S939 A64 IHS Removal

[Clairvoyant]

What is the difference in hieght on the core with the IHS removed.

All I would need to do to get the same pressure is to add the difference in packing out the springs that are screwed to the HS.

That should be the easiest way to do it. Should be better than filing anything down.

Has any one else done this with the following.

Asus A8N SLi Delux & Opty 170 and a Thermalright SL-120.

Would like to know if I need to file any thing away to get the HS to fit if I take the IHS off.

Thanx in advance.

Wouldnt recomend it with that cooler as i think its same as xp120 and they use clips. I tried it with xp120 and didnt fit. Have seen a guide on xs though with a xp120 and he used washers to keep the pressure. Best off with a cooler such as Big typhoon that screws down

About 1mm but just measure ihs when it comes off if you want it exact

Tempted to do this to a 165 when it arrives. I've seen a fairly small difference in temps give a fair increase in clocks on dual core optys. Anyway, noticed a stanley knife used in one guide. Anybody got experience with a stanley? That would be prefered over bare razor blades.

Depends on the blade. Most stanley knives are too thick. I just put a few strips of duck tape over one edge of a razor and then used that.

Right my lurvely 165 CCBBE 0615EPMW has arrived. Just getting the confidence up to put a blade to her

 

[joeyjojo]

Phew, all done. Core seems very low, almost flush with the little chips around the edges. Hopefully the waterblock won't crush anything

is this safe to do with an AM2 5200+ X2?

 

[joeyjojo]

I'm finding it really hard to get a good mount with my storm. It's trial and error really. Have to boot up and load orthos up to see if either of the cores have bad contact. If the temp rockets I tighten one and loosen the other. If it's the wrong side I swap and tighten the other one. After a bit of fiddling the temps remain low and fairly similar. Don't overtighten though, makes the pc shut down

No, it is soldered.


Joeyjojo: I haven't had any problems with my storm. Just tighten half a round on each screw and move on to quarter rounds after it's starting to tighten. I have tightened my up fairly hard, and my computer don't shut down! But when you're saying it, one core is slightly warmer than the other, I might take a look at it later.

thanks for the info, are all AM2 IHS's soldered as i can clearly see the black adehsive all the was round the IHS, i was just concerned about the position of the L2 cache chips round the outside

As far as I know, yes. Your observation is correct though, it should be black "silicone" substance in the edges. I just found a picture of a guy who tried to remove the IHS from his x2 5200+ AM2:

I came in and told the guy a few hours after he was done with the job

 

[Happy|Harry]

you mean to say the ihs is soldered to the core itself?

if so i take it that the black parts i see in the picture on the ihs beside the thermal paste are parts of his core

Yup, soldered to the core. The core was ripped right off... Needless to say it didn't work afterwards

Now, if you're still eager to do it, it is still possible. The difference is that you have to heat up the IHS to about 80c to melt the soldering. Ohh, btw, that is fairly risky

Well I have removed my IHS from my opty 170, fitted my 3rd hand Thermaltake Big Typhoon (needed relapping).

Now my idle temps are now down mid 20`s with 3 c between them.

Load up to the mid to high 40`s on both cores 1 c between them.

But It will not clock any higher.

 

[Jokester]

Even with more voltage?

[Clairvoyant]

I have put it up to 1.5.

But lets see now I have tightened up the screws.

 

[Hesky82]

my 170 was exactly the same, air cooling just couldn’t get the temps down quite enough. adding more voltage would just make matter worse, even if the temps were not going over 45c. at that time i was going to rip the ihs off but decided 1st check some better cooling out, ie water. the temps dropped dramatically to 37-38 on load and i found the cpu could clock much easier and would actually respond to voltage increases, which it didn’t before.
I never got round to removing the ihs in the end.

Just Removed the IHS to my 185 CCBBE 0613RPMW.
dropped my load temps by 10c.

Very brave on a chip as good as that one, lets see how far you can push it now

Yeah but i have the right blades for the job The ones which are doublesided razorblades but have one side covered with a metal strip to protect your hands.

First chip took me 45 mins
Second chip 20 mins
This chip 4 mins
My technique has improved with practice but looks like its a dyeing art with IHS becoming soldered on
