Pentium 4c Heatspreader - removal and reattaching?

[Almighty1]

Greetings everyone:

Does anyone happen to know how to remove the Pentium 4c heatspreader and then reattaching it? When I had to clean the last Arctic Silver 3 application, I used alcohol, soap and water to try to clean the hole on the P4c-3.2Ghz heatspreader and then tried to flush the inside of the hole with water using a syringe that the water flowed out the bottom of the heatspreader. I wonder if this removed any of the thermal interface material between the top of the CPU core and the heatspreader.

It shouldn't hurt anything. As long as you let it dry thoroughly. I wouldn't remove the heat spreader. I would leave it alone. You would do more harm by trying to remove and re-atatch it.

Hmmm, I thought one can use this method without actually doing any harm in the removal. It's reattaching that I couldn't figure out.

I have removed a couple carefully using a razor blade. I attempted to put the IHS back on one of them with Arctic Silver epoxy, and it never was right again... :brokenheart: The temps were through the roof, and the poor P4 died when I tried to pull it back off.

EDIT: If I were you, I would not fool with it......

Read this and remember it well.....


This is one of those things you don't FVCK around with.

Wow, now that is scary.... I thought replacing the TIM with something better might help. But I guess the worst case is that I'll just have my inside contacts at Intel swap my CPU for another one. Are later steppings usually better?

check the o/c-er's database

go here

there's a link to a database with the dates and stuff of the processors and overclocks..

On previous p3/p4 ihs removals the best reduction in core temperature has been around 3 degrees iirc. Not really worth the risk imo.

 

[Amorphus]

oh come on, its the same risk as having a normal AMD. ^_^

Technonut, did you apply the epoxy to the core?

=O

 

[dbwillis]

I put one back on a while back...I put AS on the core and then used auto gasket permatex goop to hold it on...put a wee bit on the edge of the IHS and then put it in the socket with the heatsink clamped down for a day tillit dried...I did NOT power on until it was dried....temps werent out of the norms...

 

[Technonut]

Technonut, did you apply the epoxy to the core?

No... AS3 on the core, and AS thermal epoxy around the area where the original seal was...

I've already tried that. They don't have any P4c-3.2Ghz CPUs at all.

That's what I mean... I've only seen people post removing the IHS and then using some quality Thermal Grease between the core and the HSF. But the core temp will probably be lower too if someone replaced the Thermal Grease that was there with something better as it should be atleast 2c better and probably helps in the heat transfer to the IHS from the core. Because I can't think that it'll be that much different than people with the ECS K7S5A, K7S5A Pro motherboards that unless they did the chipset heatsink mod, the system won't be stable where the HS on the Northbridge on that one uses the pink thermal tape so one takes it off and then apply AS3 to like the entire surface of the chip then at two corners diagonal to each other, add a drop of SuperGlue. Until people did that, the heatsink never got warm at all. So I think the IHS is the same theory in a way except you have to probably apply the AS3 to the core and then the SuperGlue to the edge of the IHS just like the way it the chip was and then carefully hold it down with your hands and then use something heavy on top or something.

Hmm, were your temps actually better than before you replaced the thermal grease with AS or is it still the same exact temps? The heatsink may not actually push all the way down though but atleast in your case it does. Someone mentioned on asusboards.com's forums to use SuperGlue which might work providing one can get the IHS on tightly so that it dries without leaving a gap which is probably the issue with Technonut since Thermal Epoxy takes time to bond so you need something to make sure the IHS is pressed tightly on the board.

The stock Intel heatsink puts alot of pressure on the chip/IHS...at least on my Asus board it did.
the temps went back to what they were with the IHS originally on...removing it did lower it maybe 1-2'c...but the ramp up and down was faster....

I don't have the stock Intel heatsink though even though I have a retail version of the Intel CPU. I heard from someone Intel used Shin Etsu G751 underneath the IHS so maybe that's why the AS3 didn't really helped as the Shin Etsu and PCM+ are supposedly the best out there right now.
