FX 8350 IHS removed accidentally, HELP!

Hi, i accidentally removed the IHS from my AMD FX 8350 CPU when trying to remove it from heatsink. (I was trying everything it was brutally fused to heatsink).

some pics ->

Can i simply place the IHS back on? Or will it no longer transfer the heat properly? Do I need special equipment / solder to re-attach it? Can i just use some glue on the edges where it is black?

Aparently it is soldered, whatever that mean (http://www.overclock.net/t/1318995/official-fx-8320-fx-8350-vishera-owners-club/10600)

Thanks for your help guys. I didn't even know what an IHS was before doing some research, I thought i had broken the CPU haha

Sorry, mate. You've ripped the die right out. That CPU will never work again.

And does it have to line up too precisely in the socket that it would be impossible for the contact to be good if i just placed it back on?

Thanks
Yes you are seeing 2 halves of the die. It is 100% impossible to make this chip ever work again.

well. that is entirely depressing.
I had wanted to put it into another working motherboard and run stress test to try to melt the heat paste, but I could not put it in due to the metal lever that locks it into the socket blocking the heatsink.
Also tried running a hairdryer on it to no avail.

What i missed seeing which i read earlier was to put in in a oven pre-heated to 200c and then switched off and leave it in the cooling oven for about 30 mins. That might have worked to loosten up the heat paste but read that too late :***(

Holy Moses, this split is..... horrible and amazing at the same time. What did you used for thermal solution? Concrete? We had some really bad stucked ones, after years of not changing the paste, running for 10 years almost 24/7 with high temperatures, even then we still did not destroyed a CPU like that....

yeah like others have said you ripped the die right out of the PCB, AMD solders the die to the IHS next time you get the CPU stuck run prime95 for a few minutes before removing the heatsink it will loosen up the thermal paste.

I believe it was the stock thermal grease that came with the CPU / Cooler bundle from AMD. It was a gray color.
I have been using it in a computation cluster so It's had all 8 cores running pretty heavy. Not all the time but whenever i've been using it.

yeah i read about that unfortunately i could not do it as the motherboard was dead, and i could not place it in another board as the heatsink gets in the way of the metal lever that locks the cpu in place on the motherboard

I would Twit this to AMD or email them. It wasn't your fault that cement TIM they put on their cooler bonded with it.

I've had this happen to me in the past (both Intel and AMD). Wipe that crap off that comes with stock coolers and put some aftermarket thermal paste on heatsinks.

RIP FX8350, sorry Russian hammer method was not a good idea in this case.

Next time don't use thermal adhesive as TIM but a thermal paste and try removing the heatsink after it's been heated up a little.
If you've used the stock heatsink with stock TIM, bad luck, again needed heat prior to removing.

Such a dreadful sight! I can feel the pain...

Wow! The die is ripped away from the substrate. As others have said, it'll never work again. I'm sorry for your loss. The only gain here is the kudos for letting us all see the 8350 die, and as a cautionary tale to others to be careful removing the CPU if it's stuck to the heatsink. Maybe you could seal the die with clear nail polish, and make a keyring of it?

Well.......................You dont see that every day!

On the bright side, at least it wasnt a $1500 CPU, a direct replacement with a nice clean shiny IHS can be bought for under $150. This time I would not use the crap they send with them for TIM or one of the stock heat sinks. Get the CPU only and use the money you save towards an aftermarket heat sink, not like there isn't a million to choose from.

Ouch!

What a coincidence! I just killed an FX-8350 a couple days ago. The case was really cramped, and I removed the heatsink to clean the dust bunnies out of it. However the CPU was fused to the heatsink just like yours, and ripped right out of the socket, leaving some of its pins behind!

Fortunately it was a system I was in the process of decommissioning, but I had hoped to use it for something else. Not anymore.

Sorry for your loss. Just learn from it, and keep going.

RIP. This is the most catastrophic attempt to separate the cooler from the CPU i 've ever read. If you had asked help BEFORE attempting the "brute force" method, this wouldn't have happened.

I don't know if this is a stock AMD thermal paste or if it's 3rd party applied at a later stage, but this is also a good reason to find a paste you like and stick with it. Personally, since i am not going for extreme clocks, i 've always gone back to Ceramique II. Not only is it dirt cheap ( i recently bought the 25g syringe from Amazon offer at 7,40 EUR), but it's also on par with MX-2 (at least for my TDP usage they have 0 difference) and it has never stuck on me. I usually even forget to run 10 mins of Prime prior to removing the heatsink, yet it has never stuck. Another good practice is to never pull the heatsink up. Always try to twist it left and right gently, to start breaking the paste bonds and when you feel it has loosened, then pull. This way you avoid the probability of ripping the CPU out of the socket.

If this is AMD stock thermal paste, AMD should consider a new formulation.
