[Reborn] OC3D Delidded Ivy Bridge Club

@grassman - thanks for that, I hadn't realised anyone had released a product specifically for this yet.

I admit, I'm half expecting future CPU's to forego the IHS entirely. After all, many GPU's are doing this now. My reference 680's have no IHS, so nVidia obviously consider it a good idea. Even some of the previous gen 580's did not have an IHS. This has got to help cooling as it's one less thing for the heat to traverse. Certainly in the case of my 680's they run very cool, despite being at a much higher vCore than my hotter 570's - obviously that's on air, my 680's are on water now just like my 570's were.

I guess though a CPU without the IHS - when a heatsink MUST be added, unlike a GPU which is pre-assembled - runs the risk of damage during assembly by the novice system builder. That's be one good reason not to do it, though for the enthusiast market...well, we shall see.

I didn't know anyone had brough out a 'direct to die' kit.

If you google direct to die lots of people have done it.

To DIY it the motherboard locking cage needs removing and then washers need to be added to space the water block up higher. There are a few guides online.

For me though going direct to die would cause me to have minor heart failure every time I removed the block. One scratch on that die and it's all over.
Getting the correct mounting pressure is a bit of guess work.

The temp jump from non delid to delid is pretty huge (20-30C depending on cooling) the jump from delid to direct to die is much smaller and for me it's not worth the added risk and messing about.
I would do it if I had a spare one and a test bench but not for 24/7.

But saying that, now EK have that block out....... Got to be honest it's got me itching. Bad EK! Why do you do this to me?

It's fun* project, and the results can be pretty impressive. However, for me at least, I do agree with you & would be wanting to go direct to die. Hence me mentioning it really.

Heh yeah, I've actually got my old AMD 2400+ next to me now as well as an old Pentium dual core laptop chip - both have exposed dies. From what I can see, the die material is pretty robust so, assuming IB's are the same, I'd not be overly concerned about damaging them.

This does show how poor IB's TIM is though. I mean, I see temps similar (slightly lower for the most part) to you Genesius, yet I am running a Sandy Bridge 2500k @ 4.8 with 1.440 vCore showing under heavy IBT / OCCT testing - it's not the best chip to be fair. I thought my temps were a bit high too & hope to update my CPU block & lap the CPU at some point. My cooling is pretty epic though, slightly weak CPU block aside.

@FTLN

I'd assume not (to be safe) as it says it's designed for EK's own Supremacy CPU Block.

I disagree. I've had a 25C drop in temp. Now in my opinion, 25C is worth it. Would it be worth going direct to die for 5C more? To me no. I can get my chip to 5.2 and have now managed to get 5Ghz stable and stay under 90C. So the extra risk in going direct to die for the extra gain over just delidding isn't worth it. Your chip would have to be really really terrible to NEED to go direct to die.

SCOOB - yeah sandy bridge is much cooler. The die in the sandy bridge is soldered to the IHS so the heat transfer is much much better. The bigger die transfers the heat to the IHS better because of the bigger surface area.
Don't know much about sandy bridge.

It's all about the height of the block and the pressure needed on the die. You can DIY this and for any other block that's not an EK Supremacy, your going to have to. EK have obviously worked out the optimum height and pressure for direct to die with their block. If you use this kit with another block it will still need adjusting, so you'd be better off doing it the way loads of people have been before this kit came along.

It involves a vernier to measure the precise height of your chip including the IHS, then the height of the IHS is taken off to find the correct mounting height then some washers and shims to get the right height for your block.

That's the way I feel too. I've had a 20C drop and I'm now getting 4.8 with max temps under 70C. I'm now voltage limited not heat limited so I think it's more hassle and risk than it is worth for a 24/7 setup. For experimentation and benching then sure.
 
You've got to agree that a 20c+ drop is HUGE and can only aid overclocking due to the reduced temps & resistance. If I had a 3570k rather than a 2500k right now I'd likely be seriously considering doing this...having put aside the money for a new CPU if it all goes horribly wrong lol.

+1 I'm now voltage limited rather than heat limited too.
 
Re-done all my loop, and reseated the CPU block, and IHS, all with NT-H1 - cba with the Coollab stuff yet.

For 4.5ghz (1.205v), folding CPU and GPU gives CPU temps of around 55-60, with GPU close behind.

Idles at around 30,

Prime95 has it at around 57-63ish.

May try to push the clocks more at some point, but I'm pretty happy with performance and temps anyway, so might as well just leave it.

Your should go for 4.7 / 4.8 you got a nice chip there....
