its not a quicky job. You need to sink the razer blade about a 1mm and your safe, id not go farther imo. It took a hammer for me, tapping with a small wrench would not budge it. Hammer ftw. youll know when you are right, youll just know. DONT FORCE IT, come back and try again if your frustrated, better than wreaking the chip as Cakewalk mention in the first post. TAKE YOUR TIME.

Now that ive done mine kind of wish id left it, i didnt have a heat issue before, just like doing stuff like this. It did not decrease it enough to warrent the mod...

THere is a place for this mod and the saying goes "if it aint broke-dont fix it". Its a fantastic mod but really a last resort type thing. If your temps are good, you dont need to do this.

Cakewalk, not to take from this thread, its fantastic i agree but it seems some are treading in dangers waters trying this mod. Some warning is due here, more so now with all the attention it is reciving.

Good job just the same

Great stuff here man.

What you think the success rate of doing one of these by yourself, from the results this looks good enough to attempt.

Well I got the IHS off, I think I ruined my chip tho (see pictures)

310764_10150358744103016_535793015_8426909_1649173088_n.jpg

the corner and the edge of the chip have copper showing through.

and

too much twisting force, heard a crackle, and the silicone is bent down now, touching the pcb.

i think what my issue was, was i was trying to use x-acto knives. they're really thick. so i was trying to cut away the silicone to get the knife in there.

i ended up breaking open a razor and that razor slid right in between the 2 units (altho still cutting the glue was turning into a challenge) so as a last resort I went to CVS and got double edged razors. which are as thin and flimsy as the one out of the broken gillette - but theres more to grab so i could "cut" easier.

I'm this far, might as well complete the job and see if it boots.

Thread Starter 
You tried to take off the IHS by pulling up on the edge? You basically have to seat a razorblade flat, like on the side where the PCI slot connector is and just tap with an end of the screw driver or as cravin said hammer ftw...

The slicing is just basically getting just enough for the razor not to move when your tapping it....

Keyan, that sucks, I can see a little bit of copper on mine but thats from scraping off the black adhesive from the IHS... it works just fine. I dunno man, give it a try. Like everyone says, its a super risky mod, probably 10/10 on the risk scale. Maybe try to place the IHS back on and try to boot it up...to check... I'm not 100% but I think the silicon is just there to protect the insides...so if you scrape it off to the copper your still ok...but not sure...only 1 way to find out. Twisting? huh? I never twisted anything...you tap the razor in like 1mm like cravin said, then bend up the razor to break the seal...

Cravin,
Did you sand down the IHS alot? If you have heat issues its because after u cracked the IHS from the chip it won't seat as close...because the glue is in the way...so you need to either try to scrape off that glue and/or sand down the IHS.... Just replacing the TIM will most likely get you worse temps.

Jonny,
50/50 man. You tap the razor in too far and your SOL...I had no idea what I was doing the first time but I got mine off with no problem.... I easily dropped my temps a good 10-14C with this mod...so its upto you... I tinker with stuff like its my job...so I still woulda done it knowing the risks... so fair warned... Like Keyan...you could ruin the chip possibly....

this mod is very tempting, i see my temps reaching 81c when playing games on the stock cooling, i may have to try this since i dont like those temps.
post #48 of 257
Well, it is ALIVE. running it right now.

gonna make some runs with it. it seems to be idling about the same 28c-30c.

I was also unaware of the new OCCT. So I just got that this morning and I'm running that same test, error check off. For some weird reason Nvidia forces Vsync on when I try to run the test full screen, so I have to run it windowed...weird...
Well scratch that. For some reason OCCT isn't generating me graphs...well it is, but only at certain times....guess they've got some bugs to fix on the new OCCT...


Thanks guys! I'll start that table of users that've done this mod and their result.


Znarf, You did this on both your 560ti's in SLI config? What was your before/after temp?

Ah, figured it out...
Here's my chart from my test. I'm upto 1.075V now @ 970MHz core, maybe try for 1GHz?
6318943633_472c704383_b.jpg

nope, only did the mod on my first card (top card) i've decided to do it when i got back my card from RMA its just ASUS slap a new TIM on it and really disappoints me because the temps were really high (as my previous post) got to 95C under 5 minutes of playing MW2 and minimum of around 40C to 42C just right after i power my pc, the second card is stable with negligeble chages. on the MSI AB graph you can see the temperature difference on my 1st and 2nd card which around 5D on idle but during load its about 13 to 15D? mybe I needed a bit more of lapping on my first card? problem haven't got time to do it for the moment. anyway thanks for this awesome guide biggrin.gif oh BTW i'm on 960Mhz @ 1.035v during the test. The new version of OCCT is not so friendly.
