De-lidded and lapped my Haswell 4670K

post #1 of 5
Thread Starter 
Hey guys I haven't posted for ages but had to share this with you!

I bought a 4670K the other week and got what seemed to be the worst sample. Needs 1.27V to be stable at 4.2GHz, but the worst part was that under IBT it was hitting 90'C+ so was no room for further OC'ing.

Anyway I've been looking around the net as you do and stumbled across removing the heat spreader, clean it up and apply some better TIM. So out of desperation I did. smile.gif

I was skeptical so im sorry i didnt take any before and after photos etc. but it has dropped my temps by nearly 20'C!!!! I have just ran IBT and the hottest core was 73'C so hopefully now can push the OC a bit further.

As for the process itself i used the "vice method" and it worked a treat. Looks like the issue for the high temps is the adhesive used, not allowing the heat spreader and chip to compress enough as there was a quite a thick layer of TIM in between.

Just needed to let everyone know because i really am shocked!

You think your chip is bad? I can't even get 4.2ghz at 1.3v, and I have a 4770k tongue.gif

Anyway, glad to hear that it went well! It seems the vise method really is the way to go. Do you know any other specific, documented cases of people delidding Haswell chips? I know it's being done, and that the whole process is very similar to Ivy Bridge, but it's surprisingly hard to find detailed accounts of Haswell delidding.

What did you do about the VRMs? Did you cover them with electrical tape/nail polish? Or did you use a non-conductive thermal paste on the die? As far as I know this is the only difference between Ivy/Haswell delidding.

I'm just trying to get as much info as possible before I try this myself.

I used Cool Lab ultra as you can spread it very thinly. As for to VRMs and did consider using Vasaline or even some electrical tape to insulate them but decided the gap was sufficient enough that it was not required. I did some trial runs to make sure that when compressed the TIM stays clear of the VRMs! As long as you dont stick too much on you should be fine

Think it would be better to just use MX-4 since it's nonconductive? Obviously temps would suffer a little bit, but the main point of delidding is getting rid of the black stuff...so I'd imagine a nonconductive TIM would be safer and only a little bit less effective.

Edit: also, lapping the IHS would probably make up for the few degrees lost by using a nonconductive paste.

Don't mind me, just thinking out loud.
