Presscot users, DONT remove the heatspreader!

[@md0Cer]

Well, this could be known information already, but a search didnt turn up anything and I thought it wouldnt hurt to post this anyways.

Looks like it is attached or bonded to the core in some way that is much stronger than the northwood cores.

 

[Jimbob7]

Yeh, Presscots and any cpu's with 30 'caps' on the bottom seem to be soldered.

 

[Kuroimaho]

Or maybe it just melts the heatspreader

 

[@md0Cer]

Ah looks like you guys already know. Oh well, couldnt hurt to post it anyways.

That is actually quite smart of Intel to do:

1.)Shows people not to **** with their CPU's

2.)With the core soldered or bonded to the heatspreader it is able to transfer heat better. I am sure I would get better temps on my Athlon XP if my heatsink was an integral part of the core.

Speaking of it melting the heatspreader, my Athlon XP hit 100+C temps for a very short time once, it is okay, but the copper insert on my previousely lapped heatsink was kinda darkened. The TIM looked a little funny too, so I would not doubt it if extreme heat can mess with the properties of the metal or the TIM, but pretty unlikely. I think it just discolored it all.

As for presscott melting to the heatspreader, I know you are kidding, but hey that would be pretty hard. Unless of course it had to do with the TIM, but [BBE]Jimbob seems pretty sure it was soldered.

I had my XP running at 2500 with 1.9V last year for 9 mths non stop Seti, when it started to degrade and I removed the cooler it was darkened like yours even the letters were visible on the block.

 

[@md0Cer]

Yep. I have had my 2100 palomino imprint its letters into the heatsink. I dont think that one was more of a function of heat though, just the pressure and the paint wore off. Or just the little bump of the letters pressed their way in to the heatsink. Copper is relatively soft I beleive.

Actually, I don't think intel minds people taking off heatspreaders, because that instantly voids warranty and I don't think how you can put it back on without everybody knowing it. I heard a few people got better temps after they took off the heatspreaders on intel, so maybe their heatspreader is more for looking rather than the effect? (Just like the heatspreader on ram lol)

 

[stan03]

no the heatspreader is there to protect the die

 

[nikhsub1]

Exactly right, Intel 'calls' it a heatspreader but all it does is create more heat... you need to go though 2 TIM's and a think chunk of copper before cooling the actual die. It's real name should be "Idiot Handling Shield".

ok this is true, but i didn't want to be so harsh

Good Point. I take back my number one in that post. Although there could be another view on it, perhaps to avoid people who RMA stuff they break becuase im sure they have people messing something up by taking their spreaders off and RMA'ing it. At least now you cant take your spreader off and RMA it becuase it is pretty much clear you are the one who broke it. Just another view on why they MIGHT want to solder it...but this is most likely not one of their reasons.

You sirs are both correct, it is just one more obstacle for heat to conduct through to get to the heatsink.

Old(er) news. I got told to lose that link in my sig

Realistically, IHSen are here to stay no matter how much we jump up and down about it. It does cut down on core crushage *shrugs* but may also lead to other problems and can inhibit thermal transfer.

 

[hUMANbEATbOX]

my 2.4c wouldn't like having its IHS taken off either.

 

[FIZZ3]

The odd thing to me was that when people had removed the IHS on the older models on which this was still possible, they usually reported a solid drop in temperature (4c or even more)- yet hardly any increase in attained clock speed! Apparently then, the temperature isn't quite so important (at least in this range) as sometimes thought. Not a very hearthening thought for those addicted to getting the best HSF or watercooling gear. :S

Oh..sorry for posting old news...I dont usually keep up with this stuff, but I figured it could not hurt to post it anyway once I found out.

As for signatures, unfortunatly only Seniors can have links in their sigs

Why not? Are they bonded to the core in that model too?

The temperatures of my CPU have also not made that much of a difference in stability and getting me a higher overclock. The way I look at a temperature drop, is the oportunity to slow down your heatsink fan for less noise, or the ability to raise the Vcore higher to get a better overclock.

I did notice an increase in stability with lower temperatures though. I was able to run my 1700 at 2.35Ghz at 1.75Vcore at 80°C. Now that I added two fans to my heatsink I am able to run at 2.43 or something Ghz at 1.75Vcore at 65°C.

yep, i've got a SL6Z3, aka a m0 stepping 2.4c.

its basically a cut down EE, you can get xeons with the same m0 stepping.

there is also a SL6Z5, the 2.8c m0.

 

[saaya]

the people who removed the heatspreader got lower temps and higher ocs... at least the ones i heard from.
