De-lidded 3770k!!

Nailed it.

(re-post from reddit on removing IHS from a SB CPU, lol..)
 
Hello everyone,
it is my first post here and this thread is the reason I signed up on this great forum.
I bought an ivy I7 3770k in the summer and couple of weeks ago i decided to de-lid it as the temps were too high. I reckon I didn't spent too much time reading all threads available around about de-lidding, just watched 3 videos and i thought it will be a piece of cake.
I used a classic razor blade, that old fashioned type of, which is flexible. It proved to be difficult and in the end i managed to remove the ihs but I nicked in various places the cpu's pcb. Surprinsigly the cpu works, not fully but it works. The only problem I discovered so far is that channel A of the memory, the first 2 dimm's near de socket cannot be used. so i can't run in dual channel and i can't use the first two dimms at all, the motherboard always hangs with an error code displayed on the 2 digits display if I stick any memory module into those first 2 dimms. The 3-rd and the 40-th dimm's are ok. I haven't tried yet the integrated graphics, i have no clue if that particular area got damaged too or not, as i don;t have a hdmi cable nor a monitor with hdmi input. I'll buy an hdmi-dvi adapter and try the integrated graphics too in the next days.
If needed I can attach some pictures, I did my best to catch the nicks in detail but I think a far better macro objective was needed. I don't think it is any way to repair those traces, they're so thin, barely seen, maybe under some Leica microscope ( I worked with that in a cell phones plant). I was wondering about using some green pcb paint to cover the nicks/scratches then find some black rubberlike silicone sealant or epoxy and reseal the lid and finally send it back to RMA. Maybe those who'll open it later somewhere in some intel facility will understand that for a high end 3770k cpu we deserve some decent thermal paste or some indium soldering. After all the production costs for one 3770k are the same as for the cheapest Celeron they produce, what's the big difference for a drop of higher quality TIM? It's crap as I spent one month income for such a cpu and I know it was my mistake to try and open it but...I was not comfortable at all with temps around 70C all day long. Yes I was using the lousy cooler they provided along with the cpu in the box.
So where (in Europe) could I find some black sealant like Nickolp1974 linked here, apart from Amazon.
I'm from north western Romania.
cheers.

I think if you take a knife to your CPU and break it that's at your own risk.

50% agree with you :)

For the rest of the 50% i'd say that the reason why someone ends up walking risky paths is a consequence of a 50 cents Intel' save for each cpu. I call it money eagerness, while pricing ~400 euros for a cpu, at least they should have the decency of not putting in the same boat the premium products/customers with the entry level or mainstream ones. It is a matter of respect or common sense shown to a premium products customer in the end. Why should anyone buy a K product, why should you launch as a producer such a niche product? Of course for a certain niche of customers who might expect something else than 70C temps from that niche premium product priced premium.
If I buy a Mercedes or a Rolls I do not want to see issues common for Skoda or Dacia.
I'm sure that the production costs of any cpu aren't higher than 10$ the rest is probably invested back in research of a new technologies. 50cents additional cost per item spent for the let's say 5% whose the market niche taken by the premium K products might not be such a tragedy.
Anyway, everyone is free to choose whether to open it and use a better TIM or not.

@Winston: i think the idea with fishing line might be a good one as long as you could place the cpu into something that will allow you to rotate the entire assembly with decent speed while the cpu stands firm into that...something and the fishing line is used as a cutting line held in your hands and moved around the rotating assembly. Yet I believe the start should be done in one corner by some nonflexible razor blade.

Hi negura, you could try the auction site or maybe a autopart center could help
 
Hrm, i don't know i have some pipe freezing kits at work at its get pretty seriously cold but i don't think it would become brittle and twist off, even with ln2.

The best way really is a stanley, patience and small amount of luck.

I just let the clamps hold it in place but with liquid pro it does act as a glue somewhat and will hold it the securely enough whilst you transit it around the table to the case etc.

I've decided I'm going to do this, going to try fishing line I think

Did you rebond the IHS back to the CPU or just let the motherboard mount hold it in place?

Let us know how you get on, and if it does not work and you decide on a blade make sure its a new one, the sharper the better as it requires less force and lessons the risk of damage, good luck ;)
