. Surface is really good on this one - very flat!
im gonna have to pull my e6700 out and take a look now... it did have sharp edges... i do remember that.
and to the previous post about intel not making their own IHS.... why wouldnt they? have you ever stopped to take a look at all their manufacturing facilities... i live near one, and its the size of a small town. Pretty sure they make their own IHS.... quality control issues would be a huge concern if they didnt.
I got both a 6600 and 6300 this week(week 26 CPUs), and have had a 6600 ES step 4.Quote:

Waiting to pickup processor.. I'll let you know which IHS it has.
Wickedld9, nice meeting you at lacledes, my jaw still isnt recovered from those 7950GX2 stock 3dmark's. ;)
Mine looks alright (paste spread out by Intel HS\Fan):

Retail E6400, L624A848. Pack date: 7\24\06
That looks nice, im gonna check mine as my temps arent great it must be the ihs or the temp sensor
Hey if you don't want it, I'll sure take it off your hands and make the cooling work.
Interesting find though, that's like something I'd come across and just think I'm being retarded when I thought there was a difference. Good call though, I do in fact wonder what is up with that.
i pulled off my cooling tower (aerocool gt1000... yea i know its a POS). the thermal paste had spread out, but left spots where there wasnt any... not smooth like aggybong's... i cleaned the bottom of the cooler, and it was gold plated and looked like a 4y.o. blind retarded kid lapped it. So, i busted a move on that thing and lapped the hell out of it... two blistered fingers later, and it looks like a copper mirror... even polished it.
i just dont have the ballz to lap my CPU yet... maybe ill lap the 6700 when my 6800 shows up, and ill post the results.
i did take pics of the lap job, but my digital camera's flash is too damn bright, and when i take the flash off, it looks blurry... stupid nikon.
theres something i wonder if we have covered yet...
have we considered that maybe the stock intel heatsinks are CONVEX on the bottom?
i mean just an idea, but you have to look at it from intel's perspective, and think that maybe they dont plan for the 1% of conroe owners using waterblocks...

I wish they would just do away with all spreaders. They protect the core but add to the heat or as Cathar put it, they "dull the process of heat transfer".
IMO, all processors should come with a (detachable) shim the exact same height as the core. This way it would still be impossible to crush the core with anything less than a sledgehammer, but it wouldn't inhibit the heat-transfer either.
Too bad that 99,99999% of everyone who buys processors or computers in general don't even know that an IHS is, much less care about how it is implemented =/
-Stigma
I have a retail E6600 L625A481, it has the rounded edges, decided to lap the damn thing, and this is the result, nice temp drop for me. Quite happy with the result, I know my warranty is shot.
