advice required delidding 4770k

Jamin280672 · 6 Mar 2014 at 14:38

So this weekend I plan to delid my 4770k, I've got everything now required to do it, but here's the thing, I've been using the cpu for a month or so now and I've heard that with use, the black glue that Intel use to stick the lid on with gets tougher, is this true ?

With this thought in mind it left me thinking, should I use the knife way or hammer and vice way, so I brought both, I figured I would gently cut the corners and just slightly into the 4 sides of the cpu to loosen the glue then move it to a vice and finish it off with the wood and hammer, does this sound ok ?

And for my last question, I'll be using coollabs liquid ultra on the die, very very conductive, so what do I protect the VRMs to the left of the die with ?

Thanks

I used a knife. It's not easy and you have to be very very patient. Be careful when going around because those VRMs are also easy to nick when you're running out of patience.

I used CLP instead of CLU and if you've applied it properly then you shouldn't have bits of it flying off the die towards the VRMs, but if you are a bit worried, then I would have thought a coating of nail varnish would suffice.

Thanks, looks like I'll be raiding the Mrs makeup box this weekend too, I've watched loads of YouTube videos regarding delidding and seen how close the VRMs are to the black glue which is why I was going to use half knife and half vice way, no chance of cutting into anything then, this will be my first delid ever, I am a little nervous, but more interested in sorting my rubbish temps out, there's 15oC difference between core 1 and core 4 and it's not the waterblock mount, I've remounted that a million times and used 4 different TIMs.

I used a hairdryer to heat the glue which made it much easier to slide a blade underneath.

Vice method is safest. Believe it or not

Before you do any method you must think "Can I afford to buy a new CPU".

Jamin280672 · 6 Mar 2014 at 18:20

I know accidents happen, but I don't intend on killing it, if I ha e to take 20 breaks inbetween each cut then so be it

I would have used the vice way only if it had of been a new cpu but as it's used now, I've read the black glue stuff they use hardens after use, I'm worried it will take too many hits to get that sucker off, which is why I thought about loosening it up a bit first with some small cuts.

I've only seen 2 guys use the hairdryer way and one of them heated it too much and cooked the cpu, might be worth a quick go to help soften the glue though

Hi,i attempted a delid on my 3570k,i followed all the guides using the knife method,and i took loads of care and time,i managed to put an increadibly small nick in the pcb that i could only see properly with a magnifying glass,the cpu never worked again !!!
I would recomend warming the glue and then use the vice method
PS i would never bother ever again.

i used vice method on 4770k took less time and was much easier then using Stanley blade on my 3770k. if you use vice method dont be afraid to give it a good whack you might be surprised how much force it takes to get the ihs off

two big blocks of wood laying on a worktop

put cpu in the middle of the the wood blocks and place one end touching the cpu cap,the other end touching the cpu pcb and whack it

no vice needed

don't worry about the glue n how old it is,the cap will soon come off

Someone should ask intel not to glue down the IHS on future K cpus.

Now thus is one I've not seen before, but can see how it would work, might have to give this a try

Jamin280672 · 6 Mar 2014 at 20:39

I hope this next question makes sense, but whether I use the 2 blocks of wood or vice way, do I put the cpu in the clamp what I would class as sideways so that it's basically being hit at the sides, or the otherway around so it's being hit at the top and bottom ?

wazza300 · 6 Mar 2014 at 20:47

If a vice you clamp the metal cap that sticks out both sides and tap the PCB with a block of wood

If no vice use two wooden blocks above with one on the cap that sticks out and other on the PCB (the flat edges) and hit till it comes free,you only need it to move slightly

Thanks for your help guys, I'll let you know how it goes

I think after the complaints with Ivy and Haswell, they wont be using TIM again, they will probably go back to soldering the IHS on.

Would you be willing to bet on it?

Lol, no not a chance, completely unpredictable, by the time I upgrade my system next, which won't be for a few years now, hopefully Intel would have sorted themselves out.

I want to change my current Gigabyte Sniper Z87 to the Sniper 5 when the price comes down a little and also want a new PSU, those will be done over the next year or so.

Thanks for the help guys, I went with the Craft Knife way in the end, I was surprised how easy it was to do, once I squeezed the knife into one corner it went through like butter, the hardest part was just getting into the first corner, I marked my blade with an ink pen and decided I wasn't going to go any further under the IHS than that mark to save damaging anything, when I got to the point where I could slightly wiggle the IHS, I gave the CPU to my partner who has very long nails and asked her to get her nails under the IHS and prize it off.

I will post some pictures later, I did scratch the PCB slightly, but its not effected the CPU, all is working fine, I used some window silicone sealant which is good upto 160oC and one of the brushes I got with my CLU to apply it to the VRM's, its water proof and non conductive, I then applied CLU to the die and put the CPU back in.

Temps are way way down, im very surprised, didn't expect this much, I am defo gonna try and push this cpu further, now hitting a max of 62oC on each core evenly in IBT, before delidding, core 1 was hitting 90oC core 4 was hitting 75oC and the other 2 were somewhere inbetween, they are all around about the same now.

Thats quite an impressive drop. Saw a vid once on yt were a bloke delidded his by using a hairdryer to heat the chip up, softening the adhesive whereupon the lid simply pulled off with a fingernail slid under it.
