3770k IHS Removals - CPU temp dropped from 79C to 71C

[G.Foyle]

Am I right under the assumption that the removal of the IHS and retention bracket only works with waterblocks and not air cooler as they would bend the socket pins due to their weight ?

No, it works fine with air coolers, too. Socket has plastic ridges between pins that the CPU substrate rests on and pins only exert their own pressure against lands. It's the same with IHS, only without IHS you have to distribute the pressure evenly across the whole substrate. If you only pushed against the die, the substrate might bend and not make contact with all pins, or even the die might crack.

PcCI2iminal, did you re attach the IHS with glue or something or is it just loose and held together by the cpu socket clips on the mb?

nothing
just held together with the retention bracket

[Eldonko]

Cool thanks. You realize a lot of people are going to kill their CPUs trying this now right? lol

The Heratkiller has no stop screws, so it was no problem for me to mount Waterblock without IHS. Only had to remove the retention bracket.

just send the bill to Intel Corp!!
j/k

KKKKK

i think CPU370 has no stop screws also,i will check it and i will run my naked 3770k on water,i believe its possible to prime it at 5GHz or more

here is what i got on water with same but unmoded 3770K

I want to know how a vapor chamber performs when attached directly to the ivy bridge die. I'm guessing with the right noisy fan it performs just like any water cooling. come on come on!!!

I did it with Prolimatech Super Mega, using two flat aluminium spacers between mounting hardware and cooler base to compensate for the thickness of missing IHS. I piled several layers of tape on both sides of the die and measured the thickness with digital calipers to make sure my tape spacers are the same height as the die.

you sir are a gentleman and a scholar. can we get all the ivy bridge stripping stories and pictures in one place somehow? to document this great change of scenery.

who will be first to sell ivy bridge shims?

I got a drop of almost 15 degrees on my 3570K since I changed the original TIM with MX-3. Unfortunately overclocking does not change and under Prime95 x64 AVX - In-place large FFTs, it is unstable at the same frequency of 4700MHz of any voltage.

After

But now you can put some more vcore on it. Maybe it helps to clock 100 Mhz higher.

[Endgame]

Anyone think indigo Xtreme would work under the IHS? My concern would be repeated reflow given the temps, but on the plus side it would attach the IHS back to the core a little more solidly than paste alone. Also, any thoughts on lapping the underside of the ihs, or is it already flat?

[st0ned]

You would need an special edition of IX since I don't see any of the actual types of IX reflowing on the core surface.

Naked core on water


unmodded 3770K at same clock and voltage range ,just for comparo


naked core with AS5,temps dropped 10c !!


5GHz!!!!

great pic. thank you for sharing.

[Kallenator]

Wow! Brave, reminds me of the Socket-A days, bring on the safety shims for me nerves

I suppose the block's retention screws pushes the CPU hard enough down to not need the LGA metal lever fastener?

Is anyone taking the time to lap their IHS as well?

Hi All,

I have been playing with Direct Die cooling myself and came across a few issues, I am using an EK Supreme HF to water cool the chip, however with the IHS removed and the Stock retention bracket in place the block doesn't make contact with the top of the die. I have also tried removing the retention bracket and tried to get the CPU block to make contact with the socket, however this has resulted in no post with CPU LED illuminated each time. I have when using this method tried to pack the block so that it applies more preassure to the chip but due to the block only making contact with the Die I don't think the load was even enough across the whole chip so didn't want to push it any further.

I have some small pieces of copper to hand and was going to cut these so that they pack the Die up so it is level with the Retention bracket and then mount the block on top of that. I will get some pics later if I can to show what I mean if my description isn't clear. Unless you guys have any other thoughts on what I can do to resolve this.

don't waste your time. switching from one precisely crafted piece of copper to a random hack piece of copper is not going to prove fruitful. it doesnt matter if it is a little thinner

[Astennu]

I also removed the IHS. I gained 12c when using 2x MX4 vs 1x AS5. Room temperatures where both the same 24c and i was running 4500 MHz 1.25v

[Darknight]

I decided to void the warranty
removed the IHS





applied only Gelid GC Extreme ride and soon after ran Linx and dropped 8 º C warmer in the core.
now is wait a few days and try another thermal paste.

Now anyone who has already taken the IHS and applied MX4 what differences?

Did you removed IHS, replaced TIM and reused the IHS? or you left die "naked" with direct contact with HSF?
12'C is a lot, is Intel using the crappiest TIM they found?

Guess I will have to do the same as soon as both 3770K's arrive, will do some before/after tests.
Too bad the only HSFs I have to test are the stock Intel and a Corsair A70 I have lying around ... when I see the results I will have to decide if A70 is enough :P

[Conquistador SW]

12'C is a lot, is Intel using the crappiest TIM they found?

I think so, I got 15C lower by replacing it with C Liquid Pro and MX4 and I just placed the IHS back, so maybe I could gain more by removing the IHS altogether. It looks like the TIM that I used to find on 5 year old motherboards.... very dry and a thick layer.

I have the original HF supreme and am direct die cooling it without any issues.. removed the retention bracket and just placed the block evenly down and booted it up. cpu was taped down in place with some electrical tape. nothing special
