CPU Delid

[Light-Yagami]

Hi guys,

 

Just wanted to know if any you knows specific delid tools and liquid metal paste from experience and what works best

Another important question, how much temp decrease can I expect from a 6700K? I plan to OC it to 4.8 ghz, but I don't like it runing above 75 on liquid cooling.

 

Your answers are always appriciated!

This is the paste used on the video:

Use the tool that they have linked in the description, if you want to do that...  But, the 6700K has fairly good thermal paste, so I wouldn't recommend it.

That's exactly what I want to know. How much difference. I know 7700k has shit paste and delid is a necessity, but if I'm only gonna get 3C improvement, then there's no way I'm doing it.

Depending on the Thermal Paste, you can get 3-5C improvement. Not worth it IMO

it's not the paste, it's the distance between the die and the IHS.

I've seen sites claiming a 20-25c improvement under heavy overclocks.

With an AIO, delidding will not result in 20C lower temps...

It's not about the thermal paste. It's about the glue itself. Dow Corning 5688 has been used on every Intel CPU since 2008, so Skylake's paste is no different than Haswell or anything else.

Again, it has the exact same paste as Skylake. It's not the paste, but the glue that holds the IHS to the substrate. The reason Kaby runs hotter, is because people are pushing higher clock speeds and voltages. As for the answer to your question, it depends on several other factors. I shaved about 23C off of my 6700k after delidding and using CLU. 

 

As for which paste is the best, Coollaboratory Liquid Pro is considered the best, but only by about 1-2C compared to Coollaboratory Liquid Ultra, and is much harder to spread. CLU is the easiest to work with, and is also cheaper. Delid the CPU, completely remove the glue using a credit card or a flat wooden edge (paint stick or something similar) and slightly mar the underside of the IHS. Expose a little of the copper so that the CLU can easily bond to it (gallium doesn't bond to nickel all that well). Cut the bristles of the supplied brushes exactly in half, and dip the tip of the brush into the CLU syringe. The amount that ends up on the tip should be plenty enough to paint the entire die. Spread a very thin, even layer on the CPU die, and repeat the process for the underside of the IHS (dipping again, and drawing a slightly larger, thin square). If you find that you didn't have enough,feel free to dip once more, but no more than that.

 

It's up to you whether or not you want to re-glue the IHS using Loctite or a similar adhesive, but I personally do not re-glue mine. CLU needs to be reapplied every 1-2 years to maintain the best thermals. As for best paste to use in between the IHS and your heatsink, just use your preferred silicone based paste. CLU on top of the IHS only shaves another 1-2C, and is an expensive waste to use as a paste. I know people these days prefer Kryonaut or Gelid Extreme (gelid being my preferred choice as well, due to cost). If you want to see my results, feel free to visit this thread:

Simply not true. @Lays has a custom loop that will destroy any AIO you throw at it, and he has seen 20C differences after delidding. Where in the world are you getting your false information from?

if you only get 3C differance you did something way wrong... 

 

use thermal grizzly cryonaught for the paste, its the best stuff around AFAIK, delid should give you ~10-25C improvement

I KNEW IT! I knew you would link that flawed methodology video. Every single enthusiast in this forum debunked that video in that video's official thread. I highly recommend giving it a read. 

TL:DR? Linus had no idea what he was doing, and was completely wrong. His testing methodology was flawed, and was nowhere near accurate.

Thank you. This is a pretty elaborate guide, I hope I can do it properly. It will cost me a whole lot for the tools, but if I can get 15C lower temps, then it's totaly worth it.

Again, it mostly depends on how bad the glue is. However, I have never seen a person that delidded, fail to get 15C when switching to a metal paste. The metal pastes are about 5-10C better than the silicone pastes, but require extra care when applying. I recommend using painters tape or a thin layer of clear-coat nail polish on the gold contacts (gallium bonds to gold, and will short your CPU out) near the die (should be 4 small contacts on the 6700k) and you are pretty much good to go as far as being risk-free goes. If you are going to re-glue it, I highly recommend loctite as it's organic and be dissolved with acetone without causing any damage to the CPU (I bathed my CPU in acetone to make the original glue easier to remove).

 

Now, if you do cover the gold contacts, you can afford to get away with more CLU, as more CLU won't hurt your temperatures, it's just the risk of it spilling over that we try to avoid by using a thin layer. @Lays just recently caked his CLU on, and saw a great temperature decrease, but he's crazy anyways.

Man, to be able to run at 4.5ghz with like 55C, that'd be awesome. I'll do it, there's no doubt about it. I don't plan to re-glue it back, I will do exactly as you told me. Thank you for your advice!

You can get even worse temps after doing it.

Heck i got 10C down on a H80i with a 3570K back in the day! Big boy rad is obviously better but for a little 120mm it was pretty hardcore. 

 

It's a absolutely hilarious seeing the noobs link the LTT video.

one more question. What if I apply just a regular thermal paste? Same everything but no liquid metal? 

[Bakerking31]

I am going to do this next week on a 6600k currently at 4.5ghz but on air.  Mostly just doing it because I can, it will be interesting and I haven't done it before.  I am thermally regulated right now, but I don't want to go past 4.5ghz I just want cooler temps.  I will post my before and after results.

Will you use liquid metal or regular thermal paste?

a simple vice is more then enough to do it safe as long as you are not retarded.

CLU, I ordered it a few days ago.

 

Also going to use a razor blade, so no special tools.  Cant say I recommend it though as I have never done it before.

I have everything exept for liquid metal paste. I consider myself capable enough to delid a cpu without taking a shit while doing it. The only thing I want to know now is if regular thermal paste is also okay and how much decrease of preformance there is compared to liquid metal paste

It will still be a reduction of temps, just not as drastic as the liquid metal TIMs. I know people that use Kryonaut on their bare dies and still see a 10-15C drop (again, mostly because the glue itself is bad). Use whatever you feel comfortable using. I personally prefer CLU, because liquid metal is superior than silicone based pastes by the tune of about 5-10C depending on which pastes you use. Most DICE or LN2 enthusiasts don't use liquid metal TIMs because gallium is not rated for under 10C usage, and tends to ruin when going subzero. 

 

If you have the time and money, I recommend testing both (maybe start with silicone paste first, then try CLU) and see the differences for yourself. That's the easiest way to know which is better or "worth it" for you.
