hey guys,
i wanted to remove the IHS of my 6000+, but i didn't manage to do it. The silicon is cut, but the IHS wont get off ...

i found this picture. Did anyone of you have some experience removing IHS on windsor CPUs? dont want to damage my 6000+ ...
cheers
its soldered you, its not gonna come off without the core
of course it is possible to remove the ihs without ripping the core.
first you have to cut the silicone. then you must heat up the ihs (lighter, soldering iron) to melt the solder.
try to pull the ihs up... dont use force, it has to pop without much force!
Have a look at the tutorial for S775 CPUs. ;)
Umm, I wouold mention, if the core really is soldered, its going to be getting a REALLY good heat conduction contact with the IHS. Much better than with plain old goop under the hood. So it really woouldn't help much going neked vs staying covered.
I agree, I wouldn't go through all that trouble and possibly killing your cpu. Just lap it if you want better temps.Quote:

AFAIK, we never forced anyone to remove the IHS. It's completely up to you to decide whether it's worth it or not.
The question was: Is it possible and if yes, how. We told the threadstarter how and that he could benefit from better temps afterwards. There will never be a gurantee, though. And I think I don't need to mention that there will always be the risk of damaging your CPU or even your motherboard (indirectly).
BUT, where are we here? ;) Is this XS or am I missing something?
Brisbane 3600+'s aren't soldered, but windsors are.. odd.
That's the real question. Are the Windsor's soldered?
My chip is a real gem, I would love to go neked but not if it is soldered. Not worth the bother.
Even if you get the lid off, there is now solder on the core surface, you need to deal with "leveling" or removing it, and this isn't childs play.
As to the other points, sure.... hell even the core could itself be installed on the substrate crooked... and there isn't any way to fix that.
Best solution to crooked anything is alter your HSF mounting mechanism to handle any crookedness. Conform to the actual level of the IHS or core, not some "virtual" flat ideal chip. Spring loaded hold downs, etc do just that, take up the slack for any non-level manufacturing defect/tolerance on the chip itself.
Ill hold off even finding out until more people delve into Windsors and determine if they are soldered.
Best solution would be the Micro-torch from RadioShack, just heat the center of the IHS after cutting the silicon COMPLETELY for sure. The core/IHS should seperate with almost NO pressure once the solder melts.
Weird why AMD would bother, not like they have a rash of millions of IHS pullers out their. Sounds more likely they would do it to improve cooling.
I have that cpu, they claim if it says 2005 on it, its soldered.
I read the solder melts at around 100C which is nothing and it can be removed by your nail from core as its soft.
I am thinking put the sponge on pins that came with CPU to stop bent pins, get some kinda toolmakers clamp/vice, pop complete CPU in a Oven at around 50C for 10mins to get warm uniformly like running in a PC on load, then take out oven and heat with something like a shielded blowtorch or similar like paint remover gun again with heatshield as not too hot, and as the IHS gets hot and solder melts the weight of rest of CPU will let it fall onto worktop.
Obv cut your silicon 1st but I left that put as obv, test it with a thin piece of thread to make sure its got a gap all round and thread wont damage smd's.
Thats interesting since there are 939 opterons made recently and they aren't soldered (mines a 0704 and it only had grey goop, and i've seen much more recent ones with goop as well). . The yellow square on the bottom of the IHS in the OPs post suggests thermal epoxy rather then soldering to me :S
Does your IHS say 2001 or 2005 on it ?
I think I'll try it this was today:

True, but if the solder contact is good, then all you need to do is lap the ihs and you'll be good to go. It won't be the same as removing the ihs (as the heat builds up under the ihs and with it off the core gets a bit of airflow, which I find helps with the temps a tiny bit), but it'll still give you a nice temp drop, especially if you lap your ihs tooQuote:

Then it was either not hot enough (you know that for you, probably 60°C feel freakin' hot, while the solder will at least need ~85°C to melt) or the silicon wasn't fully cut through.
I agree with celemine, you didn't heat it up enough. What you should do is make a brace for the cpu, then just heat it quickly to 85-90c~ (if you do it slowly, there's the chance the solder that holds the core in will melt too) and let the ihs pop off. You should have to pry it off, that'll destroy the chip
