A further unsuccessful attempt to deledge an i5 4670k
A further unsuccessful attempt to deledge an i5 4670k
In short, I felt lucky and decided to try removing my cherished 4670k, which I've had for over three years—actually closer to four. The main tool I was using was too thick, making progress difficult. Also, the space between the PCB and IHS is quite narrow, which is actually beneficial as it ensures better contact between the die and IHS. Nevertheless, I thoroughly worked from every direction and stayed very careful throughout. Still, I managed to scratch a few sides trying to reach the IHS adhesive, and possibly the PCB on those edges as well. The small nick visible in the bottom-left of the CPU is notable—it seems to be the source of the problem, as it exposes a wire, which could explain the failure.
Looking at other failed attempts, similar scratches on the PCB can seriously damage a CPU, which is likely what happened here. After trying various approaches, I stopped when I realized I wasn’t making progress. Once reassembled, the computer wouldn’t boot, not even into BIOS. Even after several CPU reinstalls, the issue persisted.
I’m convinced that lightly scratching the PCB made it unusable. For others considering a delidding attempt, I won’t recommend it unless they use a reliable method. I suggest using a proven solution like the Rockit 88 Delidding Tool (http://rockitcool.myshopify.com/) or similar products. The BreakFree tool (https://www.entersetup.com/) looks promising but hasn’t been available since last summer, so its status is uncertain. There are also several 3D-printed delidding tools you can make at home for free, though I haven’t tested them. I’ll be using the Rockit 88 with my replacement CPU, so I hope to share my experience.
So, all I have left is to accept my loss and buy a new CPU. Unfortunately, I’m not financially prepared for that yet. But perhaps I can borrow some money from my college funds and use my GPU budget on the Rockit 88 tool, some thermal paste, and a Silverstone PWM fan hub for my ASRock Z97E-ITX/AC. This would let me run more than two fans and possibly overclock my original CPU.
Yes, I never overclocked my original 4670k for the past three and a half years. That’s why I’m doing it with my replacement, and I’ll push hard!
In memory of my dear friend... I need a reason to do this, don’t I? Maybe now is a good time to think about it. Any advice would be appreciated!

Can you lend me a Haswell CPU to try out the rest of your rig? I’d begin there if it’s feasible. I have a friend with a 4590, but that would be too much effort. It seems like my CPU is definitely gone—everything else has been replaced. So I’m stuck and have no choice but to spend money on another one... That’s the situation now.
I would consider trying another CPU first to check if the issues persist. In the future, I’d advise against delidding since you only gain a few degrees of cooling improvement. It’s not worth risking your CPU. I don’t have access to another compatible CPU, so that’s not an option. I’m sure it’s the CPU that’s causing the problem. With the new CPU, I’ll use a Rockit 88 delidding tool that’s reliable. After this attempt, I hope I can save $30 by using a razor instead of making the same mistake... My cherished CPU won’t be in vain!

I don’t have access to another compatible CPU, so that’s out. Still, I’m sure it’s the CPU issue.
With the new CPU, I plan to use a Rockit 88 delidding tool that should work safely. After this trial, I hope I can save around $30 by using a razor instead of making the same mistake... My precious CPU won’t be in vain!
You haven’t even tried opening it up, right? Don’t assume your case fans are sufficient, ignore any temperature concerns—just focus on trying to remove the CPU.
Keep in mind, this looks like a weak marketing move and seems like a poor attempt at selling something.
I would consider trying a different CPU on your machine first to check if the same problems persist. Going forward, I’d advise against delidding unless you’re willing to accept only minor temperature improvements. Not worth risking your processor’s health.
I don’t have access to another compatible CPU, so that’s not an option. Still, I’m convinced the issue lies with the CPU itself.

So far, you haven’t even tried any overclocking attempts, right? Don’t assume your case fans are sufficient—don’t bring up temperature concerns. Just because you’re thinking about pulling the CPU apart, keep in mind I specifically mentioned a particular tool for this purpose. Your effort failed if you hadn’t purchased it! Sorry to sound skeptical, but this seems like a weak marketing move and looks like a poor attempt at promotion.
Let me be clear. I’ve overclocked my graphics card before and done thorough research on the process for both CPUs and GPUs. It wouldn’t be difficult. Although I don’t have enough case fans for safe overclocking, I’m getting ready by trying to lower temperatures with a delid and adding more fans soon. Delidding wasn’t my initial idea for this approach. That would have been reckless. I’ve owned the CPU for nearly four years, so it’s not the first thing that came to mind.
I mentioned the tool not for promotion, but because I genuinely want to offer advice to others who might try delidding their CPUs and avoid making major errors like this. In short, I just want a safer and more effective way to remove CPUs so people don’t repeat my mistakes.
Fair enough, it really seemed odd that someone would take such an extreme step unless they were sure they hit a ceiling with regular methods... In my view, it's a "final frontier" treatment—high risk but almost no real benefit. I'm just someone who destroyed their Radeon 9800 Pro years ago by soldering a variable resistor to adjust the vCore, and then pushed it a bit too much, so I definitely don’t see myself as someone who sticks to the original specs.

Silicon Lottery will perform the delidding, apply Coollaboratory Liquid Ultra, and reseal the IHS for just a bit more than the tool itself.
Support the above commenter to have a professional handle it if necessary, though it's intriguing you'd proceed without other cooling steps first. What's your current OC level? Just note that once you delid, the CPU corners are very vulnerable to damage from even minor pressure imbalances, which could cause permanent harm as the IHS is mainly protective. It's best to replace the IHS promptly after installing a new chip. Recent delid tests on Kaby Lake showed a decent temperature drop but no improvement in overclock performance. Overall, the result suggests a much more fragile CPU or possible damage until the IHS is re-applied.
