How safe is to do delid? and does deliding help to Overclock faster?
post #192 of 218
I used the hammer/vice method, see attached:
http://www.overclock.net/t/1376206/how-to-delid-your-ivy-bridge-cpu-with-out-a-razor-blade
There are other methods, one using a razor blade.

Is it safe - hmmmm - If you do your homework and are patient/careful then you will minimize your risk of failure.

Also, what chip are you thinking of delidding, Ivy/Haswell?

From what i have read here, delidding will reduce your temps which may allow you to increase your overclock.

if your limited by heat due to bad connection with the ihs and chip yes a delidd can do 20c in good cases and increase a better OC or temps.-

Yes I saw a tiny gleam of copper. I covered it up with my wife's nail polish. Haven't had any problems. Overclocked now to 4.2 Ghz on air with Noctua DH-14 CPU cooler. Idles in the 30's stress test puts it in the high 60's to low 70's. (degrees Centigrade)

The problem I had with nail-polish is that after it went through a few heat cycles, it simply let go of the PCB and attached to the IHS. It essentially became very brittle, plastic like and no longer covered the nicked part. This discovery made me draw a few conclusions.
1. In my case, covering the nicked part didn't matter, no evidence for arcing or something similar. Be warned it might not be the case with your CPU.
2. If I had to do it again I'd just use a tiny drop of non-conductive thermal paste, since it won't let go of the PCB so easily. That said, for now I'm just running my chip without anything to cover it up.

Probably right as to nail polish letting go of the PCB, but I'm not going to find out soon if ever in my case, because I won't remove the IHS to find out. Thanks for the good tip though to use thermal paste on a nicked die. thumb.gif Used Noctua NT-H1 on CPU under IHS, and IC Diamond Carat 7 from IHS to Noctua DH-14 cooler. No problems encountered so far after weeks of trouble free use.

Necro? Necro (probably).

Just another random delid success story here. Decided on a whim to finally get around to delidding my 3570k. Kinda disappointed with my temps and AS5 atm, so I might remount later, but as far as the delidding process itself, it went super well. The chip was a little loose on the vice for the first handful of whacks but on the 3/4 try I managed to get it. Unfortunately, I've got marks on the side of my IHS but I don't really care about that. I'm more interested in the temp drop. Anyways, thanks a lot to everyone at OCN for keeping this kind of stuff awesome! Good luck guys.

Not sure how to vote. Not what I would call a 100% success, but the CPU seems to work.

My story.
Ivybridge 3570K has been installed for a while under a closed loop watercooler. (H80 I think. Can't remember) was always planning to delid, properly watercool and properly OC. (was not happy enough with OC temps under the H80 to really push it with that cooler.)

Anyway, the custom cooling stuff finally arrived and delid day came.

Tried the hammer and vice method, but no joy, the IHS just simply refused to move, care, patience and precision would not make it move, care, patience, precision and force also failed. Once the pcb started showing signs of separation and the IHS itself was starting to look like it had impact damage I decided to sleep on it and go fetch some razors the next day.

Convinced the chip was almost certainly dead and resigned to buying a new CPU I tried a scalpel from an art store, this appears to have nicked the pcb, tiny glitter of something shiny in at least one place, maybe 3.

Old fashioned razor blades can NOT be found in bricks and mortar stores here in Sweden, but I actually found some kind of scraper blade that is not much thicker than a razor and thinner than a Stanley knife blade and also came with a handle. (they are double sided exactly like razors, but not as thin and or flexible.)

With a rocking motion, and avoiding the lifted edges of the pcb (from the failed hammering) I got the IHS off pretty quick and very safely.

On closer examination, once cleaned up it looks to me like the silicon glue had sucked down real tight and was never going to shear with the hammer. Also, once I had cleaned it up with some isopropyl alchohol I could see one nick through to copper and maybe another two visible only with magnifying glass when wet with cleaner.

My longer term plan is to go direct die, but for now I had to do a rough lapping of the IHS just to fix the damage the vice had done.
(I only had access to 1200 grain paper, so its not the best lapping job ever.)

Its back in the rig under the H80 for a quick test and apparently working!
Will pull the IHS out again for proper lapping and see what the temps look like with a proper water cooling solution.

If I do this again. (and I probably will) I will go direct to blade. The hammer is just not working for me.

Oddly, when I powered the pc up the first time it went straight to BIOS with the message "new cpu installed" so there may be some damage.
Although both memory channels appear to work, it identifies as the correct cpu type (3570k) and the memory cache counts all see ok.

Once I have lapped the IHS and covered the nicks up with silicon glue I'll push it as far as possible with OC and stress test to see if its ok.....

No worries. I had that happen to me before with the same cpu. Happens sometimes, sometimes not.
