what delid method is best?

[ScribbleMike]

Alright I have concluded that my 4770k is one of the worst I could have, getting 90c easily during a 4.4Ghz OC at 100% and 100c at 4.6GHz max load, what's the best method I should use to seperate the heatsink and cpu? Vice and Hammer? Razor blade? Any other reliable method? Thanks in advance

At that overclock your should be liquid cooling

If your Using stock Cooling and overclocking your mad

One of the better air cooled is Hyper 212

should separate with a little twist

Sorry forgot to say I was using an h100i

I disagree. Many chips will handle 4.5GHz fine on air. Removing the heat spreader should only be attempted for people who know what they are doing. Both methods work but I personally used the razor method because i was too lazy to go and find a vice. Was easy enough, dont see why people getting scared at this instead of hitting a cpu with a hammer. Removing the heat spreader will void the warranty! If your chip can do 4.4, it ain't the worst. Many chips cant get past 4.3 @ 1.3 Vcore.

The h100i coolers are rated as one of the better coolers available

As for removal "airplanegeek" suggested the better removal method for you with this cooling system.
Perhaps he can also suggest an alternative cooling method to suit you overclocking needs, as the hyper 212 although a good air cooler is probably not enough for your needs.

Either my h100i is bad or I just lucked out in the silicon lottery... I think I'll delid and to the vice and hammer method. I do need tips on it though

 

[Markkk]

I have not personally had to remove a h100i
The Shock from a Hammer through a CPU doesn't sound like a ideal plan of removal 🙁

Did you Glue it together?
Thermal paste should separate with a twist on stubborn but using heavy duty hardware scares me

Mark. What we are talking about here is removing the heatspreader from the cpu die, not the entire cpu from the heatsink

airplanegeek - I must be confused.... do whatever you want hammer the thing... like i give a care it's not my CPU that you want to destroy.. Seems like i've stepped on your toes... SORRY

I read "what's the best method I should use to seperate the heatsink and cpu? Vice and Hammer? " I must have serious 1st language issues and not understand my native English... frankly do what you like.

Sorry ScribbleMike i have no idea what i'm talking about best of luck with your hammer.

Removing the heat spreader will void the warranty!

As long as there is no physical damage on the chip's die/PCB, Intel will replace a delidded unit if it dies. I replaced two 3570Ks after openly admitting to their customer service that I ripped off the IHS, guy told me delidding falls under warranty as long as the chip has no physical damage on the PCB/die and you didn't throw the IHS away after taking it off.

Store refuses to replace it though, I guess they don't want to risk it, but Intel will take the chip. Gotta say, nice move from Intel.

I read "what's the best method I should use to seperate the heatsink and cpu? Vice and Hammer? " I must have serious 1st language issues and not understand my native English... frankly do what you like.

CPU's IHS stands for "Integrated Heat Sink", it's a heatsink integrated onto the CPU PCB for transferring heat onto the external heatsink (aka, cooler). For those who don't know, CPU cooling on IB/Haswell works like this - die > TIM > IHS > TIM > EHS.

You don't have language issues, you have issues differentiating parts of the CPU and it's cooling. 😛

So should I try delidding if I can replace it? At 4.2Ghz with around 20% usage the temps get to a max of 50c which is unacceptable for me

You keep mentioning frequency but it matters little, what does matter is at what voltage? If the voltage is low and heat is high, it may need delidding. If the voltage is high, don't even bother since the overclocking headroom on higher voltage is minimal without going into the extreme range where you risk frying the CPU outright. Also, do note that delidding is risky, the very act of hitting the chip with a hammer using the hammer and vice method can crack the PCB or damage the die, and you can easily cut into the die (or the on-chip VRMs) if you don't have steady hands or if the blade "slips" using the razor method.

And before popping the IHS I'd first have a go at re-seating the cooler, often when people talk high temps it's the cooler mount making the temps high, not the TIM under the IHS. H100i is a decent cooler and unless you're pumping the CPU full of volts like 1.4V and above (any half-decent 4770K should reach 4.2 at under 1.3V), it should be able to handle the heat without a problem on most units. If re-seating doesn't help and you're 100% sure the cooler is working (aka, the pump and fans work) and your entire cooling system is fine, hammer away.

Mine got to 4.4 at around 1.27v

I've heard a lot of bad things about the vice method. Mostly that you have a higher risk of creating small cracks in the pcb and die. I use a razor blade and it's fairly easy and straight forward. If you want to speed it up you can actually push the blade in a little by hand and then use a small hammer to tap it through quicker. It's all risky though.

 

[airplanegeek]

I used the razor method too. Got my 4670k @ 4.7GHz. 1.3 Vcore 2.1 Vrin 1.28 Cache V

 

[ThePCEnthusiast]

The razor method seems to be the cheaper alternative, but there is a big possibility that you might damage the PCB.

@WerneHR Is that true for global warranty as well?

 

[Spectre694]

Here is another good reference I didn't see listed. It is what I used when I first tried to delid.

[rwpritchett]

I just performed two delids last night. My first time ever. I used the vise method and it went very smooth. No dents, no scratches, and temps for both CPUs dropped 15C on air.

The IHS popped off easily for both. One was a new CPU, the other in use about 3 months. I used electrical tape to protect the IHS from the vise as well as the pin-side of the processors.

 

[Davil]

I made a new video for how to delid a 4770k with a razor and it only took about 5 minutes and worked quite well with no scratches or scuffs on it.

Delid Video

I'm very weary of the long term effects that using a vice and hammer will have. Granted there might not be problems right away, but you're hitting a thin piece of fiber glass with a hammer. Even spreading out the blow from the hammer you still have the shock from the epoxy being ripped off the board. That probably creates some microscopic cracks that are only going to get worse over time especially with all the temperature changes it will experience.

 

[klepp0906]

Ugh this thread confirms what I already know. Tomshardware isn't the place to be if your an enthusiast and ignorance is bliss.

Anyhow; the hammer never worked for me. Either too much adhesive relative to how hard I felt comfy whaling on it or whatever but so long as your cautious regarding the location of the IVr caps and keep the blade oriented towards the IHS slightly you will be fine.

I've done 3 that way now. I've also seen people cut into the package and expose the copper/traces which is ultimately GG. So the thinner and sharper the blade the better.

Good luck!

I understand that overclocking high end chips causes overheating, but why does my Celeron G1820 Haswell chip get unstable at 60 degrees Celsius with default clock and voltage settings? Yes, with the Intel stock cooler at 2000RPM (this is the max fan speed) my 53Watt Celeron overheats like crazy. The best result I got was 40 degrees Celsius with a Cooler Master Hyper TX2 Heatpipe Cooler at 1800RPM (loud), 50 degrees at ~600RPM (silent).

Intel needs to fix this... or maybe they could return to selling bare chips too in "tray" packaging?
