After delidding my 3770 K I can honestly say it was well worth the effort. I also lapped the IHS only I left my H-100 alone. Used some LMP via die/ihs for the outside IHS/PK-1 the results are amazing almost 30 celsius across the board.
In my observation prior to appliying LMP I can honestly say that if you are gonna delidd use liquid metal otherwise results are gonna be mixed. The gap created by the glue prior to delidding does cause some heat but the main culprid is the lack of soldering. LMP has that effect on this process. I started with Artic Silver 5 and was not impressed . do not get me wrong artic is awesome but is not soldering. Even with the temperatures under control Ivy gets very VOlt hungry when you get past 4.95 GHZ at least my chip. I tried 5.0 I could not get it stable.
I will keep the chip running when I use Fsx at 4.8 I do not think the 200 mghz are gonna buy me that many FPS. My CPU is happy at that speed now a days thaks to delidding and the LMP.
I have read in many forums people are very scared of LMP but I found it to be easy to deal with except when you apply IHS/FSH You must likely have to lapp if you are the type to take system apart all the time besides interestingly enough PK-1 Performs better under those circumstances go figure.
In conclusion I m impressed with the results and I would do it again if I had to it's worth the risk besides Ivy is a very resilient chip. YOu probably would have to apply direct electric shock to kill it. Intel created a great product but forgot to glue it back together.

Any estimates on what types of clocks and temps you can get on a stock cooled + delidded i5-3570k?

So what is holding the IHS to the PCB? I have been contemplating doing mine, but I want my IHS to stick to the PCB not just relying on the socket retention bracket. I would like to be able to resell it one day.

So you gained 200mhz from the experience?

- I understand its all about the experience, but still, worth it to some, not to others :)

Well the bracket holds it pretty steady. I would not put any type of adhesive as it would certainly cause uneven temperatures. Do remember as you see on my Pre delidded cores there differences as far as 10 celsius, although IDONCARE explained with a chart why some cores run hotter than others but once you delidd it brings them within 4 to 5 celsius not 10 or some cases Ive seen up to 15 celsius difference. I would definitely attribute that to the glue. Another thing I can tell you from experience removing LMP from die is very easy. Just use care when removing bracket. I am one of the clumsiest people there could be and I have an inpecable PCB and no damage to die nor to pins. If you decide to sell glue it when you sell it.

Thanks for the info. My temps are pretty equal on all of the core now. What if you install a small bead of some type of adhesive on the outside edges of the IHS? Would that affect temps?

I don't get these results. I have a 3770k running at 4.7GHz now with a +.140 offset. My temps max out at 82C with Prime 95 and I'm on air cooling with a DH-14. You are using water cooling and are getting insane temps pre delidding. I'd say you got the shitty luck of the draw with the IHS being concave perhaps.

All CPU's are different. My previous 3570K needed 1.35v's to hit 4.3GHz. As they say the we play the Silicon Lottery.

Also the DH-14 and H100 as pretty much the same as far as cooling goes.

Not only did I gain 200 MHZ but I also gained lower temperatures all around. I also gained a closer temps on each core. My experience using FSX is smoother

If it is a very thin layer I do not see why not.

I definetely agree with you the IHS was pretty bad when I started to lapp. Do keep in mind that I only went up to 2500 grit. But I atributte the succesfull delidded to LMP mainly.

Ah that makes sense. This makes me wonder what kind of improvements I might see but I'm a bit chicken to take a razor blade to my cpu.

:confused: Why would you do that? A Cooler Master Hyper 212 Evo is only about $30.
If your case isn't quite that big, a Xigmatek Loki is ~$25.
Still too big? Try something like this $35 Cooler Master HSF.


You're talking about a 10-15% cost increase. If you could hit 4.4GHz with a stock cooler on a delidded 3570k, then that would be the ultimate budget choice, leaving no real need to spend any extra on cooling.

The lower temps you got, didn't that let you overclock more? Or was the chip sort of hitting a ceiling even though you had some leeway on the temps being rather low?

I would advise against a stock cooler. There are some 50 dollar coolers that work wonders. In fact if I had the space I would get rid of the H-100. Delidding is gonna cost at least 22 dollars if you put LMP including a descent Thermal grease plus 10 bucks in sand paper for lapping if your IHS is not flat which most likely is the case. Do not overclok with the stock it will overheat your Chip

Correct My chip's ceiling is 4949 with lower mid 80 to low 80 s on full loadss @ 1.552 volts if I try 5.0 i saw it trying to grab 1.65 to 1.7 that is nitrogen territtory. My chip is just stubborn

What are you volts @ 4.7? I can't see it in the picture. Are you keeping it @ 4.7 now 24/7

EDIT: Wait - I think it says 1.230 ??

yes but do remember I am running offset voltage so the actual voltage is 1.312 which it would indicate that it could hit 5.0 but like I said it gets crazy after 4.949 as far as 24/7 I run it stock

Are you getting any WHEA errors in Event Viewer?
Of course remember I am using Prime 95 but nothing major. I personally do not guide myself through Whea for stability because I could run FSX ultra settings leave the plane flying all night long come back in the morning land it. close the program look at my event log viewer and find no errors. So that is what matters I have never BSOD on this system except when I overcloked my Ram or I tried 5.0 GHZ other wise solid I fly FSX almost daily this is at 4.8 GHZ. I hope this helps
