Hello overclockers,

I currently have a 4770k and a CoolerMaster seidon 240m w/ Arctic Silver 5 thermal compound. I am planning on delidding and lapping soon and sometime in the near future upgrading to a custom cooling loop with the EK Supremacy copper cpu block. I am planning on using the coollabratory liquid ultra under the IHS but do not know what to do between the IHS and the cpu block. I was thinking of using the AS5 for now until I get the custom loop but after that I don't know if i should use the liquid ultra or a non liquid metal. I am unsure of this because people say that the liquid ultra will "weld" your IHS to the cpu block. I am trying to do a very aggressive overclock, 5+ GHz and be able to pass Intel burn test without throttling.

So i have several questions:

1. Would it be worth the slightly better temperatures of Liquid Ultra over a high end paste since it welds to the cpu block?

2. EK has the "naked ivy" kit to forgo the use of the IHS at all with their Supremacy blocks does that work with Haswell? And if so would that be a good idea to get, should I use liquid ultra or a high end thermal paste?

3. Quick tangent question, should i put liquid ultra on my graphics cards? I have to ASUS DCUII OC 760s

4. If I do use a high end paste rather than liquid ultra, what should i use? I have done lots of research and people say that the Phobya He Grease is the best while others say that Innovation Diamond 24 is the best.

5. Is cpu lapping for the 4770k something that will help temperatures much? I will already be voiding warranty by delidding so that is not an issue. Pretty much any improvement in temperatures would be helpful.

6. Final question, what is the safest maximum voltage for the 4770k? Completely disregarding temperatures.

I would like to thank all of you in advanced for the help

There are some things that internet research just can't get you.

1. I wouldn't use Liquid Ultra between the IHS and block, the gain isn't worth the extreme PITA of removing it. Just use a regular paste, I use PK-3.

2. It provides slightly better temps, but I wouldn't risk it after hearing some of the stories I have. The problem with direct-die cooling on an LGA chip, is that once you remove the heat spreader and load plate, you no longer have even pressure, pressing the cpu down onto the pins inside the socket. Instead, you have the pressure from the cooler, all focused into the die. Over time, the cpu's pcb will warp from the pressure of the pins. On top of that, you have a pretty decent chance of cracking the die if you tighten the block unevenly. I would only use regular paste between a die and cooler, because of the die's fragility when you will inevitably have to remove the cooler, and the difficulty of removing liquid ultra after it has hardened.

3. I would just use regular paste.

4. HeGrease is great stuff, along with a dozen others. Check out this paste roundup.

5. Lapping will have a very small impact, unless your IHS is horrible uneven.

6. I am at 1.35 right now, but I personally don't really know the limit. Someone else will have to chime in on that one.

1. That's what i was thinking, thanks for the second opinion.

2. That is a good point, ill leave the ihs on it and just use the liquid ultra under it, plus itll weld it back on

3. Ok ill use whatever paste i end up buying

4. Ill look into HeGrease and Diamond 24

5. i took a straight edge to mine, it didn't seem uneven at all in fact

6. Ok maybe ill start a separate thread for that, because as I said i am going to try to overclock it as much as i can and if my temps stay fine while the voltage gets dangerous i would not want to ruin my chip

Thanks for the help +1

Check out the Intel CPU forums here on OCN, there's almost certainly a 4770K owner's club thread, and likely many others with OC tips.
