Missing IHS

Hello

I obtained a defective QX9650, with missing IHS.
My question is quite simple: how can I replace it ?

Buy a new at Intel (I doubt they sell IHS without CPU) ?
Buy another type of IHS (can it be found in OC specialised shops ?) ?
Adapt the heatsink directly on the die (using a lot of thermal paste) ?
Build my own IHS (which metal and thcikness ?) ?


All advices are welcome...
 
Was it really defective? Or did the previous owner remove it intentionally to do the third option you listed, in order to get a small improvement in cooling?
 
Wow aren't the recent Intel IHS's soldered....I've seen some horror stories of people losing their chip after trying to prise it off with use of a heat gun. TBH I would mount the heatsink directly onto the die for some sweet temps- I assume you bought it second hand off someone who has probably tried fiddling with it, and thats probably what they were trying to do if the IHS is missing.

And why did the previous owner, having removed the IHS, decide it was time to sell the chip?

Given how many disasterous articles have made their way onto the internet regarding the outcome of removing soldered IHS's from the underlying chip...I'd say the first order of business ought to be verifying that the chip even works correctly and wasn't just "elmer's glue" glued back onto the PCB after the prior owner ripped it off when attempting to removed the IHS.
 
Even if by some miracle it still works, I imagine there's a good chance that chip has seen quite a bit of abuse from the previous owner beating every last drop of OC out of it. IIRC, aigormorla's E8400 didn't last long under such conditions.
 
I will test and see soon... :/
I will try to adapt directly the IFX-14 on the die.

Do you think I should use thermal paste or thermal scotch for the contact ?
 
use a good amount of Arctic Silver Ceramique.

be careful with the IFX-14, its a heavy sink and you can easily crush the dice.

From what I've read of others who removed the IHS on the cheaper Conroes where the IHS isn't soldered to the CPU is that you have to remove the metal clamp on the mobo that holds the CPU in the socket as the heatsink will actually sit on that clamp and have a gap to the CPU once the IHS is gone.

I don't know if it is true...but you should seat the CPU and lock it in and then confirm by eye that the CPU still extends beyond the level of the cpu clamp.

Thermal paste will work fine provided you can make contact.
 
you dont need to replace the IHS....as long as the aftermarket HS/Cooler you will use actually touches the core.


Also...from your statements "using a lot of thermalpaste..." etc it sounds like you are pretty new to this. So i strongly advice to read up HOW to apply TP. In case of a single core without the IHS you spread a VERY thin layer across the core, using a credit card or similar. Then seat the 3rd party cooler on it. VERY CAREFUL since the chance is without the IHS the core might break!


edit: and no, no scotch. AS5, thin layer evenly spread over core.

Edit: Apologize..you probably meant scotch/lot of paste to fill a possible gap? 🙂
 
*sigh*

removing the ihs off a quad is one of the last things you want to do.

Now on a Quad you really need that IHS. For Protection.

My recomendation, ANY sink you get is a manditory lap required / brace if its a heavy sink. You need that sink dead flat, where it will pass ANY GRID test 100%. The slightest offness will drastically impact your performance.

Also i think you might even have to remove your retention system. your dies might not sit out flat once your retention system is in place. Your going to have to rely on your heat sink mounting system to hold that cpu in place.

This is also why people only hack ihs's off on either phased or watersetups. For air, and a heavy sink you risk cracking your die.

Lastly, you can not get an ihs and place it on top. The top is soldered on so you get the best possible contact internally. Without that solder, your going to see a big variance on core load temps.


Also I just picked up a QX9650 so looks like well both be having fun with a mean chip.
But the MAX and i say this MAX voltage you should apply on a long term load test is around 1.43Vcore from what im hearing.

And yes its a very pretty chip: <heres my stepping and bin info>

I have another question about this CPU.

There is something looking like tin on the die. Is it thermal paste, or really tin ?
Do I need to remove it before trying to adapt the CPU to the heatsink (with thermal paste) ?
If yes, what can I use to remove it ? Aceton ?
 
That is likely remnants of the indium-based solder that was used to fuse the chip to the underside of the IHS.

The only effective way to remove it would be to heat the solder above its melting point (estimated at 70-75C) and try to remove it as a liquid...but be careful not to overheat the CPU itself and desolder the IC side of the chip's bumps to the packaging itself.

Alternatives might include trying to sand off the indium solder (good luck).
